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

Why is the Medicaid comparison limited to Washington 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. Washington (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.

Key Findings

This provider bills almost exclusively to Medicare (Total Medicare revenue: $1.9M) and has no Medicaid billing on file, making its Medicare book of business the de facto single payer for observed claims. The absence of any Medicaid activity on file indicates payer mix is effectively single-payer and concentrated in Medicare reimbursement streams.

Revenue is extremely concentrated in intravitreal anti-VEGF therapy: the precomputed top 3 Medicare codes by revenue account for 86.3% of this provider's total Medicare revenue, with J0178 responsible for $1.4M (74.2%) alone. That concentration means the provider’s overall Medicare income is heavily dependent on continued utilization and reimbursement of that single drug code.

The procedure and drug mix is consistent with a retina specialist practice that focuses on frequent intravitreal injections and high-volume retinal imaging: J0178 (aflibercept) shows 2.1K claims at $682 avg paid/claim, J2777 (faricimab) shows 3.5K claims at $29 avg paid/claim, and J2778 (ranibizumab) contributes additional drug revenue. Diagnostic and management activity is evident from 92134 (1.7K claims, $51.9K) and E/M coding such as 99214 (999 claims, $89.9K), supporting a workflow of recurrent injections plus retinal imaging and follow-up office visits.

Competitive standing for the top drug is above median but not an extreme outlier: J0178 ranks #489 of 3204 providers nationally (85th percentile) and is labeled as having "typical, unremarkable volume for this code," indicating stronger-than-average use of aflibercept relative to peers but not dominance. By contrast, J2777 (rank #1761 of 2039, 13th percentile) is lower-ranked and characterized as "typical, unremarkable volume," signaling that use patterns for other anti-VEGF agents diverge from the provider's primary revenue driver.

Clinical encounter and imaging volumes stand out relative to national peers: 99214 ranks in the 98th percentile and is described as "notably above typical national volume for this code," while 92134 ranks in the 95th percentile and is also labeled "notably above typical national volume for this code." These high percentiles for E/M and retinal imaging suggest the practice manages a larger-than-typical panel of follow-up, established ophthalmology patients who require ongoing monitoring.

Other services and revenue streams are secondary: J7999 (compounded drug) produced $43.8K from 617 claims and is ranked in the 92th percentile with a "typical, unremarkable volume" label, while cataract-related code 66984 generated $23.1K from 55 claims and ranks in the 35th percentile. This pattern implies compounded medications and occasional cataract procedures exist in the practice mix but do not materially offset dependence on anti-VEGF therapy.

The provider’s utilization profile exposes operational sensitivity to changes in ophthalmic drug utilization or reimbursement: with J0178 accounting for $1.4M of the $1.9M Medicare revenue and the top three codes making up 86.3% of revenue, shifts in drug selection, payer pricing, or clinical guidelines for injections would materially affect revenue. Given the heavy reliance on a single high-revenue drug code, payers and network managers should monitor drug-specific utilization trends and prior authorization impacts.

The provider has an established Medicare presence, with an NPI enumerated 2013-06-25 (~13 years ago), supporting the interpretation that the observed high-volume injection, imaging, and follow-up visit pattern represents an ongoing retina-specialty practice rather than a transient billing artifact. Tenure combined with sustained high percentiles on 99214 and 92134 indicates persistent clinical volume rather than a short-term spike.
