| Metric | Formula | What it actually measures |
|---|---|---|
| Gross collection rate | Payments ÷ Charges × 100 | Mostly your fee schedule |
| Net collection rate | Payments ÷ (Charges − contractual adjustments) × 100 | Your actual collection performance |
This is the part that causes the most confusion, so it is worth being blunt about it. Gross collection rate is driven almost entirely by how you set your fee schedule. A practice that bills at 300% of Medicare will show a far lower GCR than an identical practice billing at 150% — while collecting exactly the same money from exactly the same payers.
Take a simple example. You bill $500,000. Your contracts mean $330,000 of that was never collectible — it is the negotiated discount you agreed to when you signed. You collect $150,000 of the remaining $170,000. Your gross collection rate is 30%, which looks alarming. Your net collection rate is 88%, which is the number that tells you something real: roughly $20,000 you were entitled to collect did not arrive.
So GCR is not useless — it is just a trend metric for your own practice, not a benchmark against anyone else. If your GCR drops while your fee schedule has not changed, something genuine has shifted. Comparing your GCR to another practice's tells you almost nothing except that you price differently.
There is no single healthy figure, because gross collection rate is governed almost entirely by how aggressively a practice sets its charge master. A practice billing at 200 percent of the Medicare fee schedule will post a gross collection rate near 45 percent; one billing at 130 percent will post nearer 70 percent. Neither practice is collecting better than the other. The only thing that separates them is the denominator they chose.
That is why comparing your gross collection rate against another practice, or against a published industry average, tells you almost nothing useful. The comparison that does work is against your own prior periods with the same fee schedule. Held steady, a falling gross collection rate is a genuine signal: payer mix is shifting, a contract has been renegotiated downward, or collections are slipping. Move the charge master and the metric resets, which is precisely why it should never be the number you manage the practice by.
Net collection rate carries no such flaw. Because it measures collections against what you were contractually entitled to collect, it is directly comparable between practices, between specialties and against the 95 percent benchmark. Use gross collection rate to sanity-check your pricing, and net collection rate to judge your billing.
