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

Why is the Medicaid comparison limited to Michigan 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. Michigan (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 is effectively a Medicare-only billing entity: Total Medicare revenue: $2.8M and Total Medicaid revenue: none (no Medicaid billing on file). The absence of any Medicaid claims on file means payer mix is concentrated entirely in Medicare, so commercial or state-level Medicaid exposures are not visible in this dataset.

Revenue is highly concentrated in a small set of injectable biologics: the precomputed top 3 Medicare codes by revenue account for 84.5% of this provider's total Medicare revenue, driven by J0178 ($1.6M, 56.8%), J2778 ($448.4K, 16.2%), and J2777 ($316.7K, 11.4%). This concentration indicates the practice’s financial performance is reliant on intravitreal biologic therapy reimbursements.

The code mix and code descriptions point to a medically focused retina practice that centers on intravitreal injection therapy and supporting diagnostics. High-revenue injectable codes (J0178, J2778, J2777) alongside retinal imaging codes such as 92134 and 92250 and E/M codes like 99213/99214 suggest routine injection visits with frequent imaging and office follow-up rather than primarily surgical retina care.

Competitive standing for the top anti-VEGF/biologic codes is above-average but not dominant nationally: J0178 ranks #401 of 3204 providers nationally (87th percentile; typical, unremarkable volume for this code) and J2778 ranks #158 of 1208 providers nationally (87th percentile; typical, unremarkable volume for this code). These ranks indicate the provider manages materially higher-than-average volumes of aflibercept and ranibizumab relative to peers, but sits within the common practice distribution for injectable therapies.

Certain service lines show notably high relative activity versus national peers—office E/M and fundus photography stand out. 99213 is flagged as an extreme outlier (rank #1397 of 457151 providers nationally; 100th percentile; extreme outlier, far above typical national volume for this code) and 92250 is also an extreme outlier (rank #453 of 25087 providers nationally; 98th percentile; extreme outlier, far above typical national volume for this code), while 92134 is notably above typical (95th percentile). This pattern is consistent with a workflow that pairs frequent injection visits with retinal imaging and frequent E/M encounters for established patients.

Surgical vitreoretinal procedures appear limited in scale: 67042 reports 13 claims and $11.3K revenue and ranks #869 of 1087 providers nationally (13th percentile; typical, unremarkable volume for this code), indicating that pars plana vitrectomy and related surgical interventions are not a major revenue driver for this practice. The low surgical rank supports the interpretation that this is a predominantly medical retina/injection-focused operation rather than a surgery-heavy practice.

The provider has an extended tenure in the public enrollment files, which supports interpretation of established referral and operational patterns: NPI enumerated 2006-06-07 (~20 years ago). Long tenure combined with concentrated injection revenue and high E/M/imaging volumes suggests an established clinical workflow centered on chronic retina disease management.

Because a majority of revenue comes from a few high-cost biologic codes—with J0178 showing an average paid/claim of $688 and accounting for $1.6M of revenue—this practice’s financial profile is exposed to changes in biologic utilization, pricing, or payer formulary policies. Reliance on a narrow set of injectable agents creates business sensitivity to reimbursement or utilization shifts even though current volumes place the provider above average for those therapies.
