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

GREGORY MCCORMICK is an Ophthalmology Physician in SOUTH BURLINGTON, VT with an NPI enumerated on 2006-05-15 (~20 years ago) and lifetime Medicare revenue of $282.6K. There is no Medicaid billing on file for this provider, so Medicare is the sole public payer represented in the dataset.

Revenue is highly concentrated in a small set of services: the precomputed top 3 Medicare codes by revenue account for 80.3% of this provider's total Medicare revenue. The single largest line item is 66984 (3.3K claims, $54 avg paid/claim, $177.2K revenue), which alone represents 62.5% of Medicare revenue, followed by 99204 ($30.8K revenue, 10.9% of total) and 66821 ($19.7K revenue, 6.9% of total).

The code mix indicates a practice centered on cataract surgery and its perioperative workflow: 66984 (phacoemulsification with intraocular lens insertion) is the dominant procedure and is complemented by 66821 (YAG capsulotomy) and 92136 (biometry, 445 claims, $13.8K revenue). These elements together suggest the provider routinely performs cataract operations and associated pre‑ and post‑operative diagnostics and laser follow-up rather than a broad mix of general ophthalmic subspecialty procedures.

Competitive standing by code shows above‑typical national activity for the top revenue drivers: 66984 ranks #407 of 15965 providers nationally (97th percentile; notably above typical national volume for this code), and 99204 ranks #1540 of 227068 providers nationally (99th percentile; extreme outlier). By contrast, 66821 ranks #3203 of 10087 providers nationally (68th percentile; typical, unremarkable volume), indicating that while cataract extraction volume is high, some follow‑on or complex procedure rates are closer to typical peer levels.

High-volume, high-acuity office visits are a meaningful revenue contributor: 99204 appears as a prominent non‑procedural code (285 claims, $108 avg paid/claim, $30.8K revenue) and is labeled an "extreme outlier," which is consistent with heavy new‑patient consults or referral evaluations that may feed surgical volume. This pattern implies significant intake of new surgical or consult patients, which has operational implications for clinic throughput and referral relationships.

Ancillary and diagnostic services show mixed but generally typical volumes: comprehensive established exams (92014: 208 claims, $17.3K revenue, 6.1% of Medicare revenue) and imaging codes such as 92134 and 92133 appear at routine percentiles (68th and 57th respectively), supporting a practice that couples surgical throughput with standard diagnostic follow‑up rather than high volumes of advanced imaging.

The provider’s surgical complexity mix is skewed toward standard cataract technique: 66982 (complex extracapsular cataract with devices, 14 claims, $7.5K revenue, 2.6% of Medicare revenue) ranks #4187 of 4580 providers nationally (5th percentile; typical, unremarkable volume), suggesting limited use of more complex cataract procedures or devices relative to peers. This concentration in standard phacoemulsification (66984) with lower rates of complex technique has implications for case mix, equipment needs, and referral patterns.

From a payer‑strategy and access perspective, the absence of any Medicaid billing on file combined with $282.6K in Medicare receipts means the provider effectively operates with a single public‑payer footprint in this dataset. That concentration may matter for contract negotiations, network adequacy assessments, and analyses of the provider’s service availability to lower‑income populations in Vermont.
