Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Idaho for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Idaho only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Idaho (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

Clinical/service mix centers on medical retina and cataract surgery: the provider’s largest single-line revenue driver is J0178 ($317.9K, 51.9% of Medicare revenue), an aflibercept injection code used in intravitreal anti‑VEGF therapy, and the second-largest is 66984 ($88.6K, 14.5%), a standard cataract surgery code. Together with 92014 ($47.9K, 7.8%), these codes suggest a practice that combines a high-volume intravitreal injection program with surgical cataract services and routine comprehensive ophthalmic exams.

High revenue concentration in a small set of services: the precomputed top-3 codes account for 74.2% of this provider’s total Medicare revenue, indicating that a narrow mix of treatment modalities—anti‑VEGF injections, cataract extraction with IOL, and comprehensive exams—dominates billing. This concentration means changes in utilization or reimbursement for those few codes would materially affect the provider’s Medicare revenue.

Effectively single-payer footprint: lifetime Medicare revenue is $611.7K while there is no Medicaid billing on file, so the provider’s reported public-payer activity is almost entirely Medicare. Analysts should treat this profile as a Medicare-dependent billing footprint rather than a balanced Medicare/Medicaid mix.

Competitive standing is mixed across major codes: J0178 ranks #2002 of 3204 nationally (37th percentile) and is characterized as typical, unremarkable volume for the code despite being the provider’s largest revenue source, while 66984 ranks #4686 of 15965 (71st percentile) indicating above-typical surgical volume. The comprehensive established exam 92014 ranks #4011 of 35415 (89th percentile), showing relatively high exam volume compared with national peers.

Diagnostics and imaging support an active injection/surgical practice: 92134 (computerized retinal imaging) shows 639 claims and $17.9K revenue (2.9% of Medicare revenue) and ranks in the 89th percentile, and related imaging codes 92133 and 92136 also register meaningful volume. This pattern—high OCT/retinal imaging usage alongside intravitreal injections—aligns with a practice model that manages retinal disease with ongoing imaging-guided therapy.

Evidence of an integrated surgical pathway: cataract-related follow-up and supporting services appear in the mix, with 66821 (YAG capsulotomy) at $17K (2.8% of Medicare revenue) and 92136 (IOL measurements) generating $7.2K (1.2% of Medicare revenue). Those codes, together with 66984, suggest the provider performs cataract surgery and the expected pre- and post-operative services rather than only office-based care.

Revenue profile shows dependence on J0178 injections: a single HCPCS (J0178) accounts for $317.9K and 51.9% of Medicare revenue, underscoring that intravitreal pharmacologic therapy is the dominant income stream. For contracting or utilization reviews, injections and associated imaging should be prioritized given their outsized share of the revenue mix.

Established billing tenure with moderate lifetime Medicare volume: the provider’s NPI was enumerated 2009-04-10 (~17 years ago), indicating long-standing enrollment, and lifetime Medicare receipts total $611.7K, which positions this clinician as a steady but modest Medicare biller over that period. The combination of long tenure and concentrated service lines provides a stable historical record for peer comparisons and trend analysis.
