Working with PNT

7 questions
How do we get started with PNT?

Start with a conversation. Contact us with the transactions you move, the trading partners involved and the systems you run, and a Post-n-Track specialist will walk through how the service fits. Providers who are ready to submit claims and related transactions can enroll directly; participation eligibility and pricing are determined from the enrollment selections, and the implementation team follows up.

Does PNT require a long-term agreement or exclusivity?

No. Post-n-Track is offered with no long-term agreement and no exclusivity. Organizations keep their existing connections and add or move transactions on their own schedule. Read more on the How It Works page.

How long does it take to switch to Post-n-Track?

It depends mostly on payer enrollment. Every payer relationship has its own enrollment posture: some accept a new submitter immediately, some require a signed EDI trading partner agreement, and some require a 30- to 90-day enrollment window per transaction type. EFT/ERA enrollment is governed separately under the CAQH CORE EFT & ERA Enrollment Data Rule. Payer-by-payer enrollment status is the single largest factor in a switch timeline, and the implementation team works it payer by payer. Read more on the Clearinghouse Alternative page.

Where is our data hosted, and does PNT keep a copy?

Post-n-Track runs on resilient AWS multi-zone infrastructure with intelligent routing and failover, and it keeps no copy of your transactions. The service authenticates, validates, translates and routes data in transit and retains no PHI at rest, so there is no central repository of your data at PNT to breach or to recover. Read more on the Security & Compliance page.

Which organizations does PNT work with?

Health plans, providers, revenue cycle companies, third-party administrators, government programs, and healthcare IT and AI vendors: more than 2,000 healthcare organizations over twenty years of operation. Each has its own page under Industries, with the transactions and workflows that matter most to it.

What certifications and audits does PNT hold?

Post-n-Track's controls are verified by independent third-party audits on a recurring cycle. The certifications and accreditations, and what each one covers, are listed on the Security & Compliance page.

I'm an existing customer. Where do I sign in?

Customer Sign In is in the bar at the top of every page and opens the PNT customer portal. For help with enrollment, onboarding or connectivity, contact our Implementation team at sales@pntdata.com or (860) 257-2030.

Platform

15 questions
What is Post-n-Track Gen 3?

Gen 3 is PNT Data Corp.'s current healthcare data platform. It authenticates, validates, translates and routes X12 EDI, HL7 and FHIR transactions in transit and retains no PHI at rest, eliminating the central repository that makes traditional intermediaries high-value breach targets.

Read more on the How It Works page.

How is Gen 3 different from Gen 1 and Gen 2 systems?

Gen 1 was batch store-and-forward, where retention was a byproduct of the transport model. Gen 2 added real-time paths but kept the central store. Gen 3 removes the store: the same accept, translate, validate and route functions, without retaining the transaction afterward.

Read more on the How It Works page.

Is zero-residency the same as encryption at rest?

No. Encryption at rest protects data that still exists and is still reachable by anyone with valid credentials. Zero-residency means the data at rest does not exist. The distinction matters most in exactly the scenario encryption does not cover: a compromise using legitimate credentials.

Read more on the How It Works page.

What is the difference between X12 EDI and FHIR?

X12 is the batch-oriented standard for administrative healthcare transactions (claims, remittances, eligibility) using hierarchical envelopes and positional segments. FHIR is HL7's REST- and JSON-based standard for real-time exchange, modeling data as linked resources. They are different models of the same domain rather than different encodings of one model, which is why mapping between them requires decisions rather than mechanical conversion.

Read more on the Data Engineering page.

Why is healthcare data integration so difficult if standards exist?

Because the standards model the same facts differently and permit local variation. HL7 v2's Z-segments are non-standard by design; X12 implementation guides allow payer-specific conventions; FHIR profiles vary by implementer. The obstacle is variance within standards rather than the absence of them.

Read more on the Data Engineering page.

Do you need a data warehouse to translate between EDI and FHIR?

No. Translation is a stateless transformation on the transaction in flight. Staging repositories are an implementation choice rather than a requirement, and they reintroduce the retained-PHI exposure the transformation itself does not need.

Read more on the Data Engineering page.

What is shift-left validation in healthcare EDI?

Shift-left validation means enforcing implementation guide conformance and known payer edits at the point of ingestion, before a transaction is transmitted, rather than discovering the failure through a rejection or denial. The transaction that never had to be sent is the cheapest one.

Read more on the Data Quality & Validation page.

What is the difference between guide conformance and payer edits?

Guide conformance is deterministic: does the transaction obey the mandated implementation guide (segment presence, loop placement, identifier format, date validity). Payer edits are local requirements layered on top, which vary by payer and change without notice. The first is a build; the second is ongoing operational work.

Read more on the Data Quality & Validation page.

How much do validation errors cost?

The cost scales with how late they are caught: a correction at submission, a resubmission cycle at 999, a resubmission plus aged AR at 277CA, and a full rework cycle plus timely-filing risk at adjudication. Specific figures vary by organization and should be measured rather than assumed.

Read more on the Data Quality & Validation page.

What is healthcare data lineage?

Data lineage is the ability to trace a transaction's origin, movement, transformation, and destination across its lifecycle: when a claim was received, validated, routed, acknowledged, accepted, and adjudicated. Lineage is metadata about the transaction rather than the transaction content.

Read more on the Tracking & Governance page.

Can you have full transaction visibility without storing PHI?

Yes. Visibility questions are answered by state and metadata: identifiers, timestamps, state transitions, validation results, and outcomes. None require the payload. Intermediaries that argue retention is necessary for visibility are conflating provenance with payload.

Read more on the Tracking & Governance page.

How does transaction tracking support compliance?

An append-only record of what moved where and when is the evidence an auditor requests, the basis of a trading-partner attestation, and how a dispute is resolved. It is produced automatically by normal operation, and it cannot be reconstructed later if it wasn't captured at the time.

Read more on the Tracking & Governance page.

What makes healthcare data AI-ready?

Structure, normalization, and consistency, so a model can consume it without preprocessing. The harder question is where that happens. Most approaches assemble a centralized repository first, which recreates the PHI concentration risk. An alternative is to keep deterministic processing at the edge and give models only de-identified structured results.

Read more on the AI-Ready Data page.

Can you use LLMs on healthcare data without exposing PHI?

Yes, if you separate the jobs. Deterministic engines handle the work that touches protected data (validation, matching, code lookups) inside the boundary. The model receives only the de-identified structured output and does the interpretive work: explanation, summarization, triage. The model never sees the protected data.

Read more on the AI-Ready Data page.

Why not just build a healthcare data lake for AI?

You can, and many do. The cost that usually goes unpriced is that the lake is a new concentrated PHI repository with a newer, less mature access model on top of it: the same structure behind the sector's largest breaches, built deliberately and recently.

Read more on the AI-Ready Data page.

Security

4 questions
How does zero-residency architecture prevent healthcare data breaches?

It removes the target. Traditional intermediaries accumulate the transaction history of thousands of organizations into one repository, which becomes the highest-value target in the sector. Zero-residency routes and validates in transit without retaining the transaction, so there is no accumulated repository to compromise. Only transactions in flight are exposed at any moment.

Read more on the Security & Compliance page.

Isn't encryption at rest enough?

Encryption at rest protects data that still exists. It is transparent to an attacker holding valid credentials, and credential compromise is the dominant pattern in large healthcare breaches. Encryption is necessary; it does not address concentration.

Read more on the Security & Compliance page.

What happens to my operations if my clearinghouse is breached?

Typically they stop. The system that held the data is the system that moved it, so a compromise is simultaneously a privacy event and an outage: claims, remittances, and eligibility halt across every connected organization at once. This is why intermediary concentration is a continuity question as well as a security one.

Read more on the Security & Compliance page.

What does 'Data Guardians, not Data Owners' mean?

It means PNT does not retain, use, or sell customer data, enforced by architecture rather than policy. A policy lasts as long as the current owner and business model. An architecture that never stores the data does not depend on anyone's continued intentions.

What is the difference between an 837P and an 837I?

The 837P (005010X222A1) is the professional claim, replacing the CMS-1500, used by physicians and other non-institutional providers, coded with CPT/HCPCS at the service line. The 837I (005010X223A2) is the institutional claim, replacing the UB-04, used by hospitals and facilities, and built around type-of-bill, revenue codes, and occurrence, value, and condition codes with a statement-covers period. They share a base standard but fail for different reasons: an 837I can be rejected for a type-of-bill or revenue/HCPCS pairing problem that has no professional equivalent.

Read more on the 837 Claims page.

What is a 277CA and why does it matter?

The 277CA is the Claim Acknowledgment, the payer's report of its front-end business edits, telling you whether a claim was accepted for adjudication. It is distinct from the 999, which only reports X12 syntax conformance. A claim can pass the 999 and be rejected at 277CA, meaning it is not in the payer's adjudication queue at all. If your workflow does not consume 277CA, those claims age silently while your system shows them as submitted.

Read more on the 837 Claims page.

What is the difference between a 999 and a 277CA?

The 999 reports syntax: did the transaction conform to the X12 implementation guide. The 277CA reports business acceptance: did the payer's front-end edits accept the claim for adjudication. Passing the 999 means it parsed. Only 277CA acceptance means it is being worked.

Read more on the 837 Claims page.

Why do claims get rejected for subscriber and patient loop errors?

Because the 837 hierarchy requires that when the patient is the subscriber, patient information appears in loop 2000B and loop 2000C is absent; when the patient is a dependent, 2000C is required. Systems that populate 2000C unconditionally generate rejections that read like data errors but are structural. The payer's rejection message rarely identifies the hierarchy as the cause.

Read more on the 837 Claims page.

When does an 837 result in an 835?

Only after the claim clears the acknowledgment chain (TA1 at the interchange level, 999 for syntax, 277CA for front-end business edits) and is adjudicated. Submission, parsing, acceptance, and adjudication are four different states, and treating them as one is a common source of aged accounts receivable.

Read more on the 837 Claims page.

What is EFT/ERA reassociation?

Reassociation is matching an ACH healthcare payment (EFT) to its corresponding Electronic Remittance Advice (X12 835). The match is made by comparing the reassociation trace number in the ACH CCD+ addenda record to the TRN02 element of the 835. Successful reassociation allows automated payment posting; failure sends the payment to manual reconciliation.

Read more on the 835 ERA Processing page.

What is TRN02 in an 835?

TRN02 is the reassociation trace number data element in the X12 835. Under CAQH CORE operating rules, its value must match the trace number carried in the CCD+ addenda record of the corresponding EFT, which is what makes automated payment-to-remittance matching possible.

Read more on the 835 ERA Processing page.

Why does EFT/ERA reassociation fail?

The most common causes are: the bank does not deliver the CCD+ addenda record to the depositor; one EFT covers multiple 835s or vice versa, breaking one-to-one matching; trace number formatting drifts between the banking and EDI paths (leading zeros, prefixes, truncation); the payment and remittance arrive days apart; or payer-specific TRN02 practice varies from the operating rule.

Read more on the 835 ERA Processing page.

What is a CCD+ addenda record?

CCD+ is the ACH format used for healthcare payments. Its addenda record carries the reassociation trace number that links the payment to its 835. If a bank does not pass the addenda through to the depositor, the trace number never reaches the organization that needs it, and reassociation cannot be automated regardless of what the payer did correctly.

Read more on the 835 ERA Processing page.

How do CARC and RARC codes relate to denials?

CARC codes state why a payment differs from the billed amount; RARC codes add supplemental explanation. Both are carried in the 835. They are the structured record of the payer's reasoning and the basis for any appeal, which is why treating the 835 as a payment amount rather than an explanation discards the most useful denial-management data available.

Read more on the 835 ERA Processing page.

Why do secondary claims get denied after a primary pays?

Frequently because the primary's payment and adjustment data from the 835 was not carried forward accurately into the secondary 837. The denial presents as a coding problem but originates as a data carry-forward problem between the remittance and the secondary claim.

Read more on the 835 ERA Processing page.

What does AAA error code 72 mean on a 271?

AAA 72 means the subscriber identifier submitted on the 270 was invalid or missing: the payer could not resolve the member. It does not mean the patient has no coverage. Common causes are a transcribed member ID, a name or date-of-birth mismatch against the payer's file, a dependent submitted in the subscriber loop, or an identifier that changed at plan year rollover. The correction path is to re-inquire with corrected demographics or to run coverage discovery, rather than treating the patient as self-pay.

Read more on the 270/271 Eligibility & Benefits Verification page.

What does AAA error code 41 mean?

AAA 41 indicates authorization or access restrictions: the inquiry was structurally valid but the submitter is not permitted to ask it of that payer. This is almost always a trading-partner enrollment issue rather than anything to do with the patient, and it is resolved with the payer, not by re-inquiring.

Read more on the 270/271 Eligibility & Benefits Verification page.

What is the difference between eligibility verification and coverage discovery?

Eligibility verification confirms whether coverage already on file is active and what it covers, using a 270 inquiry directed at a known payer. Coverage discovery identifies coverage the provider does not know about, which matters after self-pay registration, incomplete demographics, or an unresolvable AAA 72. Verification requires knowing which payer to ask; discovery does not.

Read more on the 270/271 Eligibility & Benefits Verification page.

What version of the 270/271 is required?

005010X279A1 is the mandated implementation guide version for the eligibility inquiry and response pair. Conformance includes correct AAA error handling and correct loop placement of subscriber versus dependent information.

Read more on the 270/271 Eligibility & Benefits Verification page.

Why do eligibility rejections turn into claim denials?

Because AAA rejections are frequently misread as coverage determinations. An AAA 72 routed into the same workflow bucket as inactive coverage converts a correctable data error into a self-pay determination or a claim submitted to the wrong payer. Separating inquiry failures from coverage findings is the single highest-yield change most organizations can make to eligibility workflow.

Read more on the 270/271 Eligibility & Benefits Verification page.

Does Medicare eligibility work the same way?

Medicare eligibility runs through HETS rather than a commercial endpoint and requires an approved trading-partner relationship. A HETS trading-partner attestation requirement took effect May 11, 2026. Organizations accessing HETS through an intermediary should confirm their own attestation posture rather than assume it is covered.

Read more on the 270/271 Eligibility & Benefits Verification page.

What is the difference between a 277 and a 277CA?

The 277 is a response to a 276 inquiry about a claim already in adjudication. The 277CA is an unsolicited Claim Acknowledgment reporting whether the payer's front-end edits accepted the claim for adjudication at all. A claim rejected at 277CA will never return a meaningful 277 status because it isn't in the queue.

Read more on the 276/277 Claim Status page.

Why is our claim status inquiry volume so high?

Usually because the acknowledgment chain isn't being consumed. If you process 999 and 277CA results, you know which claims are actually in adjudication and approximately when an 835 should follow, which turns status inquiry into an exception tool rather than a daily sweep.

Read more on the 276/277 Claim Status page.

What is an X12 278 transaction?

The 278 is the HIPAA-standard health care services review transaction: prior authorization. The 278 Request carries the requester, subscriber, patient, requested service and dates, and servicing provider. The 278 Response returns the payer's certification action (certified in total, certified partial, pended, or denied) with a certification number when granted. The mandated version is 005010X217.

Read more on the 278 Prior Authorization page.

Does CMS-0057-F eliminate the X12 278?

No. CMS-0057-F requires impacted payers to implement a FHIR-based Prior Authorization API in addition to the existing X12 278, which remains the HIPAA standard transaction. Both paths will coexist. Organizations should plan for dual-path operation rather than a migration.

Read more on the 278 Prior Authorization page.

When is the CMS-0057-F prior authorization deadline?

API compliance dates begin January 1, 2027. Material citing January 2026 is incorrect. The rule also carries separate obligations on decision timeframes and denial reason specificity that are distinct from the API requirements.

Read more on the 278 Prior Authorization page.

Why is prior authorization still manual if the 278 has existed for decades?

Because the clinical justification a payer needs (chart notes, imaging, conservative treatment history) has no natural home in the 278. The 275 attachment transaction is the intended solution, but payer adoption is uneven and requirements vary by payer and service. The obstacle is variance in what payers accept rather than the absence of a standard.

Read more on the 278 Prior Authorization page.

What does a pended 278 response mean?

Pended means the payer has neither certified nor denied; it needs more information or more time. Pended authorizations account for most of the administrative burden in prior authorization, because they have no deterministic resolution date and require a documentation round-trip. Workflows that stop reading after the first 278 Response are handling only the easy half.

Read more on the 278 Prior Authorization page.

How does the 275 relate to the 278?

The 275 carries additional documentation supporting a prior authorization request, linked to its parent 278 by control number. It is the standards-based path for getting clinical justification to the payer without a fax. Payer support and documentation requirements vary.

Read more on the 278 Prior Authorization page.

What is an X12 275 transaction?

The HIPAA-standard transaction for submitting additional documentation (operative reports, labs, chart notes) supporting a claim (837) or a prior authorization request (278), linked to its parent by control number.

Read more on the 275 Claims Attachments page.

Why do 275 attachments fail?

Linkage. If the control number doesn't match what the payer expects, the documentation arrives unassociated and the claim denies for missing documentation that was actually sent. The failure is silent from the sending side.

Read more on the 275 Claims Attachments page.

What is an HL7 Z-segment?

A locally defined segment HL7 v2 permits organizations to add for data the standard doesn't cover. Z-segments are non-standard by definition and their meaning exists only in the sending organization's documentation. They are heavily used, which is why an HL7 integration is a relationship with a specific sender rather than an implementation of a specification.

Read more on the HL7 Integration page.

Why is translating HL7 to X12 difficult?

Because they model different things. HL7 v2 describes clinical events; X12 describes what is being billed and to whom. The mapping requires decisions about intent, beyond field correspondence, and those decisions should live somewhere documented and auditable rather than inline in an interface engine.

Read more on the HL7 Integration page.

Does FHIR replace X12 EDI?

No. The X12 transactions (837, 835, 270/271, 278) remain the HIPAA standard transactions. FHIR is additive, including under CMS-0057-F. Both paths will coexist for years and organizations will need to operate against whichever a given payer supports.

Read more on the FHIR API Integration page.

Why do FHIR API projects fail?

Rarely on endpoint construction, which is a known quantity. Usually because the source data doesn't exist in a form the API can serve at the completeness the profile requires, or because identity and consent decisions were deferred until after endpoints were written and then forced a rebuild.

Read more on the FHIR API Integration page.

When is the CMS-0057-F API deadline?

CMS-0057-F, the CMS Interoperability and Prior Authorization Final Rule, requires impacted payers to implement FHIR-based Patient Access, Provider Access, Payer-to-Payer, and Prior Authorization APIs. API compliance dates begin January 1, 2027.

Read more on the FHIR API Integration page.

Workflows

36 questions
What is a clearinghouse alternative?

A clearinghouse alternative performs the same functions as a traditional healthcare clearinghouse (translation, validation and routing of HIPAA X12 transactions) using an architecture that does not retain PHI in a central repository. PNT processes 837, 835, 270/271, 276/277, 278 and 275 transactions and retains no PHI at rest.

Read more on the Clearinghouse Alternative page.

Can I switch clearinghouses without disrupting cash flow?

Yes, if the migration is run in parallel. The standard approach is to run both paths simultaneously for a defined period, comparing acknowledgments and remittances transaction by transaction before cutting over. The timeline is driven primarily by per-payer enrollment requirements, not by technical integration. EFT and ERA enrollment is governed separately under the CAQH CORE EFT & ERA Enrollment Data Rule and often runs longer than claims enrollment.

Read more on the Clearinghouse Alternative page.

What is the difference between a clearinghouse and a data sharing authority?

A clearinghouse translates and routes transactions and retains them in a central repository. A data sharing authority performs the same translation and routing but does not take ownership of or retain the underlying data. The functional service is equivalent; the difference is whether a repository of your historical PHI exists at the intermediary.

Read more on the Clearinghouse Alternative page.

Does zero-residency mean you can't resend a transaction?

It means resend cannot be served from a retained payload. Status and provenance metadata are retained; the transaction content is not. In practice a resend is initiated from the submitter's own system, which is the authoritative copy in any case. Organizations that rely on their clearinghouse as their system of record should understand they are also relying on it as their breach surface.

Read more on the Clearinghouse Alternative page.

Is a clearinghouse alternative HIPAA compliant?

HIPAA mandates the use of standard transaction formats and imposes Security Rule obligations on covered entities and business associates. It does not require an intermediary to retain data. An architecture that retains nothing reduces, rather than creates, Security Rule exposure: there is no repository of PHI at rest to safeguard.

Read more on the Clearinghouse Alternative page.

What is coverage discovery?

Coverage discovery identifies active insurance coverage a provider has no record of, using demographics rather than a member identifier as the entry point. It applies after self-pay registration, emergency encounters with incomplete demographics, or an AAA 72 rejection that correction could not resolve.

Read more on the Coverage Discovery page.

How is coverage discovery different from eligibility verification?

Eligibility verification confirms whether coverage already on file is active, using a 270 directed at a known payer. Discovery finds coverage you don't know about, searching across payers rather than querying one. A 270 cannot perform discovery because it requires you to already know which payer to ask.

Read more on the Coverage Discovery page.

When should you run coverage discovery?

After a self-pay registration, after an emergency or incomplete registration, and after an AAA 72 that re-inquiry with corrected demographics did not resolve. Each of these commonly produces an incorrect self-pay determination that surfaces later as bad debt.

Read more on the Coverage Discovery page.

What is coordination of benefits?

COB determines which payer pays first when a member has more than one coverage. The order is set by rule, NAIC model rules for common commercial cases, adopted with state variation, regardless of patient preference or which card was presented first.

Read more on the Coordination of Benefits page.

What is Medicare Secondary Payer (MSP)?

MSP rules determine when Medicare pays secondary to another payer, covering situations including working aged, disability with a large group health plan, ESRD coordination periods, workers' compensation, liability, and no-fault. Each has distinct criteria and time boundaries. MSP reason codes on the 835 report the payer's determination.

Read more on the Coordination of Benefits page.

Why do COB errors surface so late?

Because they rarely fail at registration. They surface as a denial months later or as a recovery demand a year later. A recovery is worse than a denial, because the money was already posted and spent. That lag is why COB accuracy is chronically under-invested relative to its cost.

Read more on the Coordination of Benefits page.

What is EFT/ERA reassociation?

Matching an ACH healthcare payment to its corresponding X12 835 remittance by comparing the reassociation trace number in the ACH CCD+ addenda record to the TRN02 element of the 835. A successful match enables automated posting; a failure sends the payment to manual reconciliation.

Read more on the EFT/ERA Reassociation page.

Why does reassociation fail so often?

Five common causes: the bank does not pass the CCD+ addenda to the depositor; one EFT covers multiple 835s or vice versa; trace value formatting drifts between the banking and EDI paths; payment and remittance arrive days apart; and payer TRN02 practice varies from the operating rule.

Read more on the EFT/ERA Reassociation page.

Do you have to store remittances to automate posting?

No. Reassociation is a comparison of two identifiers. The payload does not need to be retained for the match to occur, and the receiving organization's system remains the system of record for the remittance itself.

Read more on the EFT/ERA Reassociation page.

Why do some payers still send paper remittance?

Usually enrollment rather than capability. EFT and ERA enrollment is governed by the CAQH CORE EFT & ERA Enrollment Data Rule but remains payer-by-payer and form-by-form in practice. Incomplete enrollment is the common reason an organization is electronic with some payers and paper with others.

Read more on the EFT/ERA Reassociation page.

What are CARC and RARC codes?

Claim Adjustment Reason Codes state why a payment differs from the billed amount. Remittance Advice Remark Codes supply supplemental explanation. Both are carried in the X12 835 and together form the payer's structured account of its adjudication decision, the basis for any appeal.

Read more on the Denial Management page.

How do you reduce claim denials?

Separate prevention from management. A large share of denials are predictable at submission (implementation guide non-conformance, known payer edits, misread eligibility rejections, wrong COB order) and should be caught before transmission. What remains is the genuine appeal population, which is smaller and more worth working.

Read more on the Denial Management page.

Why do denials often have upstream causes?

Because the failure and the symptom are separated by time and workflow. An AAA 72 misread as inactive coverage becomes a claim to the wrong payer and then a denial. A secondary claim that did not carry the primary 835's adjustment data forward presents as a coding denial. Working the denial rather than the cause guarantees the denial recurs.

Read more on the Denial Management page.

Why do secondary claims get denied after the primary paid?

Usually because the primary's payment and adjustment data from the 835 was not carried forward accurately into the secondary 837. The second payer rejects on what it sees, amounts that don't reconcile or adjustment codes that don't make sense, so the denial presents as a coding problem while the cause is a data carry-forward failure.

Read more on the Secondary Claims page.

What data does a secondary claim need from the primary?

Paid amounts, CARC adjustment detail, and patient responsibility from the primary's 835, mapped into the secondary 837's COB segments. If the primary 835 was parsed incorrectly, or the COB order was wrong to begin with, the secondary claim cannot be correct regardless of coding.

Read more on the Secondary Claims page.

Why does secondary AR age differently?

Because secondary claims have three silent upstream dependencies, the 835 parse, the adjustment mapping, and the COB determination, each of which fails without an obvious signal. The denial appears far from its cause, so resubmission at face value tends to fail the same way.

Read more on the Secondary Claims page.

How do you automate prior authorization?

By handling the pended queue as well as the request and response. Certified and denied resolve themselves; pended authorizations have no deterministic resolution date and require a documentation round-trip, which is where the administrative burden actually sits. Automation that stops at the first response has automated the cheap half.

Read more on the Prior Authorization Modernization page.

Should we build for X12 278 or the CMS-0057-F FHIR API?

Both. CMS-0057-F requires impacted payers to expose a FHIR Prior Authorization API beginning January 1, 2027, but does not retire the X12 278, which remains the HIPAA standard transaction. Payers will move at different times. A single workflow surface above both paths is the architecture that survives.

Read more on the Prior Authorization Modernization page.

Why is prior authorization still done by fax?

Because the clinical justification a payer needs has no natural home in the 278, and payer support for the 275 attachment transaction is uneven: different payers accept different documentation with different linkage conventions. The obstacle is variance in what payers accept; the standard itself exists.

Read more on the Prior Authorization Modernization page.

What is CMS-0057-F payer-to-payer exchange?

A requirement that impacted payers exchange a member's clinical and administrative data when the member changes plans, conditioned on member opt-in, via a FHIR API. Compliance dates begin January 1, 2027.

Read more on the Payer-to-Payer Interoperability page.

Why is payer-to-payer the hardest CMS-0057-F requirement?

Because it requires two organizations with no commercial relationship to find each other, authenticate each other, and match a member across systems using different identifiers, none of which the API solves. Building the endpoint is the easy part. Discovery, trust, and identity matching depend on parties outside your control.

Read more on the Payer-to-Payer Interoperability page.

Is member opt-in just a consent checkbox?

No. It requires capturing consent, retaining evidence of it, honoring its scope, and handling withdrawal, at enrollment and at population scale. Programs that scope it as a UI element find the operational shape of it in production.

Read more on the Payer-to-Payer Interoperability page.

What is Medicaid reclamation?

The process by which a state Medicaid agency recovers payments it made where a third party was liable. Medicaid is the payer of last resort, so where other coverage existed and Medicaid paid, the state has a recovery right. Accuracy depends on coverage identification and COB data quality.

Read more on the Medicaid Reclamation page.

Why does contingency pricing create a problem in reclamation?

Because a vendor paid a percentage of recoveries has no cost for a wrong assertion and lost revenue for a missed one. That asymmetry biases toward aggressive assertion, which produces disputes, reversals, and provider abrasion, costs that do not appear in the recovery number the vendor is measured on.

How are reclamation, coverage discovery, and COB related?

They are the same data problem at three points in time: before the claim (discovery), at the claim (COB), and after the payment (reclamation). Treating them as three separate programs with three vendors reliably produces three inconsistent answers about the same member.

What is the HETS trading partner attestation requirement?

CMS requires organizations accessing Medicare eligibility through the HIPAA Eligibility Transaction System to hold an approved trading-partner relationship and attest to the terms of that access. The attestation requirement took effect May 11, 2026.

Read more on the HETS Attestation page.

If we access HETS through a vendor, are we covered?

Verify rather than assume. Many organizations reach HETS through an intermediary and assume the vendor's posture covers them. Confirm your own attestation obligation against current CMS documentation rather than inheriting a vendor's characterization of it, including ours.

What is MBI lookup?

Retrieval of a beneficiary's current Medicare Beneficiary Identifier when it is unknown or has changed. The MBI replaced the SSN-based HICN. It is a capability adjacent to eligibility verification with its own access considerations.

Where does revenue cycle leakage actually come from?

Predominantly from transaction-level failures rather than workflow design: eligibility rejections misread as coverage determinations, claims rejected at 277CA that nobody consumes, EFT payments that never reassociate to their 835, and COB errors that surface months later. Each is usually owned by a different team and none is measured as transaction quality.

Is it better to prevent denials or manage them?

Prevent the predictable ones. Implementation guide non-conformance and known payer edits are knowable before transmission; catching them at ingestion turns a rework cycle into a keystroke. What remains after prevention is the genuine appeal population, which is smaller and worth skilled attention.

What denial rate should we expect?

There is no useful general answer. Denial rates, clean claim rates, and AR days vary enormously by specialty, payer mix, and how an organization defines the metric. Any vendor quoting a benchmark improvement without reference to your baseline is quoting marketing.

What do health plans need for CMS-0057-F?

Four FHIR APIs, Patient Access, Provider Access, Payer-to-Payer and Prior Authorization, with compliance dates beginning January 1, 2027. Payer-to-payer is the hardest because it requires discovery, trust and member matching with organizations outside your control.

How do health plans reduce data intermediary risk?

By asking whether the intermediary needs to retain the data at all. Encryption and access controls protect a repository that still exists. An intermediary architected to retain nothing removes the repository, which bounds the blast radius of its compromise to transactions in flight.

Do providers have to comply with CMS-0057-F?

No. The rule obligates payers: Medicare Advantage, Medicaid and CHIP plans, and FFE QHP issuers. Providers have no deadline. A vendor selling a provider organization CMS-0057 compliance is selling a deadline that does not exist.

What happens to a provider when its clearinghouse is breached?

Typically claims, eligibility, and remittance stop, because the system that held the data is the system that moved it. The event is simultaneously a privacy exposure and a cash flow interruption, affecting every connected organization at the same time.

What should an RCM company ask its clearinghouse?

Where does our clients' data end up, who else holds a copy, and what is the blast radius of your compromise? Your clients' due diligence is increasingly asking you the same question, and the answer that survives it is architectural rather than contractual.

Does HETS attestation apply to RCM companies?

If you touch Medicare eligibility through HETS, the trading-partner attestation requirement effective May 11, 2026 is relevant to you. Confirm your own posture against current CMS documentation rather than assuming an intermediary covers it.

What data handling questions do TPA clients ask?

Increasingly: who holds our members' data, how many copies exist, and what happens if your vendor is breached. An intermediary that retains nothing removes a party from that answer.

Why is COB especially relevant for TPAs?

Self-funded populations frequently carry multiple coverages, and COB errors surface late, as denials months later or recovery demands a year later. Coverage discovery and COB accuracy are the same investment viewed at different points in time.

Is PNT Data a small business contractor?

PNT Data Corp. is a verified Service-Disabled Veteran-Owned Small Business (SDVOSB).

Do state Medicaid programs have CMS-0057-F obligations?

Yes. State Medicaid and CHIP fee-for-service programs and Medicaid and CHIP managed care plans are among the impacted payers, with API compliance dates beginning January 1, 2027.

Can we add EDI connectivity without storing PHI?

Yes. Routing, validation, and translation are operations on a transaction in transit. Storing it in your platform is an implementation choice rather than a requirement, and it is a choice whose exposure multiplies with every customer you add.

How do we give customers transaction visibility without retaining their data?

Visibility questions are answered with metadata: identifiers, timestamps, state transitions, outcomes. None of them require the payload.
