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

Why is the Medicaid comparison limited to Kansas 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. Kansas (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 reports $1.2M in lifetime Medicare revenue and no Medicaid billing on file, indicating an effectively single‑payer Medicare practice in scope. The NPI was enumerated 2006-03-29 (~20 years ago), so the billing footprint reflects roughly two decades of activity centered on Medicare patients in Emporia, KS.

Revenue is highly concentrated in a small set of radiation therapy codes: the precomputed top three Medicare codes account for 53.1% of total Medicare revenue, driven primarily by G6015 ($472.8K, 38.0%), 78815 ($110.7K, 8.9%), and 77301 ($78K, 6.3%). This concentration signals that a majority of Medicare dollars flow from advanced treatment delivery and PET/CT planning services rather than a broad mix of unrelated outpatient services.

The code mix identifies a specialized therapeutic radiology operation focused on intensity‑modulated and image‑guided radiation therapy. High-volume procedural codes—G6015 (1.8K claims), G6002 (1.4K claims), G6012 (437 claims), and frequent fractionation codes like 77427 (506 claims) and 77336 (508 claims)—are consistent with a practice delivering multi‑session external beam radiotherapy and associated planning/physics support.

Competitive standing is mixed by code: G6015 ranks #119 of 1429 providers nationally (92th percentile) and is described as "typical, unremarkable volume", so oncology IMRT volume is in line with many peers. In contrast, G6002 ranks #53 of 2280 (98th percentile) and 77427 ranks #181 of 4720 (96th percentile), both labeled "notably above typical national volume", indicating above‑average activity in stereoscopic x‑ray guidance and routine radiation therapy delivery relative to national peers.

Several planning and simulation codes also appear at elevated volumes: 77300 (710 claims, $35.5K) ranks #194 of 4719 providers (96th percentile) and 77336 (508 claims, $32K) ranks #127 of 1488 providers (91th percentile). These elevated ranks for dosimetry, simulation, and medical physics suggest the practice performs substantial in‑house treatment planning and weekly physics oversight rather than outsourcing those functions.

Imaging and tracer supplies are meaningful revenue contributors: 78815 generated $110.7K (8.9%) and A9552 contributed $61.2K (4.9%), indicating regular use of PET/CT and FDG tracer in staging or treatment planning. The presence of 78815 at $1075 avg paid/claim and 117 claims for A9552 supports an integrated workflow combining advanced imaging with radiotherapy delivery.

Supportive systemic therapy and infusion codes appear but at low volumes, which implies occasional ancillary services rather than a core chemotherapy program. Examples include 96413 (52 claims, $4.6K total, 24th percentile) and J1454 (16 claims, $5.1K, 1th percentile); these small revenues suggest the provider’s primary business line is radiation therapy with limited drug administration.

Overall, the profile shows an established Therapeutic Radiology physician with concentrated Medicare earnings, high per‑code activity for image guidance and planning, and little to no Medicaid exposure. For payer/provider analysts, this looks like a Medicare‑centric outpatient radiation practice with above‑average national activity in several technical delivery and planning codes but otherwise typical volumes across many IMRT and supportive codes.
