About Dr. Gualtieri
Practice. Dr. Anthony Gualtieri is a board-certified orthopedic surgeon practicing in Houston, Texas. The latest annual CMS data records 27 knee replacements and 19 hip replacements, 46 procedures in all. That is #271 in Texas for knee replacement. A Medicare provider since 2016.

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.
