Total number of hip replacements this clinician billed to Medicare in the most recent 12-month claims period, as reported by CMS.
Percentile rank of 15 hip replacements compared to peers CMS lists under Orthopedic Surgery, Sports Medicine, or Hand Surgery who have billed at least one hip replacement to Medicare in the same period.

Dr. Whitney's Hip Replacement Billing Volume Compared to Peers
Reading the curve: find a volume along the bottom, and the line gives the percentile of the clinicians CMS lists under Orthopedic Surgery, Sports Medicine, or Hand Surgery at or below it. The marked point is this clinician. The curve begins at the 46th percentile because CMS suppresses counts below 11, and 4,504 clinicians in the group carry that range instead of a number. It ends at the 99th percentile, and a small number of clinicians bill more than that.

Other procedures CMS reports for Dr. Whitney
CMS publishes a separate count for this clinician in the categories below. Each figure is counted and ranked entirely on its own, so the counts are not added together and the percentile ranks are not comparable with one another.
| Procedure | Procedures billed | Percentile rank |
|---|---|---|
| Knee replacement | 27 | 56% |
Each percentile rank compares this clinician only with others CMS lists in that same category, so the comparison group changes from row to row. A count shown as a range means CMS suppressed it to protect patient privacy; it does not mean zero.
Understanding CMS Data
These figures are based on hip replacements billed to Original Medicare and Medicare Advantage as reported by the Centers for Medicare & Medicaid Services (CMS) in their June 2026 data release. The CMS data doesn't include procedures performed for patients who have other health care coverage (e.g., commercially insured, self pay, or VA). Furthermore, CMS sums up specific billing codes that cover first-time hip replacement, partial hip replacement, and revision of a previous hip replacement to calculate the total number of hip replacements. It does not include every operation in which a hip prosthesis is implanted: replacements performed to treat a broken hip are counted under a billing code CMS leaves out of this category. Billing variation and coding errors could potentially affect CMS's data. Therefore, the hip replacement volume data reported by CMS may be higher or lower than the actual total hip replacements performed by a clinician. We share the total hip replacement figures for the clinicians CMS lists under Orthopedic Surgery, Sports Medicine, or Hand Surgery as CMS publishes them, without alteration.
National Percentile Calculation
CMS publishes its own percentile for this data using a single, national pool that also includes the clinicians listed with the specialties of Physician Assistant and Nurse Practitioner. We use CMS's percentile formula, but restrict the comparison group to the clinicians CMS records under Orthopedic Surgery, Sports Medicine, or Hand Surgery, so our number answers a narrower question: how does this clinician's procedure volume compare with other clinicians who billed Medicare for at least one hip replacement and reported one of those specialties?
