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

Why is the Medicaid comparison limited to Maine 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. Maine (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.

This provider bills almost exclusively to Medicare with total Medicare revenue of $374.6K and Medicaid revenue listed as none (no Medicaid billing on file), making the practice effectively single‑payer from the public-payor perspective. That concentration means analyses of patient mix and utilization should focus on Medicare patterns rather than dual‑payer dynamics.

Revenue is highly concentrated in a small set of ophthalmology procedures: the precomputed top‑3 Medicare codes account for 68.8% of the provider's Medicare revenue, led by 66984 which alone represents $160.7K (42.9% of Medicare revenue). The other two leading codes are 92014 ($62.2K, 16.6%) and 66821 ($34.5K, 9.2%), confirming most Medicare dollars derive from a compact set of services.

The code mix points to a cataract‑focused surgical practice supported by office‑based ophthalmology services: 66984 (cataract extraction with intraocular lens insertion), 66821 (YAG laser capsulotomy), and 92136 (IOL biometry) together signal a workflow centered on cataract surgery, preoperative planning and common postoperative laser management. Additional codes such as 92134 and 92133 for retinal and optic nerve imaging further indicate routine diagnostic follow‑up and monitoring integral to that surgical pathway.

Competitive standing versus national peers is mixed by code: 66984 ranks #1766 of 15965 providers nationally (89th percentile; typical, unremarkable volume), and 92014 ranks #2602 of 35415 (93th percentile; typical, unremarkable volume), indicating solid but not dominant national volumes for core cataract and comprehensive exam services. By contrast, 66821 ranks #447 of 10087 (96th percentile; typical, unremarkable volume described as notably above typical national volume), suggesting this provider performs posterior capsulotomy at a comparatively higher rate than most peers.

One notable statistical outlier in the billing mix is 99204, which is labeled an extreme outlier and ranks in the 99th percentile nationally; the provider reported 305 claims for 99204 at $99 avg paid/claim totaling $30.2K (8.1% of Medicare revenue). This unusually high national ranking for moderate‑complexity new patient E/M visits may reflect referral inflow, a high proportion of new patient consultations, or local practice patterns emphasizing thorough initial evaluations.

The practice also bills meaningful amounts for diagnostic and ancillary services that support surgical care: 92136 shows 525 claims at $27 avg paid/claim for $14.2K (3.8% of Medicare revenue), 92134 shows 380 claims for $9.9K (2.6%), and 92133 shows 210 claims for $5K (1.3%). These diagnostic imaging volumes are consistent with preoperative measurements and postoperative retinal/optic nerve monitoring typical of an ophthalmic surgery practice.

The provider has an established NPI tenure, enumerated on 2006-02-27 (~20 years ago), which, together with the concentrated Medicare revenue and the code mix dominated by cataract surgery and related diagnostics, suggests a stable, locally entrenched ophthalmology practice focused on surgical cataract care and follow‑up services.
