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

Why is the Medicaid comparison limited to Texas 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. Texas (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 business is highly concentrated: total Medicare revenue is $4.5M and the top three Medicare codes by revenue account for 84.9% of that total, with J2778 alone generating $3.2M (70.6% of Medicare revenue). Such concentration indicates the practice’s economics are critically dependent on a single drug/administration code.

The CPT/HCPCS mix is consistent with a high‑volume retina injection clinic: J2778 (17.8K claims, $179 avg paid/claim) and procedure code 67028 (3.6K claims, $92 avg paid/claim) together dominate billings, and 92134 (5.3K claims, $29 avg paid/claim) shows very high OCT imaging volume. These patterns point to routine, repeat intravitreal drug delivery supported by frequent diagnostic retinal imaging and E&M visits rather than a broad general ophthalmology practice.

On competitive standing for the drug code, the provider is a national outlier for ranibizumab billing: J2778 ranks #2 of 1208 providers (100th percentile; extreme outlier, far above typical national volume for this code). That rank signals unusual national scale in ranibizumab administration relative to peers.

Other high‑volume codes also show exceptional positioning: 67028 ranks #48 of 4255 providers (99th percentile; extreme outlier) and 92014 ranks #31 of 35415 providers (100th percentile; extreme outlier), indicating the provider is far above typical national volumes for intravitreal injections and established comprehensive eye exams. These percentiles reinforce that both the procedural and E&M sides of the retina practice run at unusually high throughput.

Drug mix is heavily skewed toward ranibizumab billing with relatively limited aflibercept activity: J0178 appears 190 claims and $126.2K revenue (2.8% of Medicare revenue) and is described as typical/unremarkable volume (18th percentile). The contrast between the extreme outlier status of J2778 and the typical standing of J0178 indicates a clear billing concentration on ranibizumab rather than parity across anti‑VEGF agents.

Ancillary diagnostic and procedure codes show a full retina service line beyond injections: fluorescein angiography 92235 (652 claims, $104 avg paid/claim, $67.8K; 98th percentile; notably above typical national volume) and fundus photography 92250 (687 claims, $25 avg paid/claim, $17.2K; 97th percentile; notably above typical national volume) support high diagnostic throughput. Surgical retina codes such as 67113 (35 claims, $1028 avg paid/claim, $36K; 90th percentile) and vitrectomy codes 67042/67040 appear at modest volumes, indicating the practice performs some surgical retina procedures but primarily operates as an injection/imaging center.

Payer mix is effectively single‑payer Medicare: the record shows $4.5M in Medicare revenue and no Medicaid billing on file, so the provider’s publicly available billed revenue and volume are concentrated in Medicare. That concentration should be considered when benchmarking reimbursement risk, patient mix, and growth opportunities outside Medicare.

The provider has a long tenure in the NPI file (enumerated 2006-05-01, ~20 years), supporting the interpretation of an established referral and treatment infrastructure that could sustain repeat injection volumes and high imaging throughput. Long enumeration alongside extreme outlier injection volumes suggests a stable, mature retinal practice rather than a short‑term billing spike.
