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

Why is the Medicaid comparison limited to Iowa 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. Iowa (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

Medicare dominates this provider’s public payer footprint: lifetime Medicare revenue is $1.6M while there is no Medicaid billing on file, making the practice effectively single‑payer (Medicare) in the available claims data and likely dependent on Medicare reimbursements for the bulk of analyzed activity. This concentration will be relevant for network negotiations or risk-based arrangements that rely on a broader payer mix.

Revenue is highly concentrated in a small set of biologic injection codes: the top three Medicare codes by revenue account for 65.5% of total Medicare revenue, led by J2777 which alone represents $765.6K (46.6% of Medicare revenue). This indicates a strong reliance on intravitreal biologic therapy as the primary revenue engine rather than routine office visits or ancillary testing.

Clinical/service-line implication: the code mix is characteristic of a retina-focused ophthalmology practice that performs high volumes of intravitreal injections (J2777, J0178, J2778, J0179) alongside cataract procedures (66984, 66982) and diagnostic imaging (92134, 92136, 92133). The prominence of J2777 and other anti-VEGF/biologic injection codes suggests the provider’s operations are built around in-office procedural throughput and drug administration.

Competitive standing for the dominant injection code is middling nationally: J2777 activity ranks #357 of 2039 providers nationally (82th percentile) and is labeled as "typical, unremarkable volume for this code," meaning the provider is an active but not exceptional national performer for faricimab administration. Other high-revenue procedure codes show similar patterns of solid but not market-leading volume: J0178 ranks #2464 of 3204 (23th percentile; typical, unremarkable volume) and J2778 ranks #525 of 1208 (57th percentile; typical, unremarkable volume).

Certain procedural and evaluation codes show above-average placement relative to peers: cataract extraction with lens insertion 66984 ranks #3803 of 15965 (76th percentile; typical, unremarkable volume) and posterior-segment imaging 92134 ranks #2070 of 26868 (92th percentile; typical, unremarkable volume), indicating the provider performs cataract surgery and retinal imaging at or above many peers. These percentile positions point to a practice that mixes retail procedural volume with diagnostic imaging at a meaningful scale.

Statistical outlier signal in new-patient office visits: 99204 is reported at $16.2K and ranks #11192 of 227068 (95th percentile; notably above typical national volume), which suggests unusually high relative activity for moderate-complexity new patient visits compared with national peers. This may reflect a steady inflow of new referrals or an intake pattern that drives above-average billing for new, moderately complex evaluations.

Practice tenure is long-standing: the provider’s NPI enumerated on 2006-05-19 (~20 years ago), indicating roughly two decades of enrollment in federal payor systems. That longevity supports the interpretation that the observed billing mix reflects an established practice pattern rather than a short-term or emerging specialty shift.

Operational and payer considerations: absence of Medicaid billing (no Medicaid billing on file) combined with heavy reliance on high-cost biologic injections (e.g., J2777 at $765.6K) may shape contracting priorities—payors and health systems should view this provider primarily as a Medicare-facing retina/cataract procedural provider when evaluating referral networks, utilization management, or specialty carve-outs. The mix of high-volume injection codes and above-typical new-patient visits suggests the practice is oriented toward procedural throughput supported by a stable referral base.
