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 revenue is overwhelmingly Medicare-based: lifetime Medicare revenue is $5.9M while Medicaid revenue is listed as none, making the practice effectively single‑payer in the datasets shown. Revenue concentration is extreme — the precomputed top 3 Medicare codes account for 90.1% of total Medicare revenue — which creates operational dependence on a small set of high‑value therapies.

Two lutetium radiopharmaceuticals dominate the book of business. A9607 (Lutetium lu 177 vipivotide tetraxetan) alone generates $3.6M (61.2% of Medicare revenue) and A9513 (Lutetium lu 177, dotatate) generates $1.5M (25.2% of Medicare revenue), signaling that the practice’s principal service line is high‑volume Lu‑177 molecular radiotherapy rather than conventional outpatient primary care or broad ambulatory services.

Competitive standing for the top radiopharmaceutical codes is strong at the national level. For A9607 the provider ranks #6 of 44 nationally (88th percentile) and for A9513 the provider ranks #1 of 2 nationally (100th percentile), which places the clinician among the leading national billers for these specific Lu‑177 therapies even though the dataset labels the volumes as "typical, unremarkable" for those codes.

The remainder of billed activity reflects integrated radiation oncology services supporting complex therapy. G6015 (intensity modulated treatment delivery) contributes $217.2K (3.7% of Medicare revenue) with 749 claims, and a range of planning and physics codes (e.g., 77301, 77338, 77334, 77336) appear throughout the top codes, indicating the practice performs IMRT planning and delivery in addition to radiopharmaceutical administration.

Several procedure codes are statistical high‑end outliers or notably above typical volume, which suggests particular operational strengths. 79101 (radiopharmaceutical injection) ranks #5 of 302 (99th percentile; "extreme outlier") and 77300 and 77470 each rank in the 96th percentile ("notably above typical national volume"), consistent with concentrated, procedure‑intensive activity around radiopharmaceutical and special radiotherapy services.

Imaging and diagnostic billing appears limited relative to peers in at least one area: 78815 (PET/CT) shows only 14 claims for $16.6K and ranks #6107 of 6566 providers nationally (5th percentile), which may indicate reliance on external imaging vendors or lower internal PET/CT throughput despite high Lu‑177 therapy volumes.

The provider’s tenure on file predates many of these therapies: NPI enumeration is 2006-06-02 (~20 years ago), indicating long‑standing Medicare participation that likely supported adoption and scaling of Lu‑177 treatment lines over time.

Because the practice derives the vast majority of its measurable revenue from a narrow set of high‑cost therapies and has no Medicaid billing on record, payers and network analysts should treat this entity as a specialized radiation/radiopharmaceutical provider with concentrated payer exposure and limited Medicaid footprint.
