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

Why is the Medicaid comparison limited to Guam 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. Guam (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

ISLAND EYE CENTER is effectively a single‑payer provider in the available data: there is no Medicare billing on file while total reported Medicaid revenue is $157.5K. This payer concentration means Medicaid drives all observable public‑program reimbursements for the practice in our dataset.

Revenue is highly concentrated in routine ophthalmic evaluation codes: the precomputed top three Medicaid codes (92014, 92004, 92012) account for 98.4% of the provider's Medicaid revenue. Specifically, 92014 contributes 55.2%, 92004 contributes 29.0%, and 92012 contributes 14.2% of Medicaid revenue, showing heavy reliance on evaluation-and-management visits.

The code mix (92014, 92004, 92012) indicates the practice operates primarily as an outpatient ophthalmology clinic focused on comprehensive new‑patient and established‑patient eye examinations and follow‑up care. Procedural codes are present but minimal, so the operation appears to emphasize clinical exams and medical management rather than high volumes of procedures or surgical services.

Competitive standing across key Medicaid codes is modest rather than dominant. 92014 ranks #3 of 4 in-state (33th percentile; typical, unremarkable volume), 92004 ranks #2 of 4 (67th percentile; typical, unremarkable volume), and 92012 ranks #2 of 3 (50th percentile; typical, unremarkable volume), indicating routine participation relative to in‑state peers without outsized market share.

Top-code utilization and payment detail show visit‑level scale: 92014 has 976 claims with an average paid/claim of $89 for $86.9K in revenue, 92004 has 343 claims with an average paid/claim of $133 for $45.6K in revenue, and 92012 has 345 claims with an average paid/claim of $65 for $22.4K in revenue. These volumes confirm that calendar and clinical activity is concentrated in office evaluation visits rather than higher‑paid procedural encounters.

Procedural and diagnostic ancillary services exist but represent a very small share of Medicaid revenue: 67028 shows 38 claims, $54 avg paid/claim, $2.1K revenue (1.3% of Medicaid revenue) and 92134 shows 27 claims, $20 avg paid/claim, $540 revenue (0.3% of Medicaid revenue). This pattern suggests limited in‑office intravitreal injection and retinal imaging activity relative to exam visits.

The NPI was enumerated on 2007-03-26 (~19 years ago), indicating long tenure in the provider registry. Despite this longevity, the billing footprint in public programs is modest in scale and narrowly concentrated by service line.

From a risk/opportunity perspective, the absence of Medicare billing combined with heavy Medicaid dependence and concentration in evaluation codes leaves limited near‑term revenue diversification in the public payer mix. If expanding procedural services or capturing Medicare patients is a goal, the current data suggest those would be the areas to develop because they are not material in the reported Medicaid activity.
