What this provider does (Medicare)

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

Initial Hospital Care With Moderate Level of Medical Decision Making, If Using Time, at Least 75 Minutes99223	16	$166

Established Patient Office Or Other Outpatient Visit With Moderate Level of Decision Making, If Using Time, 30 Minutes Or More99214	15	$107

Typical Medicare-allowed amounts for these services range $76–$166 (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 · 7 distinct drugs on file.

Drug	Part D claims (2024)	Beneficiaries
Omeprazole	47	17
Sucralfate	35	14
Ondansetronbrand: Ondansetron Odt	32	21
Pantoprazole Sodium	24	—
Oxycodone Hcl	24	24
Famotidine	23	—
Misoprostol	13	—

These counts cover prescriptions paid through Medicare Part D in 2024 — they 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 , 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.
