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

Why is the Medicaid comparison limited to Iowa 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. Iowa (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 footprint is the dominant and effectively sole public-payer activity on file: total Medicare revenue is $3.4M while there is no Medicaid billing on file, indicating a single-payer (Medicare-focused) revenue profile in the available data. Analysts should treat this profile as Medicare-driven rather than balanced across Medicare and Medicaid.

Revenue is highly concentrated in three injectable biologic codes: J2777 (31.7%), J0178 (30.2%), and J2778 (23.9%). Those top 3 Medicare codes together account for 85.8% of the provider’s total Medicare revenue, signaling that intravitreal biologic therapy is the core service line driving financial performance.

The mix of top codes and their descriptions (J2777, J0178, J2778 and the procedure 67028) points to a retina-focused ophthalmology practice primarily delivering intravitreal injections of anti-VEGF and related biologics. This code mix is consistent with a practice model built around recurring, drug-based ophthalmic treatment rather than predominantly office-based primary eye care.

Competitive standing for the three leading drug codes is mixed but skewed toward meaningful national presence: J2778 ranks #56 of 1208 providers nationally (95th percentile; typical, unremarkable volume for this code) showing particularly strong relative activity with ranibizumab, J2777 ranks #184 of 2039 (91th percentile; typical, unremarkable volume for this code), and J0178 ranks #821 of 3204 (74th percentile; typical, unremarkable volume for this code). These ranks indicate the provider is a notable national participant for some biologics (especially ranibizumab) while being a solid but not dominant player across the broader anti-VEGF/biologic market.

Several procedure and imaging codes are extreme or notable outliers versus national peers: 92134 is in the 99th percentile and identified as an "extreme outlier, far above typical national volume for this code," and 67028 is in the 97th percentile and labeled "notably above typical national volume for this code." High volumes of retinal imaging and standalone intravitreal procedures reinforce the interpretation of a high-throughput retina treatment practice.

Use of unclassified biologics (J3590) is relatively large for this provider (952 claims, $93.3K revenue) and ranks #16 of 631 providers nationally (98th percentile; notably above typical national volume). That elevated percentile for an unclassified biologic code suggests occasional billing for non-standard or newly introduced injectable products alongside the named anti-VEGF agents.

Office-based evaluation and management activity supports substantial established-patient follow-up: 99213 has 534 claims and ranks #24056 of 457151 providers nationally (95th percentile; notably above typical national volume for this code). While E/M codes contribute a small share of total revenue relative to biologics, these high follow-up volumes are consistent with recurring treatment regimens requiring frequent visits.

Provider tenure is long-standing: the NPI was enumerated on 2005-08-17 (~21 years ago). This extended period of Medicare enrollment supports the observed sustained Medicare revenue and established pattern of retina-focused procedural and drug revenue.
