About Dr. Ong

Practice. Dr. Bernard Ong is a board-certified orthopedic surgeon practicing in Las Vegas, Nevada. The latest annual CMS data records 32 knee replacements. That is #20 in Nevada for knee replacement. A Medicare provider since 2005.

Trend. Medicare records run from 2013 to 2024, 12 years. Volume peaked at 71 in 2019 and stands at 32 now. Reporting changes and payer mix can both move that number.

National context. Among 6,612 knee replacement surgeons tracked nationally, 32 procedures is below the national average of 45. Medicare covers part of all joint replacements, so true volume is likely higher.

Local context. Las Vegas has 26 orthopedic surgeons in the current Medicare data. Comparing volume and procedure mix across them is one way to narrow a shortlist.

Verified Medicare Cases

Knee Replacement
32 verified cases

Estimated 2024 total: 110 – 140 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.
