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

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

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

JOHN PURVIANCE is a radiation oncology physician in Casper, WY with total Medicare revenue of $2.5M and no Medicaid billing on file (none below), indicating an effectively single‑payer Medicare practice at the dataset level. The provider's NPI was enumerated on 2007-03-30 (~19 years ago), reflecting long tenure in the Medicare program which supports established referral and treatment operations.

Revenue is highly concentrated in a few technical oncology services: the precomputed top three Medicare codes account for 50.6% of total Medicare revenue, led by 78815 (23.9%), G6015 (16.3%), and 77301 (10.5%). These three codes alone generate roughly half of the provider's Medicare dollars, signaling reliance on high-volume imaging and IMRT treatment delivery for revenue.

The code mix points to an advanced radiation oncology service line with integrated PET/CT imaging and modern IMRT workflows. High-revenue imaging and radiopharmaceutical codes — 78815 ($589.7K), A9596 ($252.8K), and A9552 ($123.3K) — alongside planning and delivery codes such as 77301 ($259.4K), G6015 ($401.8K), and 77338 ($70.7K) indicate on‑site or closely coordinated diagnostic PET capability plus high-capacity IMRT planning and delivery.

At the national level this provider ranks as a major outlier on multiple technical radiation codes: 77301 ranks #3 of 3815 providers nationally (100th percentile; extreme outlier), 77338 ranks #4 of 3807 (100th percentile; extreme outlier), and 78815 ranks #67 of 6566 (99th percentile; extreme outlier). These rankings suggest the provider is among the highest-volume US practitioners for IMRT planning/delivery and PET/CT imaging rather than a modest regional participant.

Not every line is extreme: several high-use codes are characterized as typical or unremarkable in volume (for example, G6015 ranks #204 of 1429 providers nationally (86th percentile; typical, unremarkable volume), A9596 ranks #31 of 168 providers nationally (81th percentile; typical, unremarkable volume), and 77373 ranks #127 of 454 providers nationally (72th percentile; typical, unremarkable volume)). This mix of extreme outlier activity on core IMRT and imaging codes with typical volumes on other related codes suggests focused specialization rather than uniformly elevated billing across all radiation therapy services.

Operational metrics show high procedural throughput for both imaging and treatment-delivery technical components: examples include 3.6K claims for 77014 ($159.5K, ranks #33 of 4303, 99th percentile; extreme outlier), 1.1K claims for G6002 ($28.1K, ranks #97 of 2280, 96th percentile; notably above typical), and substantial counts for planning/dosimetry codes like 77290 (210 claims, $34.2K, ranks #27 of 3650, 99th percentile; extreme outlier). These volumes are consistent with a practice that delivers many fractions and performs routine simulation/verification and image‑guided workflows.

Clinical capability is further evidenced by use of specialized radiopharmaceuticals and advanced imaging: A9596 (Gallium ga-68 gozetotide) shows 302 claims and $252.8K in revenue, and A9552 (FDG F-18) shows 434 claims and $123.3K in revenue. The presence and scale of these tracer codes, combined with top-tier national rank on PET/CT code 78815, support a practice offering advanced PET imaging services as part of cancer staging and treatment planning.

The pure Medicare revenue base ($2.5M) combined with no Medicaid billing (none below) implies payer concentration risk and positions Medicare as the dominant contract and utilization driver for this provider. Analysts should treat competitive and reimbursement changes in Medicare as primary factors that will materially affect this provider's revenue profile given the absence of Medicaid activity in the reported data.
