Net Collection Rate
Net collection rate measures how much of the money a practice was entitled to collect it actually collected, after removing contractual adjustments. Formula: payments ÷ (charges − contractual adjustments). A healthy net collection rate is roughly 95% or higher; below 90% signals lost revenue from denials, write-offs, or weak follow-up.

What does net collection rate measure?
Net collection rate answers a blunt question: of the money you were actually entitled to collect, how much did you get? It strips out contractual adjustments — the difference between your charge and the contracted rate — so it is not distorted by how high you set your fees. What is left in the denominator is the money that was genuinely collectible. If you are leaving 5%+ on the table, this is the metric that shows it.
How do you calculate it?
The formula is payments ÷ (charges − contractual adjustments), measured over a trailing period long enough for claims to mature — 90 days is common, with some practices using a rolling 12 months.
Worked example: over the quarter, gross charges were $900,000. Contractual adjustments were $360,000, leaving $540,000 you were owed. You collected $513,000. Net collection rate = 513,000 ÷ 540,000 = 95%. The missing 5% — $27,000 — is your recoverable leakage, and it is what denial work and A/R follow-up are fighting for.
What counts as a good number?
Around 95% or higher is the healthy target; 97–99% is best-in-class. Below 90% means real dollars are being lost. Watch the trend as much as the level — a slide from 96% to 92% over two quarters is a process failure worth auditing, even though 92% still sounds respectable.
One caution before you trust any number: misclassifying recoverable balances as contractual adjustments makes net collection rate look artificially high because the denominator shrinks. If a biller codes a denied claim as a "contractual adjustment" instead of a write-off or a workable denial, the metric flatters you. Audit your adjustment codes before drawing conclusions.
How do you raise it?
- Work every denial. Unworked denials are the biggest single drag on NCR.
- Stop timely-filing write-offs. Claims written off past deadline are pure lost revenue.
- Pursue patient balances with consistent statements and up-front collections.
- Clean up posting. Correct adjustment coding keeps the denominator honest and keeps A/R days readable.
Frequently asked questions
Roughly 95% or higher is the widely cited healthy benchmark, meaning you collect at least 95 cents of every dollar you were contractually owed after adjustments. Best-in-class practices push toward 97–99%. Below 90% signals meaningful lost revenue — usually unworked denials, avoidable write-offs, or slow A/R follow-up rather than a pricing problem.
Gross collection rate divides payments by total charges and is heavily distorted by how you set your fee schedule. Net collection rate removes contractual adjustments first, so it measures collection performance against what you were actually owed. Net is the meaningful KPI; gross mostly reflects how far above contracted rates your charges sit.
The usual culprits are unworked denials, claims written off after timely-filing deadlines, patient balances that were never pursued, and posting errors that misclassify recoverable balances as adjustments. Split NCR by payer and by month to find the leak; a single slow payer or a broken denial queue often explains most of the gap.
