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
Amoxicillin	57	44
Clindamycin Hcl	13	12

Medicare Part D only. These counts cover prescriptions paid through Medicare Part D in 2024 — they do not include 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.
