    Key Findings

    This provider is effectively single‑payer in the claims on file: total Medicare revenue is $2.4M while there is no Medicaid billing on file (none below), so operational scale and payer exposure are concentrated in Medicare rather than a dual Medicaid/Medicare mix. That concentration means reimbursement and volume trends in Medicare will largely determine revenue risk and growth for this provider.

    Revenue is highly concentrated in intravitreal injection products: the precomputed top three Medicare codes account for 87.3% of the provider's Medicare revenue, with J2777 alone representing $1M (42.2% of Medicare revenue), J0178 contributing $743.6K (30.4%), and J2778 contributing $356.5K (14.6%). This concentration indicates the practice derives the vast majority of its Medicare dollars from pharmacologic retinal therapy rather than from office visits or minor procedures.

    The code mix and descriptions point to a retina‑focused ophthalmology practice that primarily delivers intravitreal anti‑VEGF/faricimab therapy and associated diagnostics: high volumes for J2777 (faricimab), J0178 (aflibercept), and J2778 (ranibizumab) are complemented by retinal imaging codes such as 92134 and angiography codes like 92235/92242, supporting an interventional retina service line rather than a general comprehensive ophthalmology model. The routine use of 67028 (isolated intravitreal injection) at $131.4K (5.4%) further confirms a procedurally oriented practice pattern.

    Competitive standing on the top revenue codes is mixed: for J2777 the provider ranks #208 of 2039 (90th percentile), placing them in the upper decile nationally for billed volume on that product, while the dataset labels the activity as "typical, unremarkable volume for this code." J0178 ranks #1208 of 3204 (62th percentile) and J2778 ranks #217 of 1208 (82th percentile); these ranks indicate the provider is a substantial, above‑average participant for some anti‑VEGF agents while mid‑pack for others.

    Retinal imaging appears to be an operational strength: 92134 shows 2K claims and $62.6K in revenue (2.6% of Medicare revenue) and ranks #1077 of 26868 (96th percentile), which the data labels as "notably above typical national volume for this code." High relative volume for 92134 suggests in‑house OCT capacity and frequent imaging follow‑up consistent with active intravitreal treatment protocols.

    Office evaluation & management services generate only modest Medicare revenue relative to injections: 99204 ($12.6K, 0.5%), 99214 ($9.6K, 0.4%), and 99213 ($8.2K, 0.3%) are all small contributors. This reinforces that the practice’s business model is procedure‑driven (drug and imaging revenue) rather than visit‑driven, with limited incremental income coming from E/M encounters.

    Surgical retina activity is present but limited in scale: vitrectomy and related procedure codes such as 67028 ($131.4K, 5.4%), 67041 ($16K, 0.7%), 67042 ($13.5K, 0.6%), and 67036 ($9.4K, 0.4%) show occasional operative work. These low counts and revenue shares indicate the provider performs some retinal surgery but that operating room procedures are a small part of overall Medicare income compared with injection therapy.

    Provider tenure is long: the NPI was enumerated on 2007-06-14 (~19 years ago), implying an established practice likely supported by an enduring referral base and clinical relationships, which plausibly underpins the sustained, high injection and imaging volumes reported in Medicare.
