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

Why is the Medicaid comparison limited to Tennessee 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. Tennessee (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 is effectively a Medicare-only radiation oncology practice: lifetime Medicare revenue is $2.1M while there is no Medicaid billing on file, so Medicare represents the entirety of recorded public program revenue for this NPI. Analysts should treat payer mix as single-payer Medicare for public-program billing comparisons.

Revenue is highly concentrated in a single technical proton therapy code: 77523 accounts for $1.8M and 82.6% of this provider's Medicare revenue, and the precomputed top-three codes together account for 94.7% of total Medicare revenue, indicating an extreme concentration in a very narrow set of radiation therapy services. This suggests the practice’s operations are dominated by a specific radiotherapy modality rather than broad ambulatory oncology care.

The code-level mix confirms a specialized radiation oncology operation focused on advanced external beam modalities: dominant use of 77523 (proton beam technical component) together with IMRT (77301) and stereotactic body radiation therapy fractions (77373) implies the provider primarily delivers high-complexity, device-driven radiation treatments rather than general medical management or high-volume primary care E/M services.

Competitive standing for the top revenue-driving service is well above typical national volume: 77523 ranks #5 of 111 providers nationally (96th percentile) and is described as notably above typical national volume, identifying this NPI as a major national-volume provider of that specific proton-therapy technical service. By contrast, 77301 (IMRT) and 77373 (SBRT single fraction) are at more typical volumes (78th and 49th percentiles respectively), indicating leadership concentrated on the proton-therapy component rather than across multiple advanced modalities.

Activity level and tenure support an established, specialized practice: the NPI was enumerated ~19 years ago (2007-05-25), so the provider has an extended presence in the Medicare program, which may reflect longstanding access to high-cost radiotherapy infrastructure that drives the large share of revenue from technical proton services.

Several routine radiation therapy and E/M codes appear only at modest volume and revenue relative to the dominant proton code: codes such as 77014 ($180.2K, 8.4% of Medicare revenue), 77427 ($32K, 1.5%), and a range of E/M codes (99205, 99214, 99215, 99213) together make up a small fraction of billed services, underscoring that direct patient evaluation revenue is secondary to device-driven treatment billing.

The provider’s national ranks vary widely across codes, indicating a mixed competitive footprint: while 77523 places the provider among the top national billers for that procedure, other codes like 77014 rank in the 97th percentile of many more providers (118 of 4303) suggesting high volume there as well, but several planning and physics codes (e.g., 77301 rank #804 of 3815 and 77336 rank #553 of 1488) sit at typical percentiles, signaling that outside of proton delivery the provider’s volumes are less exceptional.

Given the preponderance of technical radiation delivery revenue and practically no Medicaid billing, downstream business implications include concentration risk tied to access to proton-beam capacity and Medicare reimbursement policy: any changes in coverage, reimbursement, or referral patterns for proton services could materially affect this provider’s revenue profile because 77523 alone comprises the majority share of Medicare receipts.
