About Dr. Carlson

Practice. Dr. Erik Carlson is a board-certified orthopedic surgeon practicing in Middlebury, Connecticut. The latest annual CMS data records 26 knee replacements. That is #35 in Connecticut for knee replacement. A Medicare provider since 2008.

Estimated 2024 total: 90 – 110 procedures (all insurers)
Medicare fee-for-service share of national volume in 2024: 23% to 28% for knee 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 23% to 28% for knee 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.
