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

Why is the Medicaid comparison limited to Nevada 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. Nevada (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

Practice mix and service lines center on retina-focused medical ophthalmology: the top revenue drivers are injectable retinal therapies J0178, J2777, and J2778 (J0178: 626 claims, $428.8K revenue, 28.7% of Medicare revenue; J2777: 13.3K claims, $386.3K revenue, 25.9%; J2778: 783 claims, $139.4K revenue, 9.3%), supported by a high volume of intravitreal procedures (67028: 739 claims, $62.1K) and extensive posterior-segment imaging (92134, 92133). This mix indicates an office-based model that combines frequent in-office injections with diagnostic imaging and follow-up E/M visits typical of a retina practice rather than a surgery-only ophthalmology service.

Revenue concentration is heavily weighted to three biologic injection codes: the precomputed top 3 Medicare codes account for 63.9% of this provider's total Medicare revenue. Given Total Medicare revenue: $1.5M, those three codes are the primary revenue engines and suggest financial exposure to changes in drug utilization, reimbursement, or formulary shifts affecting aflibercept, faricimab, and ranibizumab.

The provider is effectively single-payer in scale: Total Medicare revenue is $1.5M while there is no Medicaid billing on file. This absence of Medicaid activity indicates the practice’s revenue base and payer negotiations are driven entirely by Medicare beneficiaries and fee-for-service relationships tied to Medicare reimbursement.

Competitive standing for the top injectable drugs is modest rather than dominant: J0178 ranks #1738 of 3204 providers nationally (46th percentile; typical, unremarkable volume), J2777 ranks #779 of 2039 (62th percentile; typical, unremarkable volume), and J2778 ranks #522 of 1208 (57th percentile; typical, unremarkable volume). In other words, the practice bills materially for these drugs but does not appear as a national high-volume outlier among biologic injectors.

Contrast in service-level intensity: several E/M and imaging codes are far above peer norms, signaling high clinic throughput. For example, 99214 (1.1K claims, $89.9K revenue, 6.0%) is described as an extreme outlier (98th percentile), 99204 (388 claims, $42.3K, 2.8%) is an extreme outlier (100th percentile), 99212 (863 claims, $32.8K, 2.2%) is an extreme outlier (100th percentile), 92133 (614 claims, $14.1K, 0.9%) is an extreme outlier (99th percentile), and 92134 (1.6K claims, $43.1K, 2.9%) is notably above typical (95th percentile); collectively these entries point to unusually large volumes of office visits and diagnostic testing relative to national peers.

Surgical activity exists but is not the primary revenue driver: cataract extraction with IOL (66984: 341 claims, $138.8K, 9.3%) contributes meaningfully to Medicare revenue and ranks #3718 of 15965 (77th percentile; typical, unremarkable volume). Additional procedure codes such as 66821 (115 claims, $28.1K, 1.9%) also appear at typical national volumes, indicating the practice performs surgery but is not an outsized surgical center compared with national peers.

Tenure is long-standing and likely underpins the high E/M and imaging throughput: the NPI was enumerated on 2005-07-12 (~21 years ago), which is consistent with an established patient panel and durable referral relationships that can support recurrent injection schedules and frequent follow-up testing. This longevity, combined with the procedural mix, suggests a stable ophthalmology practice focused on chronic retinal disease management.
