Investigate an Unbilled ABA Service Without Auto-Creating a Claim

Define Wesley's unbilled-service investigation control

Wesley's decision file begins with an exception signal, not a presumed missing charge. It distinguishes service performed, documentation pending, nonbillable work, duplicate signal, canceled visit, claim already created, payer hold, and expired or unresolved route.

Build the unbilled service decision file

Record exception source; person; scheduled event; actual service; record; author and completion; provider; setting; code candidate; time and units; billability; authorization; payer; enrollment; prior claim; filing clock; hold; exclusion; correction; approval; owner; and close. Structured fields preserve identity, authority, source, version, clock, evidence, calculation, money movement, action, hold, retest, and closure. Narrative captures clinical meaning, uncertainty, disagreement, accessibility, family communication, legal deferral, and each accountable owner's rationale.

Run Wesley's workflow

Wesley verifies occurrence and record integrity before any coding step. A qualified reviewer maps the service to current coding and payer sources. The release owner checks for an existing or competing claim and preserves the original exception.

Assign decisions to qualified owners

An empty claim field does not prove missed revenue. Some documented work is bundled, administrative, noncovered, already billed, or outside the permitted billing path.

Work through Wesley's fictional example

Wesley reviews 25 fictional signals. Ten are valid unbilled services, five are documentation pending, three are nonbillable activities, two are cancellations, two already have claims, one is a duplicate signal, one is outside timely filing, and one remains unclear. Twenty-four receive dispositions. One stays held. This synthetic cohort tests control logic and arithmetic only. It creates no coding, coverage, authorization, payment, client-balance, refund, recovery, overpayment, accounting, disclosure, or legal conclusion for a real person, provider, payer, claim, contract, or account.

Calculate Wesley's measures

Disposition completeness is 24 of 25 signals, or 96.0%. Valid-unbilled incidence is 10 of 24 reviewed signals, or 41.7%, and cannot be applied to the unresolved item or all services.

Address the main unbilled-service investigation risk

Automated claim creation can bill canceled or unsupported visits. Deleting exceptions that are not billable can hide recurring scheduling or documentation defects.

Test the unbilled service decision file against exceptions

Wesley tests completed service, unsigned note, admin meeting, bundled work, cancellation, duplicate signal, existing claim, authorization gap, filing expiry, and corrected record. Each fixture retains source version, expected state, actual state, affected unit, safeguard, owner, repair, retest, and disposition. Failed, unknown, quarantined, pending, excluded, and held items remain in the predeclared cohort.

Document the stop condition

Do not create a claim when service, record, coding, payer, authorization, provider, or deadline evidence is unsupported. Route urgent filing clocks to the accountable owner.

Hand off open work with evidence

Wesley's handoff includes the signal, source service evidence, applicable gates, prior claim search, clock, disposition, prohibited action, and owner.

Communicate the current state accurately

Questions to clinicians identify the exact service and missing fact without asking them to alter judgment or add unsupported time. Families are contacted only through the appropriate process.

Verify Wesley's acceptance evidence

A reviewer recreates the disposition from raw evidence and verifies that every released claim matches the actual service. Held and excluded signals remain queryable.

Maintain Wesley's control over time

Wesley reviews signal precision and source causes monthly. False positives, late records, payer holds, and true misses drive separate improvements rather than one broad billing reminder.

Monitor Wesley's operational results

The practice measures unbilled signals by source, age, disposition, payer, provider role, and period of service. It reports both the original signal count and the verified unbilled count. Claim dollars are shown only after an approved claim exists, while potential amounts remain labeled estimates with source and assumptions.

Set a maturity rule for every signal source. A service can remain pending while the ordinary documentation or review window is open, then enter the investigation cohort when that window closes. The investigator records whether the service occurred, whether the record supports the reported facts, which qualified role decided billability, and which payer prerequisites apply. Automation may assemble evidence and calculate age. It should leave claim creation blocked until those decisions are complete and should preserve excluded, corrected, and still-open signals for later audit.

Run Wesley's independent review

Wesley assigns a reviewer who did not build the unbilled service decision file. The reviewer reconstructs the unbilled-service investigation source, state, calculation, money movement, action, and close. Earlier versions, failed tests, unknowns, credits, exclusions, pending items, and holds remain available. Hidden exceptions, missing authority, unexplained amounts, overwritten history, or unsupported financial action fail review.

Anchor released claims to the adopted standard

Current 45 CFR 162.1102 identifies the adopted professional-claim standard. Wesley preserves exact service and claim identities throughout the unbilled service decision file. A financial estimate, schedule, or rate table never substitutes for the transaction or source record.

Separate front-end claims evidence from adjudication

The CMS electronic-claims page describes a Medicare route with batch and claim edits. The CMS remittance page separates claim, line, provider adjustment, and payment information. Wesley keeps those Medicare examples scoped while verifying each payer's current route for unbilled-service investigation.

Use fee schedules within their stated scope

The CMS PFS overview says its tool provides Medicare payment information and directs users to the MAC for official definitive files. The 2026 national payment file page exposes versioned Medicare files. Wesley does not treat either source as a commercial contract or universal ABA rate.

Keep credit-balance pathways program-specific

The CMS-838 instructions define a Medicare credit-balance reporting mechanism and explicitly distinguish amounts due to Medicare, another insurer, or a patient. Wesley uses that lesson to classify recipients while verifying actual entity, program, payer, contract, state, and account duties.

Escalate potential overpayments through current authority

Current 42 CFR 401.305 governs specified Medicare overpayments and includes identification, investigation, deadline, reporting, and lookback provisions. Wesley does not generalize that rule to every credit, refund, payer, or client account and routes legal conclusions to qualified owners.

Interpret adjustment codes with the complete remittance

The X12 external-code-list index defines code-list scopes. Wesley reads group codes, CARCs, RARCs, provider adjustments, and payment evidence with the full claim and payer context before deciding unbilled-service investigation.

Protect payment and account information

HHS payment guidance and minimum-necessary guidance apply when their HIPAA conditions are met. Wesley limits access and disclosure to the approved purpose and recipient while preserving evidence for the unbilled service decision file.

Keep clinical and compliance authority visible

The CASP public summary and BACB Ethics Code retain their stated scopes. The voluntary OIG GCPG is a compliance framework rather than a payer or accounting rule. Wesley keeps clinical, billing, contract, payer, accounting, privacy, compliance, and legal decisions with qualified owners.
