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

Why is the Medicaid comparison limited to Delaware 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. Delaware (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 billing footprint is concentrated: lifetime Medicare revenue is $666.7K while there is no Medicaid billing on file, so the practice effectively operates on a single-payer (Medicare) footprint for the data available. The lack of Medicaid activity suggests limited participation in state Medicaid networks or a patient panel that is predominantly Medicare-eligible.

Revenue is highly concentrated in a small set of procedural retinal codes: the top three Medicare codes (J0178, 67028, J2777) account for 74.8% of this provider’s total Medicare revenue. Those three codes include J0178 at $350.5K, 67028 at $79.6K, and J2777 at $67.9K, indicating dependence on a few high-volume treatment codes for the majority of revenue.

The code mix indicates a retina-focused, procedure-driven ophthalmology practice: J0178 (aflibercept injection), J2777 (faricimab injection), J9035 (bevacizumab injection), and 67028 (intravitreal injection procedure) together dominate billing, supported by high-volume retinal imaging with 92134. This pattern (large share from injection drugs plus OCT imaging) is consistent with an office-based intravitreal injection suite treating retinal disease rather than a general primary eye-care clinic.

J0178 is the single largest Medicare revenue driver at $350.5K (52.7% of total Medicare revenue) but the provider ranks #1908 of 3204 nationally for this code (40th percentile), a placement the source labels as "typical, unremarkable volume for this code." In other words, while J0178 dominates this provider’s revenue mix, the provider is not a top national volumetric performer for aflibercept relative to peers.

Retinal imaging (92134) is a notable strength: 1.5K claims produced $44.1K (6.6% of Medicare revenue) and the provider ranks #1555 of 26868 nationally (94th percentile), described as "notably above typical national volume for this code." High OCT volume relative to peers suggests the practice does substantial diagnostic imaging to support injection-based management.

There is a contrast across injection drug codes: J2777 shows 2.3K claims and $67.9K revenue but ranks #1926 of 2039 (5th percentile) and is labeled "typical, unremarkable volume for this code," while J9035 accounts for $34.7K and ranks in the 91th percentile (#175 of 1852) and is also described as "typical, unremarkable volume." These divergent percentiles imply the provider’s relative position varies by drug product—high claim counts for some agents do not always translate to above‑peer ranking, reflecting differences in national utilization patterns or pricing.

Office/clinic evaluation-and-management and comprehensive exam codes make up a smaller portion of revenue compared with injections and imaging: 92014 produced $58.7K (8.8% of Medicare revenue) and common E/M codes such as 99214 contributed $11.2K (1.7%). This distribution underscores that procedural and drug administration services are the primary revenue drivers rather than routine E/M visits.

The provider has long tenure on file, with an NPI enumerated 2006-07-28 (~20 years ago), which indicates a sustained market presence. That longevity combined with a concentrated retina-centric revenue mix suggests an established, procedure-oriented ophthalmology practice rather than a newly entering competitor.
