    Key Findings

    This provider’s Medicare business is highly specialized around intravitreal injection therapeutics: J0178 (aflibercept), J2777 (faricimab-svoa), and J2778 (ranibizumab) are the top revenue-generating codes and together account for 78.0% of total Medicare revenue, indicating a practice focused on retinal medical therapy rather than broad general ophthalmology services. The presence of frequent imaging codes such as 92134 (retinal imaging, posterior segment) further supports a retina-focused workflow where diagnostic imaging and repeated injections are central to day-to-day operations.

    Revenue concentration on Medicare is pronounced — total Medicare revenue is $1.4M and the precomputed top-3 share is 78.0% — meaning most of the practice’s Medicare billing depends on a narrow set of high-cost intraocular injection codes. This concentration implies financial sensitivity to changes in utilization patterns, reimbursement, or drug choice for those few J-codes.

    Payer mix is effectively single-payer from the available data: the provider reports $1.4M in Medicare revenue and has no Medicaid billing on file, so Medicaid contributes nothing to the current billing profile. For payers and network planners, this means contracting and care-management discussions should prioritize Medicare population dynamics and drug utilization rather than Medicaid populations.

    Competitive standing on key drugs varies by molecule. The provider’s J0178 activity (aflibercept) generated $805K and ranks in the 65th percentile nationally, a typical but solid volume for this drug. In contrast, J2777 (faricimab-svoa) shows high claim count but ranks in the 19th percentile nationally despite contributing $123.5K, suggesting above-average use relative to smaller national providers in absolute claims but lower revenue per claim and modest national standing by revenue.

    Some procedural services show strong relative intensity: 92134 (retinal imaging) produced $63.5K and ranks in the 96th percentile nationally, labeled here as notably above typical national volume. That high percentile for imaging indicates the practice performs diagnostic imaging at a much higher rate than most peers, consistent with a retina-focused clinic that monitors chronic retinal disease closely.

    Other commonly billed ophthalmology E/M and exam codes (92014, 92012, 99213) appear at typical to above-typical percentiles without dominating revenue — 92014 generated $48.1K (84th percentile) and 92012 $17K (75th percentile) — implying the practice manages ongoing medical follow-up visits for established patients but derives the majority of revenue from injections rather than comprehensive new-patient encounters.

    The provider’s Medicare utilization includes some therapies with relatively high national rank for bevacizumab (J9035) where $42.7K in revenue places the practice in the 94th percentile, indicating strong use of bevacizumab compared with peers. This suggests a mixed drug strategy that includes both originator biologics and lower-cost alternatives, which may reflect clinical practice patterns or payer mix for specific patients.

    Tenure is long: the NPI was enumerated around 2006-07-04 (~20 years ago), indicating the provider has an established billing history and likely stable referral relationships. For network planners and competitors, this longevity aligns with a mature outpatient retinal practice rather than a newer entrant.

    Overall, the profile depicts a mature, Medicare-focused ophthalmology practice concentrated on intravitreal injections and retinal imaging, with a narrow revenue base (78.0% from the top three injection codes) and mixed national competitiveness across individual drugs — some codes show notably above-typical imaging volume while others are typical or modest in national ranking.
