What is fee-for-service?

Under fee-for-service (FFS), a provider submits a claim listing each service delivered, and the payer pays a set or negotiated amount for each one. A primary care visit, a lab panel and an X-ray on the same day generate three separate payments.

FFS is the historical default in U.S. health care. Original Medicare, many state Medicaid programs and most commercial insurance contracts still pay providers this way, even when a value-based arrangement is layered on top.

In Medicare usage, "fee-for-service" also names a program: Original Medicare Parts A and B, as distinct from Medicare Advantage, where private plans receive capitated payments.

How fee-for-service payment works

Prices come from a fee schedule such as the Medicare Physician Fee Schedule, from a prospective payment system that groups related services into one rate, or from a negotiated commercial contract. A typical payment follows these steps:

• The provider documents the encounter and codes it with procedure codes (CPT or HCPCS) and diagnosis codes (ICD-10-CM).
• The provider submits a claim to the payer, usually electronically.
• The payer checks eligibility, coverage and coding edits during claims adjudication.
• The payer pays the allowed amount for each approved line, minus patient cost sharing such as deductibles and coinsurance.

Why fee-for-service matters

Because FFS pays more for more services, critics argue it rewards volume over outcomes. That concern drove the shift toward value-based care, accountable care organizations and bundled payments. Most of those models still run on FFS claims underneath and settle shared savings or losses after the fact.

For analysts, FFS is what makes claims data rich. Every paid service leaves a coded record with a provider NPI, a date and an amount, which is why Medicare FFS utilization files can show procedure volumes by physician and facility. Services paid under capitation often leave thinner encounter records, so FFS data can understate activity in markets with heavy Medicare Advantage or managed care enrollment.
