Total number of knee replacements this clinician billed to Medicare in the most recent 12-month claims period, as reported by CMS.
CMS reports this as a range rather than an exact number because it suppresses counts of 10 and below. It does not mean zero.
CMS suppresses counts of 10 or fewer to protect patient privacy, so it publishes the range rather than a number and no exact percentile exists. Every clinician in that range sits below those with a count of 11 or more, which places them at or below the 32nd percentile. This is not a count of zero, and it is not a measure of the clinician's total practice.

Dr. Wilson's Knee Replacement Billing Volume Compared to Peers
CMS reports this clinician's count as a range rather than an exact number, so no single point can be marked. Every clinician CMS reports as 1-10 sits below every clinician with an exact count above that range, which puts them at or below the 32nd percentile: the shaded band. The curve begins at the 32nd percentile because CMS suppresses counts below 11, and 3,333 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. Wilson
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 |
|---|---|---|
| Hip replacement | 1-10 | 46% or below |
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 knee 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 knee replacement, partial knee replacement, and revision of a previous knee replacement to calculate the total number of knee replacements. Billing variation and coding errors could potentially affect CMS's data. Therefore, the knee replacement volume data reported by CMS may be higher or lower than the actual total knee replacements performed by a clinician. We share the total knee 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 knee replacement and reported one of those specialties?
