Total number of hip 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 46th percentile. This is not a count of zero, and it is not a measure of the clinician's total practice.

Dr. Hirsch's Hip 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 46th percentile: the shaded band. 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.

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?
