How Much Does a Knee Replacement Cost? State by State

A complete state-by-state breakdown of knee replacement costs under Medicare.

Total knee replacement (HCPCS code 27447) is one of the most common major surgeries in America. The average Medicare-allowed cost is $1,374, but costs vary significantly by state.

With 20,971 providers performing this procedure, it's one of the most well-studied in Medicare data.

Why Costs Vary

Medicare adjusts payments based on geographic factors including local cost of living, labor costs, and practice expenses. States with higher costs of living — like California, New York, and New Jersey — tend to have higher allowed amounts.

What You Should Know

The "allowed" amount represents what Medicare considers reasonable for the procedure. Hospital charges can be 3-5x higher. If you're uninsured or out-of-network, asking for the Medicare rate as a starting point for negotiation is a common strategy.
