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

Why is the Medicaid comparison limited to Michigan 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. Michigan (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: lifetime Medicare revenue is reported as $2.2M while there is none (no Medicaid billing on file), indicating an effectively single‑payer Medicare practice without observable Medicaid activity. That payer concentration suggests the provider’s patient base and revenue stream are heavily dependent on Medicare beneficiaries rather than a mixed payer panel.

Revenue is highly concentrated in three codes: the top 3 Medicare codes (J0178, J2778, 99214) account for 82.7% of this provider’s total Medicare revenue. J0178 alone represents 43.9% of Medicare revenue and J2778 represents 32.8%, signaling that anti‑VEGF injections are the primary revenue drivers for the practice.

The code mix confirms a retina‑focused procedural practice model: large volumes of intravitreal injection codes (J0178: 1.4K claims, $687 avg paid/claim; J2778: 3.9K claims, $180 avg paid/claim) and the isolated intravitreal injection code 67028 (1.4K claims) indicate routine, high‑throughput office‑based injection services consistent with retinal disease management. High use of retinal imaging (92134) and procedure codes further supports a workflow centered on diagnosis and serial treatment of retinal conditions.

Competitive standing by code is mixed: J2778 ranks #71 of 1208 providers nationally (94th percentile), indicating notably elevated national volume for ranibizumab compared with peers, while J0178 ranks #913 of 3204 (71st percentile), which is a more typical volume position. The practice’s high national rank on J2778 suggests it is a comparatively major user of that drug in the national retina cohort, whereas its aflibercept volume is within the typical peer range.

Office visit coding is an outlier: 99214 has 1.4K claims, $89 avg paid/claim and ranks #4073 of 479517 providers nationally (99th percentile) and is labeled an extreme outlier. This combination of very high‑volume moderate‑complexity E/M visits alongside high injection volume implies substantial face‑to‑face throughput for established patients, potentially reflecting frequent follow‑up visits tied to treatment protocols.

Diagnostic imaging and certain procedures are notably above typical: 92134 has 2.1K claims, $28 avg paid/claim and ranks #990 of 26868 providers nationally (96th percentile), described as notably above typical national volume, while 67028 ranks in the 78th percentile. These elevated imaging and procedure percentiles corroborate a clinical focus on retinal diagnosis, monitoring, and in‑office therapeutic interventions.

Tenure data show the NPI was enumerated on 2012-04-18 (~14 years ago), indicating the provider has been enrolled in Medicare for over a decade. That length of enrollment supports interpretation of the billing profile as an established practice pattern rather than a nascent or transient billing spike.

The practice’s business risk profile includes concentration by both payer and service line: reliance on Medicare ($2.2M) with no Medicaid revenue on file creates exposure to Medicare policy and utilization shifts, while dependency on a small set of high‑revenue codes (top 3 = 82.7%) centers revenue around anti‑VEGF therapy and associated visits. For payers and network planners, these patterns point to a high‑volume retina injection clinic that would be sensitive to changes in drug utilization, reimbursement, or beneficiary mix.
