123 Medicare services, 2024 (ranked within specialty)

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)
Hospital Discharge Day Management, More Than 30 Minutes99239	42	$99
Initial Hospital Care With Moderate Level of Medical Decision Making, If Using Time, at Least 75 Minutes99223	29	$149
Emergency Department Visit With Moderate Level of Medical Decision Making99284	28	$102
Emergency Department Visit With Low Level of Medical Decision Making99283	12	$60
Prolonged Hospital Inpatient Or Observation Care Evaluation and Management Service(s) Beyond the Total Time for the Primary Service (when the Primary Service Has Been Selected Using Time on the Date of the Primary Service); Each Additional 15 Minutes By ThG0316	12	$26

Typical Medicare-allowed amounts for these services range $26–$149 (2024). The Medicare-allowed amount is what Medicare recognizes for a service under fee-for-service — a reference figure for 2024, 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 · 1 distinct drug on file.

Drug	Part D claims (2024)	Beneficiaries
Oxycodone Hcl	11	11

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.
