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 Moderate Level of Decision Making, If Using Time, 30 Minutes Or More99214 | 59 | $103 |
| Established Patient Office Or Other Outpatient Visit With Low Level OD Decision Making, If Using Time, 20 Minutes Or More99213 | 57 | $72 |
| Injection of Drug Or Substance Under Skin Or Into Muscle96372 | 16 | $11 |
| Detection Test By Immunoassay With Direct Visual Observation for Streptococcus, Group a (strep)87880 | 15 | $16 |
| Detection Test By Multiplex Amplified Probe Technique for Severe Acute Respiratory Syndrome Coronavirus 2 (sars-Cov-2) (covid-19) and Influenza Virus Types a and B87636 | 13 | $140 |
Typical Medicare-allowed amounts for these services range $11–$140 (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 · 4 distinct drugs on file.
| Drug | Part D claims (2024) | Beneficiaries |
|---|---|---|
| Zolpidem Tartrate | 20 | 12 |
| Azithromycin | 12 | 11 |
| Doxycycline Hyclate | 12 | 12 |
| Rosuvastatin Calcium | 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.
