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

Why is the Medicaid comparison limited to Louisiana 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. Louisiana (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 activity is narrowly concentrated in high-cost ophthalmologic therapeutics and associated eye imaging and clinic visits; the top three Medicare codes by revenue account for 85.9% of total Medicare revenue, indicating a practice focused on a small set of procedures rather than broad multispecialty services. The largest single contributor is J2778 (ranibizumab injections), which alone represents 58.9% of Medicare revenue, supported by substantial claim volume.

J2778 is both the dominant revenue driver and a core service line for this clinician: 3.9K claims produced $681.4K in Medicare revenue and the provider ranks #73 of 1208 nationally for this code (94th percentile), reflecting a high but not atypical national volume for ranibizumab injections among peers. This suggests the practice likely operates a high-volume intravitreal injection service for retinal disease management, consistent with an ophthalmology specialty.

The second-largest Medicare item, J2403 (chloroprocaine ophthalmic gel), accounts for 16.5% of the provider’s Medicare revenue with $191.2K reported; the provider ranks #18 of 76 nationally for that code (77th percentile). While the average paid/claim is low, the sizable aggregate revenue and high rank among a much smaller national cohort imply frequent use of topical anesthetic as part of routine ophthalmic procedures or injection preparation.

Evaluation-and-management visits are a meaningful revenue component but concentrated in specific service intensity: 99214 contributes $121K (10.5% of Medicare revenue) from 1.4K claims and ranks as an extreme outlier nationally (#4240 of 479517, 99th percentile). This unusually high volume of 99214 visits relative to national peers indicates an established-patient ambulatory workload that is far above typical national volume and likely reflects regular follow-up visits tied to ongoing retinal treatment regimens.

Imaging and diagnostic codes (92235, 92134, 92250) together represent smaller shares of revenue but show consistently high national percentiles (95th, 90th, and 94th respectively), indicating the provider performs above-typical volumes of fluorescein angiography, retinal OCT interpretation, and fundus photography. This mix reinforces the clinical profile of a retina-focused ophthalmology practice that combines intravitreal injections with diagnostic imaging and documented interpretation.

The provider has no Medicaid billing on file, so payer mix is effectively single-payer Medicare at the patient-coverage level; lifetime Medicare revenue is $1.1M while Medicaid revenue is recorded as none. This lack of Medicaid activity means analyses of in-state Medicaid competition or access patterns cannot be assessed from this dataset.

National competitive standing is mixed: for their primary therapeutic procedure (J2778) the provider sits in the 94th percentile—indicative of a strong national presence for ranibizumab injections—while several E/M codes like 99214 are extreme outliers (99th percentile) in national volume, suggesting an unusually heavy ambulatory follow-up burden compared with peers. Conversely, other procedure ranks (e.g., 67028 at the 65th percentile) are nearer to typical volumes, so the practice is not uniformly dominant across all ophthalmology services.

This clinician has been NPI-enumerated for approximately 20 years (registered 2006-08-02), indicating long tenure in the Medicare program. Combined with the concentrated high-volume procedural profile, the longevity supports an established, procedure-focused ophthalmology practice with sustained referral and follow-up workflows tied to retinal care.
