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

Why is the Medicaid comparison limited to South Dakota 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. South Dakota (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 Medicare portfolio is concentrated around cataract care and associated ophthalmic evaluation: total Medicare revenue is $511.4K and the top 3 Medicare codes by revenue account for 78.6% of that total, led by 66984 (60.2% of Medicare revenue, $307.7K). The code mix—high shares for 66984 and presence of 66982, 66991, and biometry codes—signals a practice that generates most of its income from cataract surgery and implant-related services.

Operationally the practice shows an unusually high volume of pre‑ and peri‑operative diagnostic work: 92136 appears 999 times with $27 avg paid/claim and ranks #102 of 8731 providers nationally (99th percentile; extreme outlier, far above typical national volume for this code), and 76519 is also present for A‑scan biometry. Paired with the large 66984 surgical revenue, this pattern is consistent with a workflow that performs many cataract cases and absorbs most preoperative testing in‑house rather than outsourcing.

Referral and new‑patient throughput appears exceptionally strong: 92004 generated 470 claims at $98 avg paid/claim and $46.1K revenue, ranking #136 of 26467 providers nationally (99th percentile; extreme outlier, far above typical national volume for this code). That extreme outlier status for a comprehensive new‑patient ophthalmology visit suggests the provider either receives a steady stream of new cataract or complex anterior segment referrals or has a billing pattern that captures initial comprehensive evaluations at higher frequency than peers.

Despite the surgical emphasis, the provider is not a dominant national cataract surgeon by procedure volume: 66984 shows 897 claims at $343 avg paid/claim ($307.7K revenue) and ranks #2097 of 15965 providers nationally (87th percentile; typical, unremarkable volume for this code). Similarly, 66821 (YAG capsulotomy) ranks #1212 of 10087 (88th percentile; typical), indicating solid but not market‑leading procedure volumes when benchmarked against national peers.

The practice shows a limited breadth of higher‑volume subspecialty work but does perform some corneal procedures: 65756 (full endothelial corneal transplant) appears 16 times with $879 avg paid/claim and $14.1K revenue, ranking #412 of 567 providers nationally (23th percentile; typical, unremarkable volume). Low counts and lower national percentile for corneal add‑on codes such as 65757 (16 claims, ranks 14 of 17 providers nationally; 19th percentile) indicate capability for selective corneal surgery but not a high‑volume corneal service line.

Payer mix is effectively single‑payer Medicare: the profile shows $511.4K in Medicare revenue and explicitly reports no Medicaid billing on file. This lack of Medicaid activity means the provider’s commercial/Medicaid access, safety‑net participation, and exposure to dual‑payer revenue streams are minimal or absent, which has implications for network negotiations and local access for Medicaid patients.

Concentration risk is material given the revenue reliance on a few codes: with 78.6% of Medicare revenue tied to the top three codes, changes to reimbursement, referral patterns, or cataract surgical volume would disproportionately affect overall revenue. The practice’s business sensitivity to policy changes or competitive pressure in cataract services should be a key consideration for payers and contracting teams.

The provider has established tenure in the Medicare program, with an NPI enumerated on 2008-03-25 (~18 years ago), indicating a long‑standing presence in the market. Longevity paired with the high new‑patient and biometry volumes suggests sustained local demand and operational stability focused on cataract and anterior‑segment ophthalmology services.
