Claim

A claim is a request built from source evidence

The CMS Uniform Glossary defines a claim as a request for a benefit, including reimbursement of a health care expense, made by a person or provider to a plan for items or services believed to be covered. The glossary is educational and says plan terms govern when definitions differ.

For a provider, the claim should represent care actually delivered and supported by the completed record. It is neither the clinical note nor the provider's family bill. It selects and arranges facts from approved sources into the payer's required format.

Common claim sources include:

• member and product data from current eligibility evidence
• billing, rendering, referring, ordering, and service-location identities from applicable enrollment, contract, roster, and source records
• actual date, time, place, modality, and person delivering service from the clinical and scheduling records
• procedure, modifier, unit, and diagnosis choices from current code sets, payer rules, and a documented coding decision
• authorization reference and limits from the payer decision
• charge from the practice's approved fee record

Each field needs an owner and provenance. A copied prior claim can speed entry while creating stale member, provider, date, authorization, or code data.

Authorization, claim, and payment are separate states

Prior authorization is a payer decision about a proposed service under specified conditions. The claim reports what occurred. Adjudication applies benefit, contract, coding, and payment rules to the submitted claim. A remittance or EOB explains the result. An electronic funds transfer or check moves money.

A claim may have authorization and still fail another rule. A technically complete claim may reach adjudication and receive a coverage denial. A paid claim can later be adjusted or recouped. Keep these states separate:

1. created from reviewed evidence
2. held or released by local validation
3. transmitted to a named receiver
4. acknowledged or rejected by the applicable intermediary or payer
5. accepted for adjudication
6. adjudicated as paid, denied, or otherwise adjusted
7. remitted, paid, posted, and reconciled

The words “submitted,” “accepted,” and “paid” should each identify the sender, receiver, artifact, and date.

Professional claims can be electronic or paper

The manifest-provided CMS Electronic Billing and EDI page describes electronic transactions between providers, clearinghouses, billing services, Medicare, and other plans. It is Medicare-oriented guidance rather than one universal payer workflow.

CMS's professional claim page identifies 005010X222A1 as the current adopted professional 837 implementation for covered electronic professional claims and explains front-end edits, claim-level rejection, and later coverage or payment edits in Medicare's route. The CMS-1500 is the corresponding professional paper form for permitted paper submission. A paper field instruction should not be copied into an 837 without the electronic standard and receiver guide.

Licensed CPT and X12 materials have their own terms. A payer companion guide can clarify the receiver's route while remaining subordinate to the adopted standard. Verify both.

Clinical and billing corrections preserve history

A clinician makes any permitted late entry, amendment, or correction to the clinical record under the documentation policy, preserving authorship, dates, original content, and reason. A qualified coding or billing reviewer determines the claim change from verified evidence.

Use the payer's defined corrected-claim, replacement, void, appeal, or resubmission route. Preserve the original claim, control numbers, acknowledgments, reason codes, changed fields, decision maker, transmission, and final disposition. Replacing a denied claim with a duplicate original can create another problem.

A fictional claim batch

A fictional practice prepares 24 professional claims containing 63 service lines. Local validation holds three claims because the rendering-provider configuration, authorization reference, or unit evidence is incomplete. Therefore, 21 of 24 claims, or 87.5%, are released for transmission.

The clearinghouse's named claim-level report marks 20 as forwarded and one as rejected. Clearinghouse yield is 20 of 21, or 95.2%. The payer later acknowledges 18 of those 20 claims for adjudication and rejects two. Original-batch-to-payer-intake yield is 18 of 24, or 75%.

The six claims outside payer intake remain visible: three local holds, one clearinghouse rejection, and two payer rejections. The 63 service-line denominator stays separate from every claim-level percentage.

After adjudication, the CMS remittance guidance illustrates how a Medicare ERA or paper remit reports claim and line decisions, adjustment reasons, and amounts. Other payers may use different artifacts. Match the remittance to the original claim and the actual payment.

Measure a mature claim cohort

Useful measures include local release yield, rejection rate by receiver, payer-intake yield, first-pass adjudication yield, denial rate, days to adjudication, payment posting accuracy, and unresolved adjustment age. Define claim versus line units and use one maturity window for each outcome.

Track authorization, clean-claim status, claim acceptance, adjudication, member responsibility, and payment as separate fields. A favorable result in one field supplies no automatic result in another.
