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

Why is the Medicaid comparison limited to Arkansas 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. Arkansas (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 constitutes the measurable revenue footprint: total Medicare revenue is $1.5M while there is no Medicaid billing on file, so the available payer data make this effectively a Medicare-only profile for network and utilization analysis. The absence of Medicaid claims means in-state Medicaid exposure is nil in the dataset and any risk or contracting considerations should be driven by Medicare patterns.

Revenue is highly concentrated in a very small set of services: the precomputed top three Medicare codes (78815, Q3001, 37243) together account for 65.8% of the provider’s Medicare revenue. Individually those codes are 78815 ($434.7K, 30.6%), Q3001 ($336.3K, 23.7%), and 37243 ($163.4K, 11.5%), indicating a narrow high-revenue mix.

The CPT/HCPCS mix points to a specialized interventional radiology and interventional oncology practice model: high-revenue PET/CT imaging codes (78815, 78816, 78814) and radiopharmaceutical supply codes (Q3001, A9552) combined with embolization (37243) and image‑guided access procedures (36561) suggest the provider delivers both diagnostic nuclear medicine and therapeutic/interventional services. Operationally this implies reliance on high-cost consumables and imaging throughput alongside procedural intervention.

On competitive standing for PET/CT and radiotracer services, the provider appears to operate well above typical national volumes: 78815 ranks #336 of 6566 providers nationally (95th percentile) and A9552 ranks #95 of 2411 providers nationally (96th percentile), both labeled notably above typical national volume. These positions indicate the provider is a substantial national-level participant in PET/CT imaging and radiopharmaceutical administration rather than a modest local operator.

Interventional procedure volumes show a mixed competitive picture: central venous access 36561 is an extreme outlier (rank #30 of 3475, 99th percentile), indicating very high national activity in tunneled catheter placement, while embolization 37243 sits at rank #76 of 271 (70th percentile), which is typical to above-typical but not dominant. This combination suggests a practice that is particularly active in device placement and vascular access, with solid but less exceptional performance in embolization procedures.

Several additional codes are flagged as notably above typical nationally (71260 at the 97th percentile, 38222 at the 97th percentile, 77012 at the 98th percentile), reinforcing that the provider’s high volumes extend beyond a single line to multiple imaging and procedure supervision services. For payers, that pattern signals predictable high utilization of imaging supervision and procedural support services when this provider is in-network.

Tenure-wise the provider’s NPI was enumerated on 2012-04-05 (~14 years ago), indicating an established practice history in the Medicare data; combined with the concentrated revenue and several high national percentiles, this suggests sustained operational focus on the identified service lines rather than a transient billing pattern.

From a contracting and utilization-management perspective, the combination of a narrow revenue base (65.8% from top three codes), high-cost radiopharmaceuticals (Q3001, A9552), and multiple codes flagged as notably above typical or extreme outlier may warrant targeted provider-level arrangements or focused utilization reviews. Payers should consider service-line specific terms (imaging throughput, radiopharmaceutical procurement, and tunneled catheter procedures) because these areas drive the majority of the provider’s Medicare revenues.
