Lifetime revenue by payer source (source: CMS Medicare & Medicaid claims data)
| Payer Source | Total Paid |
|---|---|
| Medicare | $323.4K |
| Medicaid | $110.7K |
This provider’s billing is materially larger to Medicare than to Medicaid, reporting Total Medicare revenue of $323.4K versus Total Medicaid revenue of $110.7K; Medicare represents the dominant payer by scale while Medicaid represents a meaningful secondary revenue stream. The NPI was enumerated 2007-12-17 (~19 years ago), indicating long-tenured activity in the market rather than a recent entrant.
The practice’s service mix is concentrated on higher-complexity office evaluation and glaucoma-focused diagnostics: Medicare top codes are 99215 (50.8% of Medicare revenue), 92083 (12.0%) and 92020 (9.6%), and these three codes together account for 72.4% of Medicare revenue. Code descriptions (high-complexity E/M, extended visual field testing, and gonioscopy) point to a workflow built around complex medical management and detailed glaucoma assessment rather than high volumes of intraoperative ophthalmic surgery.
Revenue concentration is high at both payers: the precomputed top-3 Medicare codes account for 72.4% of Total Medicare revenue, while the precomputed top-3 Medicaid codes account for 62.5% of Total Medicaid revenue. On the Medicaid side those top drivers are 92083 (23.4%), 92020 (21.3%), and 99215 (17.8%), indicating a similar diagnostic and E/M-heavy profile across payers rather than a payer-specific service mix.
This provider is a national high-volume outlier on multiple Medicare codes: 99215 ranks #150 of 145531 providers nationally (100th percentile; extreme outlier), 92083 ranks #266 of 25484 (99th percentile; extreme outlier), and 92020 ranks #24 of 7581 (100th percentile; extreme outlier). Those rank/percentile labels indicate a practice that bills far above typical national volumes for high-complexity office visits and glaucoma testing, consistent with a focused specialty practice serving a relatively large Medicare cohort.
State-level competitive standing in Medicaid is mixed: the provider ranks near the top in-state for 92020 (gonioscopy) at #2 of 17 providers (94th percentile), suggesting a leading position locally for glaucoma angle assessment, while 92083 (visual field) at #11 of 19 (44th percentile) and 99215 at #71 of 121 (42nd percentile) reflect more typical in-state volumes for extended visual field testing and high-complexity office E/M. The provider also shows strength in pre-op biometry for Medicaid, with 76519 ranked #2 of 6 in-state (80th percentile), indicating a notable role in cataract surgical planning within the state.
Procedure mix shows limited surgical cataract throughput relative to diagnostic care: Medicare lists 66984 (cataract extraction with IOL) at 32 claims and $14.8K revenue (4.6% of Medicare revenue), with a national rank of #12679 of 15965 (20th percentile; typical, unremarkable volume). Paired with modest counts for 66821 (YAG capsulotomy), these data point to a practice that performs some surgical procedures but is primarily oriented toward diagnostic evaluation and office-based management.
Imaging and diagnostic testing comprise a clear secondary revenue stream: Medicare line items such as 92250 (fundus photography, $20.9K, 6.5% of Medicare revenue; ranks #711 of 25087, 97th percentile; notably above typical) and 92134 (retinal imaging/OCT, $16.8K, 5.2% of Medicare revenue; 87th percentile; typical) plus Medicaid imaging revenue (92250 at $15.3K, 13.8% of Medicaid revenue) show sustained investment in retinal and anterior-segment diagnostic services. This mix supports management of retinal and glaucoma conditions and suggests in-office imaging contributes significantly to case management and documentation.
The practice shows utilization of non-face-to-face or extended E/M services with Medicare 99443 (93 claims, $10.1K, 3.1% of Medicare revenue; ranks #1478 of 14283, 89th percentile; typical), indicating some adoption of extended remote evaluation or telephone-based services alongside in-person care. Taken together with long tenure (NPI enumerated 2007-12-17 (~19 years ago)), the pattern suggests an established ophthalmology practice centered on complex office visits and glaucoma diagnostics with a secondary emphasis on imaging and selective surgical services.
