Vendors love to talk about their process. Numbers, by contrast, are hard to fake. Insist on these eight KPIs, and you will separate operational billing partners from marketing shops in the first hour of any evaluation.
The 8 KPIs
1. Net collection ratio (NCR)
What it measures: Actual payments received / (charges minus contractual adjustments).
Target: 96%+ is healthy. 93-95% is acceptable but slipping. Below 93% means money is being left on the table through timely-filing lapses, missed appeals, or write-offs that should have been recovered.
Why it matters most: NCR is the hardest number to manipulate. A vendor can tell a good story about first-pass acceptance while quietly writing off appealed claims — NCR catches that.
2. Days in accounts receivable (A/R)
What it measures: Total A/R balance / average daily charges.
Benchmark: MGMA median 47 days, better performers 36 days. Industry-wide, 2026 saw the median trend up 2.4 days driven by Medicare Advantage prior-authorization backlogs.
Red flag: Above 55 days is a warning; above 65 days suggests systemic follow-up failure.
3. First-pass acceptance rate
What it measures: Percentage of claims accepted by payer on first submission without edits or rejection.
Benchmark: HFMA target 95-98% for top-quartile practices. Industry benchmark of 90%+ is the commonly cited floor.
Why it matters: Every rejected claim costs $25-$118 to rework depending on complexity. Practices at 80% first-pass are paying for 2x the rework of practices at 95%.
4. Denial rate
What it measures: Percentage of claims denied on first submission.
Benchmark: Top-quartile below 5%, industry average 9-12%, over 50% of US healthcare organizations now report denial rates above 10% per MGMA 2024 data.
Red flag: Above 12% denial rate, or a denial rate trending up quarter over quarter without explanation.
5. Denial-recovery rate
What it measures: Percentage of denied claims successfully appealed and collected.
Benchmark: Industry median 40-50%. Top performers hit 65%+.
Why it matters: A high denial rate is survivable if the recovery rate is high. A low denial rate looks great in isolation but hides money left on the table if recovery is low.
6. Clean-claim rate
What it measures: Percentage of claims submitted without any error, rejection, or need for correction before payer adjudication.
Benchmark: HFMA target 95-98%. Industry acceptable floor 94%.
How it differs from first-pass acceptance: Clean-claim is about pre-submission quality; first-pass is about post-submission adjudication. They should track close together but a 5%+ gap suggests payer-specific rule gaps.
7. Aged A/R over 90 days
What it measures: Percentage of total A/R that has been outstanding over 90 days.
Benchmark: Healthy is under 15% of total A/R. 15-25% signals follow-up capacity issues. Over 25% is a five-alarm fire.
Why it matters: Money not collected within 90 days is exponentially less likely to be collected at all. Aged A/R is where vendor complacency shows up first.
8. Charge-lag time
What it measures: Business days from patient encounter to claim submission.
Benchmark: Under 2 business days is excellent. 2-4 days is acceptable. Over 5 days materially hurts cash flow and increases timely-filing risk.
Why it matters: Cash-flow leading indicator. Long charge-lag foreshadows aging A/R and increased denials.

What to do with the numbers
Put the eight KPIs on a single dashboard. Review monthly with the vendor account manager and quarterly with the vendor operations lead. Any KPI trending in the wrong direction two months in a row is grounds for a written action plan from the vendor, and any KPI two consecutive quarters below benchmark is grounds for contract renegotiation or termination for cause.
Vendors who resist any of the eight are telling you where the problems are.
