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

Why is the Medicaid comparison limited to Arizona 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. Arizona (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

Revenue concentration is highly concentrated in a single radiopharmaceutical: Total Medicare revenue of $4M is driven overwhelmingly by A9607, which accounts for $3.5M (85.4% of the provider’s Medicare revenue) and is one of the precomputed top‑3 codes that together represent 92.4% of Medicare revenue. This level of concentration indicates that the provider’s Medicare financial performance is largely dependent on reimbursement and utilization of A9607.

Service-line profile shows a combined radiopharmaceutical and advanced external-beam practice: A9607 (Lutetium lu 177 vipivotide tetraxetan) dominates revenue ($3.5M; 17.9K claims), while G6015 (707 claims, $191.6K) and 77301 (66 claims, $90.6K) indicate active use of intensity-modulated and advanced treatment delivery techniques. The mix of a high-volume Lu‑177 therapeutic code with IMRT planning/delivery codes and stereotactic-related codes (G0340, G0339) suggests an operation that pairs systemic radiopharmaceutical therapy with complex external-beam radiation services.

Payer mix is effectively single-payer Medicare: the profile shows Total Medicare revenue of $4M and no Medicaid billing on file, so this provider operates with Medicare as the primary (and only recorded) public payer. Analysts should treat Medicaid exposure as nil in in‑state peer comparisons and focus competitive and utilization analysis on Medicare dynamics.

Competitive standing is strong for the lead radiopharmaceutical code but modest or typical across most external-beam codes: A9607 ranks #7 of 44 nationally (86th percentile; described as typical, unremarkable volume for this code), making the provider one of the higher-ranked users nationally for that drug while still falling within peer expectations. By contrast, G6015 ranks #560 of 1429 (61th percentile; typical, unremarkable volume) and 77301 ranks #676 of 3815 (82th percentile; typical, unremarkable volume), indicating more routine national standing across IMRT and delivery codes.

Tenure is long-standing: the NPI was enumerated on 2006-02-20 (~20 years ago), which supports interpretation of these billing patterns as the output of an established practice rather than a recent entrant. Longevity may influence referral relationships and capacity to deliver high-cost radiopharmaceutical therapies at scale.

There are specific statistical outliers in non-radiopharmaceutical services that warrant attention: 99205 (91 claims, $14.8K revenue) ranks #3999 of 66257 providers nationally (94th percentile) and is labeled notably above typical national volume, indicating above-average high-complexity new patient E&M billing relative to peers. Conversely, several procedure codes (e.g., G0340 at rank #99 of 122, 17th percentile; G6012 at rank #716 of 868, 17th percentile) are characterized as typical or low relative volumes, showing mixed intensity across technical service lines.

Operational risk and business implications from drug dependence: with A9607 constituting $3.5M of the $4M Medicare total, any change in access, reimbursement, or clinical guidelines for Lutetium lu 177 vipivotide tetraxetan would likely have outsized impact on revenue. Contracting, inventory management, and payer policy monitoring for this specific radiopharmaceutical should be prioritized in payer-provider negotiations and utilization management.

Presence of niche or unique billing events suggests occasional diverse procedures: small-volume but distinctive codes appear in the profile (for example, 67120: 12 claims, $5.1K revenue, ranks #1 of 1 nationally with no peer comparison available), plus single-session radiosurgery codes (G0339, 11 claims, $9.7K). These entries point to episodic, specialized services beyond the core Lu‑177 treatments that may reflect either ancillary capabilities or rare casework rather than a major revenue stream.
