Verified Medicare Cases

Hip Replacement
99 verified cases
#5 in Colorado
Estimated 2024 total: 300 – 400 procedures (all insurers)
Medicare fee-for-service share of national volume in 2024: 25% to 33% for hip replacement
How is this estimated?

Medicare Part B fee-for-service claims are one payer stream among several, and the share they represent differs by procedure. In 2024 it was 25% to 33% for hip replacement. Each verified count above is divided by its own procedure's range, and the results are added, to estimate total practice volume across all payers. The verified Medicare count is the definitive, audited figure; this is a range derived from published national volume projections, not a measurement, and an individual practice can sit well outside it: how these ranges are derived, and their sources.
