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

Why is the Medicaid comparison limited to Vermont 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. Vermont (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

This provider’s billed Medicare activity totals $361.1K in lifetime revenue and there is no Medicaid billing on file; the profile is therefore effectively single‑payer with Medicare as the dominant revenue source. The absence of Medicaid claims suggests the practice’s Medicare exposure defines most of its payer mix and reimbursement risk.

Revenue is highly concentrated in a small set of services: the precomputed top three Medicare codes (66984, 92014, 99214) collectively account for 73.7% of this provider’s total Medicare revenue. Individually those codes are 66984 ($132.3K, 36.6%), 92014 ($93.4K, 25.8%), and 99214 ($40.5K, 11.2%), indicating that a small bundle of surgical and office/E&M services drives most receipts.

The code mix points to a hybrid surgical and comprehensive outpatient ophthalmology practice: cataract extraction with intraocular lens insertion (66984) is the single largest revenue driver, while comprehensive established eye exams (92014) and higher‑level E&M visits (99214) generate the next largest shares. Supporting services such as YAG capsulotomy (66821, $13.6K) and intraocular lens power measurement (92136, $4.9K) indicate routine postoperative and preoperative workflows tied to cataract care.

Competitive standing by code is mixed: the provider is a notably high‑volume national outlier for comprehensive established eye exams (92014 ranks #1173 of 35415 providers nationally, 97th percentile; "notably above typical national volume") and for OCT imaging (92133 ranks #852 of 24968 providers nationally, 97th percentile; "notably above typical national volume"). By contrast cataract surgery 66984 is in the 75th percentile (ranks #3976 of 15965; described as "typical, unremarkable volume"), and complex cataract cases 66982 are lower (39th percentile), signaling strong office and diagnostic throughput with moderate surgical volumes.

Diagnostic testing is a clear emphasis in the practice’s mix: 92133 (computerized optic nerve imaging) appears as a high‑volume diagnostics line with 446 claims, $24 avg paid/claim, and $10.7K revenue (3.0% of Medicare revenue) that ranks in the 97th percentile nationally. Visual field testing and extended exams (92083 and 92004) also contribute meaningfully, supporting an infrastructure oriented to ophthalmic imaging and functional testing in addition to procedures.

The surgical portfolio shows both routine and more complex procedures but with asymmetric volumes: routine phacoemulsification with IOL insertion (66984) dominates surgical revenue at $132.3K (36.6% of Medicare revenue), while complex intraocular lens procedures (66982, $13.4K) and secondary laser capsulotomy (66821, $13.6K) appear as smaller, targeted service lines. This mix suggests a practice that performs a steady caseload of routine cataract surgery with occasional complex cases and the expected post‑op interventions.

Tenure on Medicare is long: the NPI was enumerated on 2006-05-30 (≈20 years ago), which is consistent with an established practice pattern and the accumulated lifetime billing profile observed here. Long enumeration combined with concentrated Medicare revenue implies entrenched referral or patient-flow relationships within the Medicare population.

The lack of any Medicaid billing on file makes this provider effectively single‑payer (Medicare) in the available data; that concentration reduces exposure to Medicaid reimbursement variability but also signals a narrower insured patient mix. For analysts, this is an important consideration when modeling payer diversification, access to lower‑income populations, or sensitivity to Medicare policy changes.
