Clean claim
A clean claim carries everything a payer needs to adjudicate it on first submission — no missing data, no manual intervention, no request for more information.
Updated
A clean claim is a claim submitted with complete, accurate information — correct patient and coverage data, valid codes, any required attachments, and submission within the payer’s timely-filing window — so the payer can process it without returning it for correction or additional information.
The clean-claim rate (also called the first-pass acceptance rate) — the share of claims accepted on first submission — is a core revenue-cycle performance measure.
Medicare defines the term for its own prompt-payment rules: a clean claim is one with “no defect or impropriety (including any lack of required substantiating documentation) or particular circumstance requiring special treatment that prevents timely payment”. A payer’s contract may define it differently, so the definition that governs a given claim is that payer’s.
In practice
Every claim that pays on first pass avoids the cost of rework, resubmission, or appeal, which is why the clean-claim rate is tracked as a revenue-cycle measure in its own right — HFMA publishes it as MAP Key CL-1.
Commonly confused with
- Rejected claim: A rejection fails a front-end edit before the payer adjudicates it — it never entered the payer’s system.
- Denied claim: A denial is a claim the payer adjudicated and then refused to pay.
