A good first-pass denial rate for an independent medical practice is under 5 percent. The industry median sits between 5 and 10 percent. Anything above 10 percent is a systemic front-end problem, not a payer problem. That said, denial rate alone is the wrong metric to optimize. What actually predicts revenue performance is worked-denial rate, appeal success rate, clean claim rate, and A/R aged over 90 days. All four together.
This page pulls the current industry benchmarks from MGMA and HFMA, explains why denial rate in isolation misleads practice owners, and defines the four metrics that actually measure denial management performance. Every calculation is spelled out so a practice can measure itself in an afternoon.
Key takeaways
- Best-in-class first-pass denial rate: under 5 percent (MGMA, HFMA).
- Industry median: 5 to 10 percent.
- The typical billing team works only 40 percent of denials. High performers work over 85 percent.
- Denial rate is a leading indicator. What you actually recover is what pays the practice.
- Four metrics matter more than denial rate on its own: worked-denial rate, appeal success rate, A/R aged over 90 days, clean claim rate.
Industry benchmarks
The two most-cited sources for revenue cycle benchmarks in independent practices are MGMA (Medical Group Management Association) and HFMA (Healthcare Financial Management Association). Both publish annual data drawn from thousands of practices.
| Segment | Best-in-class | Median | Struggling |
|---|---|---|---|
| First-pass denial rate | Under 5% | 5 to 10% | Over 10% |
| Clean claim rate | Over 95% | 90 to 95% | Under 90% |
| Worked-denial rate | Over 85% | 40 to 60% | Under 40% |
| A/R aged over 90 days | Under 15% | 15 to 25% | Over 25% |

Why denial rate alone is misleading
Practices ask "what is our denial rate?" like it is a scoreboard. It is not. It is a leading indicator that measures the health of the front end (eligibility, coding, prior authorization). What actually pays the practice is what gets recovered on the back end.
Consider two practices:
- Practice A: 6% first-pass denial rate. Works 30% of denials. Loses 70% of denied revenue to write-off.
- Practice B: 11% first-pass denial rate. Works 90% of appealable denials. Wins 55% of appeals.
Practice B has almost double the denials but collects far more revenue. Denial rate is one variable. Recovery is the outcome. Any practice measuring itself only on denial rate is optimizing the wrong number.
"I have seen practices with a 12 percent denial rate outperform practices with a 6 percent denial rate on cash collected per provider. The difference was one team worked their denials and the other team did not. The number on the dashboard is not the number that pays the mortgage."

The 4 metrics that matter more
1. Worked-denial rate
Definition: Of the claims denied on first pass, what percent did the billing team correct, resubmit, or appeal within 30 days?
Formula: (Denials worked in the period) ÷ (Total denials received in the period) × 100.
Why it matters: Industry data consistently shows the typical billing team works only 40 percent of denials, meaning 60 percent are silently written off. Every unworked denial is money the practice earned and gave away. High-performing teams work over 85 percent of appealable denials.
2. Appeal success rate
Definition: Of the denials appealed at first level, what percent were overturned in the practice's favor?
Formula: (Appeals overturned in the period) ÷ (Appeals filed in the period) × 100. Segment by denial type.
Why it matters: Appeal success rates should be tracked by denial type, because averages hide problems. Timely filing appeals typically win 25 to 40 percent of the time. Medical necessity appeals win 40 to 60 percent when clinical documentation is solid. Bundling and modifier appeals win 50 to 70 percent when the coding argument is properly built.
3. A/R aged over 90 days
Definition: What percent of total accounts receivable is aged more than 90 days from date of service?
Formula: (A/R over 90 days) ÷ (Total A/R) × 100.
Why it matters: A/R over 90 days is where money goes to die. Claims aged more than 90 days recover at less than half the rate of claims worked inside 30 days. Best-in-class practices keep this metric under 15 percent. Anything over 25 percent means the denial workflow is broken, the appeal workflow is broken, or both.
4. Clean claim rate
Definition: Of all claims submitted, what percent are accepted by the payer on first submission with no rejection or denial?
Formula: (Claims paid on first submission) ÷ (Total claims submitted) × 100.
Why it matters: Clean claim rate is the inverse leading indicator to denial rate. If clean claim rate drops, front-end workflows (eligibility, coding, prior auth) are the problem, not the payer. Best-in-class is above 95 percent.
What "good" looks like by practice size
Benchmarks shift with practice size and specialty mix. A 15-provider multi-specialty practice with dedicated denial specialists should hit tighter numbers than a 3-provider primary care practice with a shared biller. From consulting engagements across 1 to 15 provider practices, here is what "good" typically looks like:
| Practice profile | Denial rate | Worked-denial rate | A/R over 90 days |
|---|---|---|---|
| 1 to 3 providers, primary care | Under 7% | Over 70% | Under 18% |
| 4 to 8 providers, primary care | Under 6% | Over 80% | Under 15% |
| 4 to 8 providers, specialty (ortho, ophth, GI) | Under 8% | Over 80% | Under 18% |
| 9 to 15 providers, multi-specialty | Under 5% | Over 85% | Under 15% |
Specialty practices carry naturally higher denial rates because they touch more prior authorization workflows, more modifier disputes, and more medical necessity criteria. A 7 percent denial rate at an orthopedic practice with strong appeal recovery is healthier than a 4 percent denial rate at a primary care practice that writes off every appealable denial.
How to measure it in your practice
Pull the following from the practice management system for the last 90 days:
- Total claim lines submitted.
- Total claim lines denied on first pass.
- Total denials worked (corrected, resubmitted, or appealed) within 30 days of receipt.
- Total appeals filed, segmented by denial type.
- Total appeals overturned, segmented by denial type.
- Aging report snapshot: A/R by bucket (0 to 30, 31 to 60, 61 to 90, over 90).
Calculate the four metrics using the formulas above. If any one metric is below the benchmark for your practice profile, that is the workflow that needs attention first. The Revenue Health Assessment walks through this exact diagnostic in about 12 minutes.

What is a good denial rate for a medical practice?
MGMA benchmarks put the target initial denial rate at under 5 percent for high-performing practices, with the industry median hovering between 5 and 10 percent. Anything above 10 percent signals a systemic problem in front-end workflows (eligibility, coding, prior authorization) rather than a payer problem. HFMA cites a similar 4 to 5 percent target as best-in-class.
How do I calculate my denial rate?
Denial rate equals total claim lines denied on first pass divided by total claim lines submitted in the same period, expressed as a percentage. Track it monthly by payer. If a payer's denial rate is more than double your practice average, the problem is with that payer's edits or your submission workflow for that payer, not your overall billing operation.
What is a worked-denial rate?
The worked-denial rate measures what percent of denials the billing team actually touches, corrects, or appeals inside a set window. Industry data shows the typical billing team works only 40 percent of denials, meaning 60 percent are written off silently. High-performing teams work over 85 percent of appealable denials within 30 days.
What denial rate should a 5-provider primary care practice target?
A well-run 5-provider primary care practice should target a first-pass denial rate under 6 percent, a worked-denial rate over 85 percent, a clean claim rate over 92 percent, and A/R aged over 90 days under 15 percent of total A/R. Hitting three of the four consistently is where practices start seeing meaningful cash acceleration.
How often should we review denial metrics?
Monthly at minimum, weekly for practices in a recovery push. Denial rate by payer is the most useful weekly cut because payer edits shift constantly. A/R aging is a monthly review. Appeal success rate by denial type is a quarterly review because appeal outcomes lag by 60 to 90 days.
