Medicare volume is ranked against active providers in the same specialty. Signals a provider has no public data for (e.g. Medicare claims) are left out of the score entirely — never counted as zero — so providers without that data are not penalized.

What this provider does (Medicare)

Based on Medicare fee-for-service claims, 2024; not all care is captured.

Service (HCPCS)	Medicare services	Typical Medicare-allowed (2024)
Established Patient Office Or Other Outpatient Visit With High Level of Medical Decision Making, If Using Time, 40 Minutes Or More99215	23	$164
Established Patient Office Or Other Outpatient Visit With High Level of Medical Decision Making, If Using Time, 40 Minutes Or More99215	22	$191
Prolonged Office Or Other Outpatient Evaluation and Management Service(s) Beyond the Maximum Required Time of the Primary Procedure Which Has Been Selected Using Total Time on the Date of the Primary Service; Each Additional 15 Minutes By the Physician OrG2212	17	$36
New Patient Office Or Other Outpatient Visit With a High Level of Medical Decision Making, If Using Time, 60 Minutes Or More99205	15	$217

Typical Medicare-allowed amounts for these services range $36–$217 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, not a price quote and not what you would be billed. Medicare Part B covers roughly an eighth of all NPIs (65+ skew); services with fewer than 11 beneficiaries are suppressed by CMS.

What this provider prescribes (Medicare Part D)

Top drugs by Medicare Part D claim volume, 2024 · 2 distinct drugs on file.

Drug	Part D claims (2024)	Beneficiaries
Carbidopa/Levodopabrand: Carbidopa-Levodopa	64	35
Carbidopa/Levodopabrand: Carbidopa-Levodopa Er	21	12

Medicare Part D only. These counts cover prescriptions paid through Medicare Part D in 2024 — they do notinclude cash-pay, commercial-insurance, Medicaid, or Part B–administered drugs, and badly undercount high cash-pay categories (e.g. GLP-1 weight-loss, testosterone, and ED medications). Any drug with 10 or fewer claims is omitted by CMS, and beneficiary counts under 11 are suppressed — so a missing drug means no Part D record, never zero. This is a factual claims summary, not an endorsement, not medical advice, and not a consumer report. Source: CMS Medicare Part D Prescribers — by Provider and Drug.
