    Key Findings

    Clinical/service mix centers on intravitreal biologic therapy and ophthalmic diagnostics: the top revenue codes are J0178 (aflibercept), Q5128 (ranibizumab biosimilar), and J3590 (unclassified biologics), supported by procedure codes for intravitreal injection (67028) and retinal imaging (92134). This mix indicates a practice focused on medical retina care—regular anti-VEGF injections plus diagnostic imaging and follow-up exams—rather than primarily surgical ophthalmology.

    Medicare revenue is highly concentrated in a few drug codes: the precomputed top three Medicare codes account for 58.9% of this provider's total Medicare revenue, with J0178 generating $634.1K (32.0%), Q5128 $269.1K (13.6%), and J3590 $265K (13.4%) of the $2M lifetime Medicare revenue. That concentration means movement in pricing, utilization, or payer coverage for these biologics would materially affect the provider’s Medicare receipts.

    This provider is effectively single‑payer at the state level: lifetime Medicare revenue is $2M while there is no Medicaid billing on file. Absence of Medicaid activity suggests limited exposure to state program mix and potential reliance on Medicare commercial-like reimbursement dynamics.

    Competitive standing on major drug codes is mixed: J0178 ranks #1348 of 3204 (58th percentile) and J3590 ranks #255 of 631 (60th percentile), both described as "typical, unremarkable volume," whereas Q5128 ranks #116 of 373 (69th percentile), indicating relatively stronger adoption or higher volume of the ranibizumab biosimilar versus national peers. Overall the provider is a modest-to-strong regional participant for certain anti‑VEGF agents rather than a national dominant provider.

    Two service codes are statistical outliers upward: 92014 (comprehensive established patient exam) produced $164.5K (8.3%) and ranks in the 98th percentile (labeled an "extreme outlier"), and 92134 (retinal imaging/OCT) produced $57.1K (2.9%) and ranks in the 95th percentile ("notably above typical"). These elevated volumes suggest a high throughput of established medical retina patients and significant reliance on advanced retinal imaging as part of ongoing disease management.

    Operational profile shows variation between high claim counts and low average payments for some items: for example J2777 appears in 5.3K claims but with a low $29 avg paid/claim and $153.1K revenue (7.7%), while several high‑revenue biologics have much higher avg paid/claim (e.g., J3590 at $2172 avg). This pattern implies a mix of high‑frequency, low‑unit‑value services alongside lower-frequency, high‑unit‑value drug reimbursements shaping the revenue stream.

    Tenure and likely established referral base: the NPI was enumerated on 2013-05-07 (~13 years ago), indicating more than a decade of billing history. Combined with the heavy established‑patient exam volume and elevated imaging use, the data are consistent with a mature practice that has an entrenched outpatient retina/ophthalmology service line.

    Revenue risk concentration is present: with $2M in Medicare revenue and no Medicaid billing, and 58.9% of Medicare revenue coming from the top three drug codes, the provider’s financial performance appears sensitive to changes in anti‑VEGF utilization, biosimilar uptake, or Medicare drug payment policies. Non‑drug services (E/M and imaging) provide complementary revenue but do not offset the concentration in biologic reimbursements.
