What this provider does (Medicare)

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

Initial Hospital Care With Straightforward Or Low Level of Medical Decision Making, Per Day, If Using Time, at Least 40 Minutes99221	12	$84

Typical Medicare-allowed amounts for these services range $80–$132 (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 · 3 distinct drugs on file.

Drug	Part D claims (2024)	Beneficiaries
Omeprazole	36	16
Linaclotidebrand: Linzess	13	—
Sodium Chloride/Nahco3/Kcl/Pegbrand: Peg 3350-Electrolyte	13	13

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.

Open Payments discloses payments and transfers of value (meals, travel, consulting, research, royalties) from drug and device makers to providers. This is a transparency signal, not a verdict — such payments are legal and common, and their presence is neither an endorsement nor a criticism. Source: CMS Open Payments, program year 2024.
