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 South Dakota for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to South Dakota 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. South Dakota (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

This provider’s Medicare revenue is concentrated in intravitreal anti-VEGF drug treatments: J0178 (aflibercept) generated $331K (53.3% of Medicare revenue), J2777 (faricimab) generated $146.2K (23.5%), and J2778 (ranibizumab) generated $40.1K (6.5%). The precomputed top-three share is 83.2% of total Medicare revenue, indicating the practice is heavily dependent on injectable retinal pharmacotherapy as its primary revenue driver.

Operationally, the CPT/HCPCS mix (large volumes of J0178, J2777 and the intravitreal procedure 67028 alongside retinal imaging 92134 and ophthalmology E/M codes 92012/92014) describes a retina-focused ophthalmology practice that performs frequent drug injections and ongoing monitoring rather than a broad multispecialty clinic. The presence of 882 claims for 92134 and substantial counts for established-patient exams supports a model of recurrent visits for chronic retinal disease management.

Although J0178 is the single largest revenue source at $331K and 486 claims, this provider’s national standing on that code is modest: J0178 ranks #1954 of 3204 providers (39th percentile) and is labeled in the dataset as “typical, unremarkable volume.” Similarly, J2777—despite showing 5K claims—has a lower per-claim payment ($29) and ranks #1525 of 2039 (25th percentile), also characterized as “typical, unremarkable volume,” so the practice is not a dominant national provider for these drug codes.

There is an interesting volume-to-revenue contrast in J2777: 5K claims produced $146.2K in revenue at an average paid/claim of $29, suggesting this code contributes materially by count but yields lower average reimbursement per claim compared with J0178 ($681 avg paid/claim). This pattern implies a workflow with many lower-paid administrations (J2777) together with fewer higher-paid administrations (J0178), which could reflect formulary/reimbursement differences between drug products.

Imaging and follow-up services appear comparatively strong: 92134 produced $22.1K (3.5% of Medicare revenue) across 882 claims and ranks #2364 of 26868 providers (91th percentile), even while the dataset labels it “typical, unremarkable volume.” High percentile placement for 92134, together with above-typical rankings for established patient exams (92012 at the 83th percentile and 92014 at the 68th percentile), reinforces that the practice carries significant diagnostic and chronic-care monitoring activity.

The broader code mix shows the practice conducts both procedure-focused visits and standard ophthalmology evaluations: 67028 appears with 407 claims and $34.2K (5.5% of Medicare revenue) and is ranked #2421 of 4255 providers (43th percentile), while E/M codes such as 92012 (349 claims, $19.9K) and 92014 (243 claims, $15.3K) contribute modestly to revenue. This balance indicates injections and drug administration are the primary revenue engine, with office evaluations and imaging supporting ongoing management.

Payer mix is effectively single-payer Medicare: lifetime Medicare revenue is $623.7K and there is no Medicaid billing on file (none below), so Medicaid does not meaningfully contribute to this provider’s recorded revenue or service mix. Analysts should treat this profile as Medicare-dominant when evaluating utilization, competitive position, and reimbursement sensitivity.

The provider’s NPI was enumerated on 2014-04-03 (~12 years ago), indicating an established billing history long enough to have developed stable patterns in retina-focused revenue generation. Taken together, the data portray a long-tenured ophthalmology physician with a concentrated, retina-centered practice that is a modest national participant for its highest-revenue drug codes but shows relatively strong utilization of diagnostic imaging and follow-up services.
