First-pass resolution rate (FPRR) is the percentage of claims that get paid on the very first submission, with no rejection, denial, or rework. It is calculated by dividing the number of claims paid on first submission by the total number of claims submitted, multiplied by 100. A high FPRR means your billing process is catching problems before payers do; a low FPRR means your team is doing the same work twice and your cash is arriving late.
How do you calculate first-pass resolution rate?
The formula is straightforward:
FPRR = (claims paid on first submission ÷ total claims submitted) × 100
Count a claim as “first-pass resolved” only if it was adjudicated and paid without being rejected by a clearinghouse, denied by the payer, or returned for correction. Claims that eventually get paid after an appeal or resubmission still represent rework — they should not count toward the numerator, even though they end up in your collections total.
What is a good first-pass resolution rate?
Commonly cited industry targets put a healthy FPRR at 90% or above, with high-performing billing operations pushing into the mid-90s. If your rate sits meaningfully below that range, a share of your revenue is riding on second and third attempts — each with added labor cost, payment delay, and a real chance of never being collected at all, since untouched denials frequently go unworked.
How is FPRR different from clean claim rate?
The two are related but measure different points in the claim’s life:
| Metric | What it measures | Where problems show up |
|---|---|---|
| Clean claim rate | Claims submitted without errors that would cause a rejection or edit | Front-end: registration, eligibility, coding, charge entry |
| First-pass resolution rate | Claims actually paid on the first submission | End-to-end: everything the clean claim rate catches, plus payer-side denials like medical necessity, authorization, and timely filing |
A practice can submit technically “clean” claims that still get denied — for example, when a service needed prior authorization that was never obtained. That is why FPRR is the more honest measure of how well the whole revenue cycle is working, and why it pairs naturally with the other numbers on your monthly dashboard alongside your medical billing operation’s collection metrics.
What drags first-pass resolution rates down?
- Eligibility and registration errors — wrong payer, inactive coverage, demographic typos.
- Missing prior authorizations — the service was performed before authorization was confirmed.
- Coding and modifier issues — mismatched diagnosis-to-procedure combinations or missing required modifiers, which is where an experienced medical coding review pays for itself.
- Payer-specific rules — each payer’s edits differ, and a claim that sails through one payer can bounce at another.
- Untracked payer policy changes — policies update throughout the year, and yesterday’s billable combination can be today’s denial.
How do you improve FPRR?
Work the causes, not the symptoms: verify eligibility before every visit, confirm authorizations before service, scrub claims against payer-specific edits before submission, and review your top denial reasons monthly so the same error never causes a third denial. Practices that lack the staff time to do this consistently are exactly who benefits from outsourcing — a dedicated billing team lives in these edits all day. Physician-founded in 1992, AMS Solutions has spent more than 30 years building that first-pass discipline for practices in all 50 states.
Frequently Asked Questions
Is first-pass resolution rate the same as first-pass acceptance rate?
No. Acceptance rate usually measures claims accepted by the clearinghouse or payer front door, not paid. A claim can be accepted and still denied. Resolution means the claim was actually adjudicated and paid on the first try.
How often should we measure FPRR?
Monthly is the practical cadence for most practices. Measure it alongside your denial reasons so you can see not just the score but what is moving it.
Does a high FPRR guarantee healthy collections?
Not by itself. You can resolve claims on the first pass but still undercharge, miss charges entirely, or write off balances too easily. FPRR is one gauge on the dashboard, not the whole dashboard.
What should we do first if our FPRR is low?
Pull your last 90 days of denials and rejections and group them by reason. In most practices a small number of causes drives the majority of rework, so fixing the top two or three moves the rate quickly.
