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.

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

Key Findings

This profile is effectively a single‑payer Medicare operation: lifetime Medicare revenue is $6.4M and there is no Medicaid billing on file, indicating the provider’s billed volume and revenue are concentrated in the Medicare program rather than split across Medicaid. The NPI was enumerated 2009-12-18 (~17 years ago), so the provider has an established billing history under this identifier.

Revenue concentration is high and dominated by intravitreal drug administration: the precomputed top‑3 Medicare codes account for 74.1% of total Medicare revenue, driven by J2777 ($2.8M, 43.3%), J0178 ($1.5M, 23.0%), and J3490 ($502.9K, 7.9%). This indicates the practice’s financial performance depends heavily on ophthalmologic drug injections and related drug billing.

The provider is a national outlier on one key pharmaceutical code: J2777 shows 95.3K claims and $2.8M revenue and ranks #22 of 2039 providers nationally (99th percentile; extreme outlier, far above typical national volume for this code), signaling unusually high faricimab administration relative to peers. This single code alone makes up the largest share of the provider’s Medicare revenue and drives much of its national prominence.

Complementary service lines reflect a high‑volume retinal practice: 92134 (4.1K claims, $140.8K) ranks #112 of 26868 providers nationally (100th percentile; extreme outlier), and 92012 (3.3K claims, $243.8K) ranks #10 of 17177 providers nationally (100th percentile; extreme outlier). These extreme outlier rankings for diagnostic imaging and intermediate established‑patient exams are consistent with a clinic that provides frequent follow‑up visits and retinal imaging for injection‑dependent conditions.

Competitive standing across several codes is mixed: beyond the extreme outlier status for J2777, some high‑revenue drug codes are more typical—J0178 ranks #491 of 3204 (85th percentile; typical, unremarkable volume) and J3490 ranks #180 of 2838 (94th percentile; typical, unremarkable volume)—indicating strong but not universally dominant placement across anti‑VEGF and unclassified drug billing. At the same time, other ophthalmology procedure codes (e.g., 67028 ranks #98 of 4255, 98th percentile; notably above typical) show elevated procedural throughput relative to peers.

Clinical mix suggests a retina‑focused ophthalmology practice: the predominance of intravitreal injection codes (J2777, J0178, J2778, J2781) together with high volumes of retinal imaging and follow‑up exam codes (92134, 92012, 92250) indicate routine, ongoing management of retinal disease with frequent injections and monitoring. The pattern—large drug revenue plus frequent diagnostic imaging—aligns with a service model centered on chronic retinal therapy administration.

Surgical volumes are present but limited compared with injection and imaging work: vitrectomy and related surgery codes such as 67036 ($37.2K, 50 claims, rank #83 of 832, 90th percentile) and 67042 ($30.5K, 32 claims, rank #239 of 1087, 77th percentile) account for small shares of revenue, suggesting the practice performs some posterior segment surgery but that injections and outpatient imaging are the core revenue drivers.

Concentration risk and operational implications: with 74.1% of Medicare revenue coming from the top three codes and $2.8M (43.3%) tied to a single drug code J2777, the provider’s financial performance and utilization profile are sensitive to shifts in drug utilization, formulary coverage, or reimbursement policy for intravitreal therapies. Analysts should treat this profile as highly dependent on outpatient injection volumes and associated follow‑up visits and imaging when modeling revenue and competitive behavior.
