What Is First-Pass Resolution Rate?
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.
- Track FPRR by payer and by service line, and split the complement into rejections and denials before working it.
- A rejection is a data defect that can be corrected and resubmitted as a new claim, often the same day; a denial is a payment determination that needs a documented appeal inside the payer's window.
- Every rework cycle adds days to A/R and consumes labor, so the split decides where the labor goes and which team owns the fix.
First-Pass Resolution Rate
Also known as: FPRR; First-Pass Acceptance Rate; First-Pass Yield; First-Pass Claim Approval Rate; First-Pass Denial Rate (inverse metric)
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.
Definition
NUMERATOR: claims that reached a paid final status on the original submission — no clearinghouse or payer front-end rejection, no denial, no corrected claim, no resubmission, no appeal. DENOMINATOR: every claim submitted in the period. EVENT: the outcome of the first submission. PERIOD: claims submitted in the period, measured after enough lag for them to finish adjudicating — a rolling 90–180 days is the usual operating choice. FPRR is not the Clean Claim Rate. CCR measures whether a claim was accepted into adjudication; FPRR measures whether that claim was then paid without rework. A claim can pass every edit and still be denied for eligibility, prior auth or medical necessity, which fails FPRR while leaving CCR untouched. The complement is where published analysis usually goes wrong: 100% − FPRR is not the denial rate. It is rejections plus denials plus anything that paid only after a corrected claim or an appeal. A rejection is returned before adjudication — in Medicare's own words, a claim returned as unprocessable "doesn't meet the criteria to be considered as a claim, is not denied, and, as such, is not afforded appeal rights" (CMS, Medicare Billing: CMS-1500 & 837P course glossary) — while a denial is a payment determination the payer made and that can be appealed. The two have different owners, different fixes and different cycle times, so a first-pass shortfall has to be split before it can be worked. The 95%+ figure widely quoted as best-in-class is an operating target, not a measured benchmark; no free primary source publishes an observed FPRR distribution for physician practices.
Example
A practice submits 10,000 claims in a quarter. 9,200 are paid on first submission, 600 are adjudicated and denied, and 200 are rejected before adjudication — at the clearinghouse or in the payer's front-end edits. FPRR = 9,200 ÷ 10,000 = 92%. The 8% complement is not 8% payer denials: on the same 10,000 submitted claims it is a 6% denial rate (600 claims) and a 2% rejection rate (200 claims). Only the 600 are payer payment determinations carrying appeal rights; the 200 are corrected and resubmitted as new claims.
Common Misconceptions
FPRR is not the same as Clean Claim Rate. A high CCR (claims passing scrubber and EDI edits) can sit well above a materially lower FPRR, because accepted claims still deny on adjudication for eligibility, medical necessity or prior auth. The second misconception is arithmetic: the complement of FPRR is routinely reported as the denial rate. It is not. It bundles rejections, which never reached adjudication, with denials, which did. Report the two separately, or the denial rate is overstated and the front-end rejection problem stays invisible.
Practical Application
Track FPRR by payer and by service line, and split the complement into rejections and denials before working it. A rejection is a data defect that can be corrected and resubmitted as a new claim, often the same day; a denial is a payment determination that needs a documented appeal inside the payer's window. Every rework cycle adds days to A/R and consumes labor, so the split decides where the labor goes and which team owns the fix.
Related Terms
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.
Read definitionDenial Rate
Denial Rate is the percentage of claims (or claim dollars) denied by payers on initial adjudication, calculated as Denied Claims ÷ Total Claims Adjudicated × 100, typically tracked monthly and segmented by payer and denial reason category. Claims rejected before adjudication sit in neither the numerator nor the denominator — a rejection is not a denial.
Read definitionClaim 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.
Read definitionDays in A/R
Days in A/R is total accounts receivable divided by average daily charges over a chosen period — this page uses a 90-day rolling window — and represents the average number of days it takes a practice to collect on a billed charge.
