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

Why is the Medicaid comparison limited to Massachusetts 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. Massachusetts (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.

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider’s reported payer mix is effectively single-payer Medicare: total Medicare revenue is $1.9M and there is no Medicaid billing on file. The absence of Medicaid activity means analyses of Medicaid exposure, state-level contract participation, or dual-eligible care patterns cannot be supported from these records.

Revenue is highly concentrated in a small set of drugs and procedures: the precomputed top 3 Medicare codes account for 83.2% of this provider's total Medicare revenue. In particular J0178 accounts for $1.2M revenue (65.9% of this provider's total Medicare revenue), with 67028 contributing $169.4K (9.0%) and J2777 contributing $158.3K (8.4%).

The code mix and top revenue drivers identify a retina-focused ophthalmology practice that centers on intravitreal anti-VEGF therapy: J0178 (aflibercept), J2777 (faricimab), and J9035 (bevacizumab) dominate the revenue profile and 67028 documents intravitreal injection as a frequent procedure. Complementary diagnostic imaging codes such as 92134 and 92250 appear in the top codes, consistent with routine retinal imaging and monitoring workflows that support injection clinics.

Despite J0178 representing the majority of revenue, the provider’s national competitive standing for that code is modest: J0178 ranks #633 of 3204 providers nationally (80th percentile; labeled "typical, unremarkable volume"). Similarly, J2777 ranks #1464 of 2039 (28th percentile; "typical, unremarkable volume"). These rankings indicate the practice is a solid contributor in anti-VEGF delivery but not a dominant national outlier on volume for its primary drug.

Several office visit and imaging codes are comparatively high versus peers, signaling above-typical clinic throughput: 99213 ranks #17400 of 457151 providers (96th percentile; "notably above typical national volume"), 99204 ranks #7289 of 227068 providers (97th percentile; "notably above typical national volume"), and 92250 ranks #1008 of 25087 providers (96th percentile; "notably above typical national volume"). This pattern suggests the practice maintains relatively high new- and established-patient visit volumes and frequent retinal imaging in support of its injection services.

Surgical and other procedure revenue is small relative to injection therapy: codes such as 67036 ($11.5K) and 67108 ($11.3K) appear in the list but account for only a fractional share of Medicare revenue. The presence of these lower-volume surgical codes indicates the provider performs some posterior-segment procedures, but these are not major revenue drivers compared with intravitreal drug therapy.

The provider’s tenure is long enough to indicate established practice operations: NPI enumerated 2006-05-31 (~20 years ago). This longevity, combined with concentrated revenue from recurring injection therapies, is consistent with a stable, outpatient retina practice model focused on sustained follow-up and treatment regimens.

From a business-risk perspective, the practice’s heavy dependence on a single high-revenue drug (J0178 at $1.2M and 65.9% of Medicare revenue) creates revenue concentration exposure to changes in drug reimbursement, utilization guidelines, or patient mix. While the practice shows strong visit and imaging volumes that support the injection clinic, payers should note that most Medicare dollars are tied to a narrow set of injectable therapies (top 3 = 83.2%).
