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 | 26 | $136 |
| Established Patient Office Or Other Outpatient Visit With Moderate Level of Decision Making, If Using Time, 30 Minutes Or More99214 | 15 | $106 |
| Telephone Medical Discussion With Physician, 5-10 Minutes99441 | 11 | $38 |
Typical Medicare-allowed amounts for these services range $38–$136 (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 · 24 distinct drugs on file.
| Drug | Part D claims (2024) |
|---|---|
| Lamotrigine | 59 |
| Topiramate | 55 |
| Divalproex Sodium | 43 |
| Lacosamide | 42 |
| Clonazepam | 41 |
| Amitriptyline Hcl | 39 |
| Carbamazepinebrand: Carbamazepine Er | 35 |
| Levetiracetam | 34 |
| Divalproex Sodiumbrand: Divalproex Sodium Er | 32 |
| Clobazam | 31 |
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.
