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

Why is the Medicaid comparison limited to Arizona 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. Arizona (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 totals $2.8M and there is no Medicaid billing on file, so the practice effectively operates as a single-payer (Medicare-focused) billing profile with no Medicaid contribution reported. Analysts should treat this entity as Medicare-dependent for public payer volumes and consider other commercial or self-pay channels outside this dataset.

Revenue is highly concentrated: the precomputed top 3 Medicare codes by revenue account for 83.3% of the provider’s total Medicare revenue. The dominance of a very small set of codes indicates a narrow procedure mix driving most Medicare receipts rather than a broadly diversified service portfolio.

Clinical mix and service line implications point to a retina/medical retina focus: J0178 (aflibercept) and J2777 (faricimab) together represent a majority of Medicare revenue (J0178 alone is $1.5M, 54.6% of Medicare revenue), indicating repeated intravitreal anti-VEGF injections as the core revenue stream, supported by related diagnostic imaging codes such as 92134. This pattern is consistent with an ophthalmology practice organized around pharmacologic retina therapy and imaging follow-up.

Competitive standing by code shows mixed placement: for the highest-revenue drug J0178 the provider ranks #432 of 3204 (87th percentile), and for J2777 ranks #454 of 2039 (78th percentile), signaling typical-to-strong participation nationally but not top-tier dominance in injection volumes. By contrast, some office visit and imaging codes are extreme outliers: 92012 ranks #106 of 17177 (99th percentile) and 92134 ranks #369 of 26868 (99th percentile), indicating unusually high volumes of intermediate eye exams and retinal imaging relative to peers. These outlier exam and imaging volumes suggest the practice manages a large follow-up/monitoring population.

Service intensity and procedure mix: high volumes of intermediate exams (92012) and retinal OCT imaging (92134) combined with very large counts of intravitreal injection claims (J0178: 2.2K claims, J2777: 22.4K claims) imply a workflow centered on frequent monitoring and repeat injections rather than high-volume surgical procedures. Surgical codes such as 67036 and 67028 appear but contribute much smaller shares of revenue, indicating surgery is a minor component of billed Medicare activity.

Tenure is long-standing: the provider’s NPI was enumerated around 2006-06-01 (~20 years ago), which supports interpretation of the high monitoring and injection volumes as the output of an established practice with mature referral and follow-up processes. Long tenure can correlate with stable patient panels and established treatment pathways for chronic retinal conditions.

Several codes show typical or unremarkable national volumes despite contributing meaningful revenue: for example J2778 (ranibizumab) ranks #753 of 1208 (38th percentile) and J7312 (dexamethasone implant) ranks #375 of 492 (22nd percentile). These placements indicate a reliance on certain branded biologics (aflibercept and faricimab) while other injectable therapies are used less frequently compared with national peers.

Given the lack of Medicaid claims, payer-mix implications include potential exposure to Medicare reimbursement trends for ophthalmologic pharmaceuticals and imaging. With no Medicaid billing on file, analysts should not rely on state Medicaid behavior to infer this provider’s low-income or dual-eligible patient activity, and should instead consider Medicare policy and commercial coverage for retina drugs when modeling revenue risk or utilization trends.
