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 Low Level OD Decision Making, If Using Time, 20 Minutes Or More99213 | 61 | $92 |
| New Patient Office Or Other Outpatient Visit With Straightforward Medical Decision Making, If Using Time, 15 Minutes Or More99202 | 41 | $75 |
| 2019-Ncov Coronavirus, Sars-Cov-2/2019-Ncov (covid-19), Any Technique, Multiple Types Or Subtypes (includes All Targets), Non-CdcU0002 | 11 | $50 |
Typical Medicare-allowed amounts for these services range $50–$92 (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 · 7 distinct drugs on file.
| Drug | Part D claims (2024) | Beneficiaries |
|---|---|---|
| Albuterol Sulfatebrand: Albuterol Sulfate Hfa | 21 | 20 |
| Cephalexin | 21 | 21 |
| Prednisone | 19 | 19 |
| Methylprednisolone | 12 | 12 |
| Azithromycin | 12 | 12 |
| Doxycycline Hyclate | 12 | 12 |
| Mupirocin | 11 | 11 |
Medicare Part D only. 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.
