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 revenue is essentially single‑payer: total Medicare revenue is $415K and there is no Medicaid billing on file, so Medicare accounts for the entirety of observed public-payer activity. Analysts should treat this profile as Medicare‑centric when assessing payer risk and network value.

Revenue is highly concentrated in a very small set of CPTs: the precomputed top 3 Medicare codes account for 83.2% of this provider's total Medicare revenue, with a single code, 66984, representing $266K or 64.2% of Medicare revenue. That concentration means changes in reimbursement or utilization for those specific services would have outsized effects on the provider’s Medicare earnings.

The mix of top codes indicates a surgical ophthalmology practice focused on cataract care and perioperative diagnostics: 66984 (cataract extraction with IOL insertion), 66982 (complex cataract with IOL), and procedure 92136 (IOL power measurement) are the revenue drivers. Supporting codes in the list such as 66821 (capsulotomy) and 92134/92133 (posterior-segment and optic nerve imaging) reinforce a workflow centered on cataract surgery, post‑op laser capsulotomy, and imaging.

Competitive standing is mixed by service line. For the core cataract procedure 66984 the provider ranks #2271 of 15965 (86th percentile; typical, unremarkable volume for this code), and for complex cataract 66982 ranks #839 of 4580 (81th percentile; typical, unremarkable volume for this code), indicating solid but not dominant national surgical volume; by contrast, biometric measurement 92136 ranks #137 of 8731 (98th percentile; extreme outlier, far above typical national volume for this code), where the provider is a clear national high‑volume outlier.

Evaluation-and-management activity shows a notable imbalance: 99204 (new patient, higher complexity) accounts for $50.5K and 12.2% of Medicare revenue, with 439 claims and a rank of #310 of 227068 (100th percentile; extreme outlier, far above typical national volume for this code). This unusually high volume of comprehensive new‑patient E&M encounters suggests the provider either receives many new consults or documents higher‑level new‑patient visits relative to peers, and it materially contributes to overall Medicare revenue.

Other billed services are smaller contributors and largely reflect routine ophthalmic follow‑up and diagnostics. Examples include 66821 ($14.9K, 3.6% of Medicare revenue; rank #4423 of 10087, 56th percentile; typical, unremarkable volume) and 99214 ($9.7K, 2.3% of Medicare revenue; rank #231020 of 479517, 52th percentile; typical, unremarkable volume), indicating typical levels of post‑op care and established‑patient management.

The provider has an established Medicare presence: NPI enumerated 2014-06-21 (~12 years ago), which supports the interpretation that observed patterns reflect a steady practice rather than a very new entrant. Contracting teams can consider the tenure and the procedural focus (cataract surgery and related diagnostics) when evaluating referral patterns or bundling opportunities.

From a payer perspective, the combination of pronounced revenue concentration (83.2% from the top 3 codes) and the absence of Medicaid billing on file implies both specialization and single‑payer exposure. Risk‑adjusted network planning should account for heavy dependence on a few ophthalmic procedures and the fact that changes in Medicare policy or utilization for these codes could disproportionately affect this provider’s revenues.
