About Dr. Aggrey
Practice. Dr. Gerald Aggrey is a board-certified orthopedic surgeon practicing in Eugene, Oregon. The latest annual CMS data records 17 knee replacements and 11 hip replacements, 28 procedures in all. That is #66 in Oregon for knee replacement. A Medicare provider since 2015.
Trend. Medicare records run from 2020 to 2024, 5 years. Volume peaked at 47 in 2021 and stands at 28 now. Reporting changes and payer mix can both move that number.
National context. Among 6,612 knee replacement surgeons tracked nationally, 17 procedures is below the national average of 45. Medicare covers part of all joint replacements, so true volume is likely higher.
Local context. Eugene has 10 orthopedic surgeons in the current Medicare data. Comparing volume and procedure mix across them is one way to narrow a shortlist.

Verified Medicare Cases
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 23% to 28% for knee replacement, 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.
