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

Why is the Medicaid comparison limited to New Hampshire 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. New Hampshire (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 footprint is modest in absolute dollars but concentrated: lifetime Medicare revenue is $471.2K and there is no Medicaid billing on file, so the practice operates effectively as a single‑payer (Medicare) biller in the available data. The absence of any Medicaid claims limits direct conclusions about Medicaid-facing services or market share in the state.

Revenue is highly concentrated in a small set of services: the top three Medicare codes (66984, 99214, 65820) together account for 52.1% of total Medicare revenue. Specifically, 66984 generated $103.4K (21.9%), 99214 generated $85.9K (18.2%), and 65820 generated $56.5K (12.0%), indicating that a majority of earned dollars come from a mix of one major surgical code and high-volume clinic/E&M activity.

The code mix signals a clinical focus on cataract surgery and glaucoma care supported by routine outpatient management. 66984 (cataract extraction with intraocular lens insertion) is the single largest revenue driver, while glaucoma procedures appear across 65820, 65855, 66170 and related codes, suggesting the practice performs both surgical glaucoma interventions and cataract surgery rather than being purely a medical retina or refractive practice.

Diagnostic and imaging services are a pronounced strength: 92133 (OCT imaging) produced $20.9K and ranks #130 of 24968 providers nationally at the 99th percentile, labeled an “extreme outlier, far above typical national volume for this code.” Likewise, 92083 (visual field testing) ranks in the 97th percentile. Together these patterns point to heavy in‑office use of advanced diagnostics to support surgical and medical ophthalmology workflows.

Office visit volumes are high relative to peers, consistent with ongoing medical management and pre/post‑op care: 99214 generated $85.9K and ranks #12478 of 479517 providers nationally (97th percentile; notably above typical national volume), and 99213 also ranks in the 95th percentile. This combination of high E/M and imaging utilization suggests a throughput model with frequent follow‑up visits and diagnostic monitoring.

Competitive standing is mixed by service line: cataract surgery (66984) sits at the 75th percentile (rank #3992 of 15965) and is described as a typical, unremarkable national volume, so the provider is not dominant in cataract procedures nationally. In contrast, the provider is relatively prominent on diagnostic imaging and certain clinic E/M codes (92133 and 99214), where percentile ranks and the supplied labels indicate volumes well above typical national peers.

Tenure and stability in billing are evident: the NPI was enumerated on 2010-04-27 (~16 years ago), indicating an established billing history spanning over a decade. That longevity, combined with the concentrated mix of surgical, diagnostic, and high‑level E/M codes, is consistent with a steady ophthalmology practice that integrates surgery with ongoing outpatient management.

Procedural profile shows selectivity in higher‑complexity services: there are smaller but meaningful contributions from complex cataract work (66982, $14.8K) and trabeculectomy‑type procedures (66170, $14.6K) that are present but not ranked highly nationally (66170 at the 35th percentile). A few codes are at very low national percentiles (for example, 76512 at the 1st percentile), indicating limited or selective use of certain modalities rather than broad, high‑volume adoption across every ophthalmic procedure class.
