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

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

Key Findings

This provider’s Medicare billing is the sole payer activity on file: Total Medicare revenue is $268K and there is no Medicaid billing on file. That makes the practice effectively single-payer (Medicare) in the available claims data, leaving it exposed to Medicare-specific reimbursement and referral dynamics rather than a mixed Medicaid/Medicare panel.

Revenue is highly concentrated in a very small set of services: the precomputed top three Medicare codes account for 76.6% of the provider’s total Medicare revenue. Those top three are 66984 (52.2% of Medicare revenue, $139.9K), 66821 (14.7%, $39.3K), and 99204 (9.7%, $26K), indicating the bulk of dollars come from a narrow surgical and evaluation mix.

The code mix points to a cataract-focused ophthalmology practice with associated pre- and post-operative care: 66984 (cataract extraction with IOL) is the largest single revenue driver at $139.9K with 415 claims, and related procedures 66821 (YAG capsulotomy) and 66982 (complex cataract/IOL at $24.8K with 53 claims) together reinforce a surgical service line. High-volume diagnostic/support codes such as 92136 (738 claims, $11.8K) and 92134 (425 claims, $10.2K) further support a workflow centered on surgical planning and retinal imaging.

Competitive standing for core surgical codes is modest to typical rather than dominant: 66984 ranks #3284 of 15965 providers nationally (79th percentile; typical, unremarkable volume for this code), 66821 ranks #967 of 10087 (90th percentile; typical, unremarkable volume), and 66982 ranks #980 of 4580 (78th percentile; typical, unremarkable volume). These ranks indicate the provider performs cataract surgery at volumes that are above median but not at the level of national high-volume surgical centers.

The provider is an outlier on at least one evaluation-and-management measure: 99204 accounts for $26K and 228 claims (9.7% of Medicare revenue) and is labeled an "extreme outlier" at the 99th percentile (#3294 of 227068 providers; extreme outlier, far above typical national volume for this code). This suggests unusually high use of moderate-complexity new-patient visits relative to peers, which may reflect referral-driven new-patient intake or local practice patterns around surgical consults.

Diagnostic and pre-operative testing is used at above-typical rates: 92136 (biometry) has 738 claims and $11.8K in revenue and ranks #251 of 8731 providers (97th percentile; notably above typical national volume), and 92134 (retinal imaging) has 425 claims and $10.2K and ranks #3906 of 26868 (85th percentile; typical, unremarkable volume). The elevated percentile for 92136 in particular reinforces that biometry for IOL planning is a routine, high-volume part of this provider’s workflow.

Overall revenue scale is relatively small in absolute terms: lifetime Medicare revenue of $268K indicates a modest Medicare footprint despite the concentrated surgical focus. Coupled with no Medicaid billing on file, the practice appears to operate with a limited Medicare panel or a low volume of high-revenue events rather than a large, diversified payer base.

The provider has an established tenure in the NPI file, enumerated 2006-05-15 (~20 years ago), which implies a long-standing local presence. That longevity, together with concentrated cataract-related billing and elevated new-patient E/M and biometry volumes, suggests entrenched referral and surgical workflows rather than a newly built service line.
