What Is Clean Claim?
A clean claim is a properly completed claim that requires no additional information from the provider or a third party and no special handling, so the payer can accept it into adjudication without manual intervention. Clean means accepted for processing — not paid.
- Track CCR monthly by payer and by service line; outliers point at a specific workflow rather than a general quality problem.
- No free primary source publishes a clean-claim-rate target, so the honest version is the blank: set your own floor from your own trailing twelve months, then move it.
- Read CCR next to First-Pass Resolution Rate rather than alone — a rising CCR against a flat FPRR means the edits are catching format errors while adjudication denials go unworked.
Clean Claim
Also known as: Clean Submission; First-pass Claim
A clean claim is a properly completed claim that requires no additional information from the provider or a third party and no special handling, so the payer can accept it into adjudication without manual intervention. Clean means accepted for processing — not paid.
Definition
Medicare's statutory definition, at 42 U.S.C. § 1395u(c)(2)(B), is a claim "that has no defect or impropriety (including any lack of any required substantiating documentation) or particular circumstance requiring special treatment that prevents timely payment from being made on the claim under this part." Medicaid's regulatory definition, at 42 CFR 447.45(b), is "one that can be processed without obtaining additional information from the provider of the service or from a third party" — and it expressly excludes a claim from a provider under investigation for fraud or abuse, and a claim under review for medical necessity. State prompt-pay laws work the same way: the payment clock starts on receipt of a clean claim, so a claim that is not clean never starts it. The Clean Claim Rate (CCR) built on that definition has a precise shape. NUMERATOR: claims accepted into adjudication on first submission — passing the scrubber, the clearinghouse and the payer's front-end edits with no rejection and no request for additional information. DENOMINATOR: all claims submitted in the period. EVENT: acceptance into adjudication, not payment. PERIOD: monthly, dated by submission; CCR is readable within days because it does not wait for the claim to adjudicate. That is a different event from the one First-Pass Resolution Rate measures. 'Passes edits' and 'paid on first submission' are not interchangeable: a clean claim has been accepted for adjudication, and it can still be denied on adjudication for eligibility, coverage, prior auth or medical necessity.
Example
A claim with patient name, DOB, member ID, group number, NPI, taxonomy, valid CPT/ICD-10/POS, correct modifier usage, valid prior-auth number (where required), and no syntactic EDI errors is accepted into adjudication without a request for more information — that is a clean claim. A claim missing the rendering NPI, with mismatched DOB, or with a deleted CPT code is not clean.
Common Misconceptions
Clean claim does not mean 'paid claim'. A clean claim has passed edits and been accepted into adjudication; it can still be denied for medical necessity, eligibility, coverage or prior auth. Clean Claim Rate measures acceptance into adjudication; First-Pass Resolution Rate measures payment on first submission. They answer different questions and will not match — a practice with a high CCR and a low FPRR has a payer-adjudication problem, not a scrubber problem. Note too that 'clean' is a payer-facing test, not an internal one: a claim your own scrubber passes is only clean once the payer's front-end edits accept it.
Practical Application
Track CCR monthly by payer and by service line; outliers point at a specific workflow rather than a general quality problem. Do not anchor on the "98%% clean claim rate" that circulates as an industry standard — it traces to a vendor-sponsored article that in turn attributes it to a trade publication, with no methodology at any link in the chain, and HFMA's MAP Keys publish metric definitions rather than target values. No free primary source publishes a clean-claim-rate target, so the honest version is the blank: set your own floor from your own trailing twelve months, then move it. Read CCR next to First-Pass Resolution Rate rather than alone — a rising CCR against a flat FPRR means the edits are catching format errors while adjudication denials go unworked.

Claim Scrubbing
Claim scrubbing is the automated pre-submission process that runs claims through a rule-set of payer-specific and standards-based edits (NCCI, MUE, HIPAA syntax, payer policies) to identify and correct errors before the claim leaves the practice.

First-Pass Resolution Rate is the percentage of claims paid on first submission — no rejection, no denial, no corrected claim and no appeal — measured against every claim submitted in the period. Its complement is rejections plus denials, not denials alone.
Read definitionAdjudication
Adjudication is the payer-side process of reviewing and determining how a claim will be paid: applying eligibility, benefits, coverage rules, contracted rates, and edits to determine the allowed amount, paid amount, patient responsibility, and any denials or adjustments.
