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

Practice profile and service mix indicate a cataract-focused ophthalmology operation: the provider’s top revenue code is 66984 (559 claims, $346 avg paid/claim, $193.4K revenue) which accounts for 63.7% of Medicare revenue, and other high-revenue codes include 66821 and 66982, all of which are cataract-related procedures. The presence of 65756 (full corneal transplant) and frequent billing for 92136 (biometry) shows this provider also performs advanced anterior-segment surgery and routine preoperative measurements, suggesting a surgical ophthalmology practice that pairs cataract volume with corneal work and biometric services.

Revenue concentration is high: the precomputed top-3 Medicare codes account for 81.1% of this provider’s total Medicare revenue, indicating that a small set of procedures—dominated by 66984 at $193.4K (63.7%)—drive the majority of billed Medicare dollars. That level of concentration implies financial sensitivity to changes in cataract surgery volume, reimbursement, or referral patterns.

Payer mix is effectively single-payer in this dataset: lifetime Medicare revenue is $303.2K while there is no Medicaid billing on file, so the provider’s publicly reported activity is concentrated entirely in Medicare. For payer strategy and network negotiations, this profile should be treated as a Medicare-dependent billing footprint with no Medicaid claims to benchmark against.

Competitive standing by code is mixed: for high-revenue cataract extraction with IOL insertion (66984) the provider ranks #2716 of 15965 nationally (83th percentile), which we interpret as a solid but not dominant national volume for that code. Several other cataract-related codes (66821 rank #2341 of 10087, 66982 rank #1386 of 4580, 66991 rank #448 of 1445) fall in mid-to-upper percentiles (roughly 68–77th percentile) and are described as typical or unremarkable national volumes, supporting the view of a competent regional surgical practice rather than a top-tier national center.

One clear statistical outlier is 92136 (biometry): 635 claims, $30 avg paid/claim, $19.1K revenue, where the provider ranks #371 of 8731 nationally (96th percentile). That “notably above typical national volume” standing for biometry suggests either a heavy reliance on preoperative diagnostic billing or systematic measurement of surgical candidates, which can be an operational strength for a cataract-centric practice.

Specialty and capability signal: the presence of 65756 (26 claims, $810 avg paid/claim, $21.1K revenue) indicates the provider performs corneal transplant procedures and ranks #186 of 567 nationally (65th percentile); while this rank is not dominant, the code’s inclusion in the top revenue mix shows capability in complex anterior-segment surgery beyond routine cataract cases. This diversification into corneal surgery may support referral capture for more complex cases locally.

Tenure and stability: the NPI was enumerated 2015-06-08 (~11 years ago), indicating an established presence in the market long enough to build a surgical practice and referral network. Given the concentrated Medicare revenue and multi-year enumeration, the current billing profile likely reflects an operational specialty practice rather than a recent episodic billing spike.

Operational implications for payers and analysts: because a single procedure (66984) represents a majority of Medicare revenue and the top three codes account for 81.1% of Medicare revenue, payer review or contracting should focus on cataract service lines and associated pre/post-op coding (including 92136 biometry and 66821 YAG capsulotomy). The absence of Medicaid billing also means state Medicaid utilization benchmarks and competitively relevant Medicaid peer comparisons are not available for this provider.
