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

Why is the Medicaid comparison limited to California 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. California (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 NPI is a retina-focused ophthalmology practice with procedure-driven revenue dominated by intravitreal biologic injections: J0178 ($1.6M, 25.3% of Medicare revenue), Q5128 ($1.5M, 24.3%), and J2777 ($1M, 16.4%). The code mix—large volumes of anti-VEGF and related intravitreal drug codes alongside retina imaging codes—is consistent with a practice organized around frequent injection visits and retinal disease management.

Revenue concentration is high: the precomputed top 3 codes account for 65.9% of this provider's total Medicare revenue, underscoring dependence on a small set of high-revenue drug and injection services for the $6.4M in reported Medicare revenue. Such concentration magnifies financial sensitivity to changes in reimbursement, drug utilization, or clinical guidelines for those specific therapies.

Payer mix is effectively single-payer Medicare: lifetime Medicare revenue is $6.4M and there is no Medicaid billing on file. Analysts should treat this provider as Medicare-dependent for public payer activity, with no Medicaid footprint to evaluate for in‑state competitive comparisons.

Competitive standing varies by service: the provider is an extreme outlier on Q5128 (rank #5 of 373, 99th percentile) and shows unusually high national volume for retina imaging and injection administration—92134 (rank #56 of 26868, 100th percentile) and 67028 (rank #54 of 4255, 99th percentile) are also extreme outlier positions. By contrast, J0178 (rank #384 of 3204, 88th percentile) and J2777 (rank #201 of 2039, 90th percentile) are high-volume but characterized in the dataset as more typical, indicating dominance in select product lines rather than uniformly across all retinal drugs.

J3490 (unclassified drugs) is a notable revenue driver with 366 claims and $446.5K in revenue (7.0% of Medicare revenue) and a high average paid/claim ($1220), suggesting use of non-standard or high-cost drug entries alongside labeled biologics. Because J3490 is an unclassified code, the underlying products and clinical reasons are not explicit in the claims data and should be investigated if drug-level detail matters for contracting or utilization management.

Operational footprint emphasizes procedure throughput over general office E/M: injection administration code 67028 has 3.4K claims ($401.8K, 6.3%) and retina imaging codes 92134 (4.8K claims, $154.6K) and 92250 (720 claims, $20.2K) indicate heavy use of diagnostic imaging to support frequent injection visits. By comparison, established-patient comprehensive visits (92014, $183.5K, 2.9%) and E/M codes (for example, 99214, $3.5K, 0.1%) make up a much smaller share of billed Medicare revenue.

The practice shows a sustained presence in Medicare billing: NPI was enumerated 2006-06-13 (~20 years ago), which, together with $6.4M in lifetime Medicare revenue, points to a long-established retinal specialty practice with a consistent procedural orientation. This tenure supports interpretation of current high volumes as baked into the provider’s established workflow rather than a transient spike.

Drug mix includes multiple branded and biosimilar ranibizumab and related agents across the top codes—Q5128 ($1.5M), Q5124 ($315.9K, 5.0%), and J2778 ($416.9K, 6.5%)—indicating active use of biosimilars alongside other anti-VEGF agents. Given the prominence of these specific drug codes and their differing competitive rank signals (Q5128 an extreme outlier vs. others characterized as typical), payers should consider product-level contracting and utilization trends when assessing cost exposure and supplier negotiations.
