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

Why is the Medicaid comparison limited to West Virginia 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. West Virginia (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’s service mix is focused on specialty ophthalmology with a strong combination of diagnostic electrophysiology, cataract surgery, and comprehensive office care. The top Medicare codes are 92273 (electrophysiologic retinal testing), 66984 (cataract extraction with IOL), and 92014 (comprehensive established eye exam), and the presence of high-volume imaging and biometry codes (92134, 92136, 76519) indicates an operation that performs both advanced diagnostic testing and supports surgical workflows. Such a mix is typical of a practice that handles pre‑op evaluation, intraoperative procedures, and post‑op management rather than only routine refractive or optometry visits.

Revenue is highly concentrated in a small set of services: the precomputed top three Medicare codes (92273, 66984, 92014) account for 56.6% of this provider’s total Medicare revenue. Individually those codes represent $104.2K (23.2%), $88.1K (19.7%), and $61.4K (13.7%) respectively, so changes in utilization or reimbursement for these specific services would materially affect overall Medicare revenue. This concentration points to strategic dependence on a few high-value services.

This provider is effectively single‑payer with respect to public programs: lifetime Medicare revenue is $449K and there is no Medicaid billing on file. The absence of Medicaid activity means the practice’s public‑payer exposure is concentrated entirely in Medicare, which reduces diversification of government payer mix and makes Medicare reimbursement and utilization trends particularly consequential for financial planning.

92273 is a standout national outlier for this provider: the code generates $104.2K in revenue from 2.4K claims and the provider ranks #1 of 1106 nationally (100th percentile; extreme outlier). That standing indicates a nationally exceptional throughput for electrophysiologic retinal testing relative to peers and suggests either a local referral base for ffERG/VEP services or specialized testing capacity not common among typical ophthalmology practices.

Several diagnostic and pre‑operative codes show notably above‑typical or extreme volumes, consistent with a practice that performs substantial cataract planning and retinal imaging. For example, 76519 (A‑scan biometry) produced $12.1K and ranks #23 of 1232 providers (98th percentile; extreme outlier), 92133 produced $8.1K and ranks in the 99th percentile (extreme outlier), and 92134 produced $26.5K and ranks in the 95th percentile (notably above typical). These elevated diagnostic volumes align with the provider’s cataract procedural activity and support a workflow that processes many pre‑op measurements and posterior‑segment imaging.

Cataract surgical activity (66984) is present but not extreme: the code produced $88.1K from 222 claims and the provider ranks #5045 of 15965 (68th percentile; typical, unremarkable volume). That places the provider above the median for national peers but not among the highest-volume surgical centers, indicating a steady but moderate surgical caseload that is supported by the high diagnostic throughput.

Tenure and enrollment data show long‑standing Medicare participation: the NPI was enumerated 2006-04-26 (~20 years ago). This duration of enrollment suggests an established practice with a sustained presence in the market, which can support consistent referral relationships for specialized testing and surgical cases.

From an operational risk perspective, the provider’s Medicare revenue concentration combined with no Medicaid billing on file creates vulnerability to shifts in utilization or reimbursement for a few high‑revenue services. Because the top three codes account for 56.6% of Medicare revenue, strategic decisions or external changes affecting electrophysiology, cataract procedures, or comprehensive visits would have outsized financial impact, and the lack of Medicaid activity limits public‑payer diversification as a mitigating factor.
