Gross Collection Rate (GCR)
Gross Collection Rate (GCR) is total payments received divided by total charges billed, expressed as a percentage. It measures how much of what you billed you actually collected, before adjustments and write-offs.
Definition.
Gross Collection Rate is a private-practice construct. It assumes that what you charge bears a defensible relationship to what you expect to be paid. In fee-for-service environments, that holds: a physician group charges 250 percent of Medicare, collects 38 percent of charges from a commercial payer that pays at 110 percent of Medicare, and the math reconciles cleanly. GCR fails badly in PPS environments (FQHCs, RHCs) where the payment basis is per-encounter not per-charge.
Key points.
How GCR is calculated
Total payments / Total charges. Both measured over the same time period (typically a month, quarter, or year). Adjustments and contractual write-offs are not subtracted from charges; that is what makes GCR different from Net Collection Rate (NCR).
When GCR is useful
Fee-for-service physician practices where the charge-to-payment relationship is consistent across payers. Variance in GCR over time signals payer mix shifts, contract changes, denial pattern changes, or write-off rate changes.
When GCR fails
FQHC, RHC, and other PPS-paid providers. PPS payment is per-encounter and unrelated to charges. A blended GCR at an FQHC averages four streams (Medicaid PPS, FFS Commercial, FFS Medicare, Self-Pay) that behave completely differently. The number is essentially noise.
Healthy GCR ranges
Vary widely by specialty and payer mix. Primary care: 35-45%. Surgical specialties: 28-40%. Outpatient mental health: 38-55%. ABA: 40-65% depending on payer mix. There is no universal benchmark.
