    Key Findings

    This clinician’s billed activity is concentrated in Medicare with Total Medicare revenue: $919.8K and no Medicaid billing on file, so the provider functions effectively as a single-payer (Medicare) biller for the datasets shown. The absence of any Medicaid claims suggests a limited footprint in state-subsidized care or a panel skewed away from Medicaid-covered patients.

    Revenue concentration is extreme: the precomputed top 3 Medicare codes by revenue account for 81.0% of this provider's total Medicare revenue. Those top three are J0178 ($580.7K, 63.1%), 99214 ($83.4K, 9.1%), and 67028 ($81.5K, 8.9%), indicating most dollars flow from a small set of services.

    The code mix points to a retina-focused ophthalmology practice that combines high-volume intravitreal drug therapy with diagnostic imaging and office-based follow-up. J0178 (aflibercept) is the dominant revenue driver ($580.7K) and J9035 (bevacizumab, $34.4K) plus 67028 (intravitreal injection, $81.5K) and 92134 (retinal imaging, $34.2K) together indicate routine, repeated intravitreal injection workflows and OCT-based monitoring typical of medical retina management.

    Clinical-surgical capability appears present alongside injection services: procedural retina codes such as 67041 ($39.1K) and 67042 ($16.3K) and repair code 67108 ($24.3K) are billed, showing the provider performs vitreoretinal surgery in addition to injections and imaging. Notably, 67041 ranks #33 of 461 (93th percentile; typical, unremarkable volume), which signals meaningful surgical retina activity relative to peers.

    Office evaluation-and-management activity is also significant: 99214 generated $83.4K across 897 claims and ranks #14957 of 479517 (97th percentile; notably above typical national volume). This indicates a higher-than-typical level of moderate-complexity follow-up visits, consistent with ongoing management of chronic retinal disease requiring frequent assessment.

    Competitive standing by code is mixed. For the largest revenue driver, J0178 ranks #1449 of 3204 (55th percentile; typical, unremarkable volume), so while aflibercept dominates this practice’s revenue mix, the provider is not an outsized national volume leader for that drug. Conversely, other retinal services (for example, J9035 ranks #188 of 1852, 90th percentile; typical, unremarkable volume, and 92134 ranks #1971 of 26868, 93th percentile; typical, unremarkable volume) place the provider above many peers on imaging and some drug/service lines.

    The provider’s dependence on a single high-revenue drug is a notable business risk and operational driver: J0178 alone accounts for 63.1% of Medicare revenue ($580.7K). Such concentration means payment policy changes, drug utilization shifts, or site-of-service reimbursement updates affecting aflibercept could materially affect the practice’s Medicare revenue.

    The NPI tenure (NPI enumerated: 2007-06-12 (~19 years ago)) indicates a long-established billing history, which may explain sustained volumes across injections, imaging, E/M visits, and occasional vitreoretinal surgery. This longevity supports an interpretation of stable, specialty-focused operations rather than a recent ramp-up or transient practice pattern.
