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 | 74 | $120 |

| Imaging of Optic Nerve92133 | 25 | $33 |
| Exam of Visual Field With Extended Testing92083 | 15 | $59 |
| Imaging of Retina92134 | 12 | $38 |
Typical Medicare-allowed amounts for these services range $33–$120 (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 |
|---|---|---|
| Latanoprost | 64 | 21 |
| Prednisolone Acetate | 23 | — |
| Brinzolamide/Brimonidine Tartbrand: Simbrinza | 22 | — |
| Cyclosporinebrand: Restasis | 17 | — |
| Perfluorohexyloctane/Pfbrand: Miebo | 15 | — |
| Timolol Maleate | 14 | — |
| Brimonidine Tartrate | 11 | — |
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.
