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

Why is the Medicaid comparison limited to Hawaii 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. Hawaii (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 billing picture is effectively single-payer: Total Medicare revenue is $495.9K and there is no Medicaid billing on file. Analysts should treat this practice as Medicare-focused in scale and exposure rather than balanced across both public payers.

Revenue is highly concentrated in a small set of services: the top three Medicare codes (66984, 92014, 99214) account for 51.7% of total Medicare revenue. Specifically, 66984 represents 25.0% of Medicare revenue with 289 claims, $429 avg paid/claim and $124K revenue; 92014 represents 16.0% with 837 claims, $95 avg paid/claim and $79.5K revenue; and 99214 represents 10.6% with 533 claims, $99 avg paid/claim and $52.8K revenue.

The code mix indicates a cataract-surgery–anchored ophthalmology practice with substantial office-based care. High revenue and claim counts for 66984 (cataract extraction with IOL) together with follow-up procedures such as 66821 YAG capsulotomy (66 claims, $261 avg, $17.2K) and frequent comprehensive exams (92014, 837 claims) point to a surgical volume plus associated postoperative and diagnostic services.

One notable statistical outlier on the new-patient side is 99204: 298 claims, $125 avg paid/claim, $37.3K revenue (7.5%) and a rank of #1316 of 227068 providers nationally (99th percentile; extreme outlier). This suggests an unusually high volume of higher-complexity new patient visits relative to national peers, which may reflect referral intake, specialty consults, or clinic triage patterns.

Diagnostic and functional testing are important operational lines: 92083 visual field testing (354 claims, $51 avg, $18.1K) ranks #1364 of 25484 (95th percentile; notably above typical), and imaging codes 92134 (444 claims, $32 avg, $14.2K) and 92133 (427 claims, $29 avg, $12.4K) rank in the 86th and 96th percentiles respectively. The practice also reports 92273 ERG testing (281 claims, $106 avg, $29.8K; 92th percentile), indicating in-house capability for both structural imaging and retinal functional testing.

The provider’s competitive standing is mixed by service line: for cataract extraction 66984 they rank #4133 of 15965 (74th percentile; typical, unremarkable volume), so they are not a dominant national cataract surgeon, but they are notably above typical on comprehensive exams (92014, #2375 of 35415; 93th percentile) and very strong on certain niche procedures such as lacrimal probing 68840 (142 claims, $167 avg, $23.7K; rank #15 of 532, 97th percentile). Overall this suggests a practice that competes strongly on office-based throughput and select procedures rather than by very high-volume cataract surgery alone.

Operational throughput is evident in the high claim counts for lower-paid diagnostic services: 92014 (837 claims), 92202 (870 claims, $13 avg, $11.3K), 92134 (444 claims) and 92133 (427 claims) together imply a high-volume ambulatory workflow where many lower-reimbursement tests and exams aggregate to meaningful revenue. For contracting or network decisions, expect the practice’s revenue to be sensitive to changes in outpatient exam and imaging reimbursement rather than a small number of very high-dollar surgical cases.

The provider is a long-tenured clinician with NPI enumeration date 2006-11-21 (~20 years ago), indicating an established presence in Honolulu, HI; tenure combined with the mix of surgical, diagnostic, and procedure codes suggests a stable clinical practice with a mature referral and follow-up pattern.
