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 District of Columbia for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to District of Columbia 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. District of Columbia (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

SEAN COLLINS is effectively a Medicare-focused Radiation Oncology Physician with $444.1K in lifetime Medicare revenue and no Medicaid billing on file, indicating a single-payer footprint in available claims data rather than a mixed Medicaid/Medicare practice. The absence of any Medicaid lines means payer-mix analysis should treat this provider as operating solely within the Medicare population for the period covered.

Revenue concentration is high: the precomputed top 3 Medicare codes account for 50.9% of this provider's total Medicare revenue, signaling that a small set of procedures drive more than half of billed Medicare income and suggesting a focused service line. Those top codes include stereotactic body radiotherapy, planning/dosimetry, and other high-value radiation therapy planning/administration services as reflected in the listed CPTs.

Clinical/service-line implications from the code mix show this practice specializes in advanced external-beam radiation services. Heavy use of 77435 (stereotactic body radiotherapy), 77300 (dosimetry/planning), 77295 (3D dose calculation), and IMRT planning codes such as 77301 and 77338 indicates the provider delivers precision radiotherapy (including SBRT and IMRT) and invests in treatment planning and simulation workflows. This mix is consistent with a radiation oncology practice that focuses on high-precision, image-guided treatments rather than general primary care or routine procedural services.

Competitive standing on Medicare is above typical for multiple high-revenue codes: 77435 is an extreme outlier and ranks #1 of 1480 providers nationally (100th percentile), 77295 ranks #13 of 3008 providers nationally (100th percentile), and 77300 ranks #28 of 4719 providers nationally (99th percentile). These rankings indicate the provider operates at a far higher volume for several complex radiation therapy services than most peers and can be characterized as a dominant national outlier for those specific procedures.

For more routine E/M and support codes the provider shows notable activity but less exceptional standing: 99213 generates $32.1K (7.2% of Medicare revenue) and ranks in the 96th percentile nationally, while 99204 is an extreme outlier in volume for new-patient E/M at the 98th percentile. This suggests the practice also receives a steady stream of evaluation/management visits, likely to support the radiation oncology care pathway, though these E/M services are secondary to the high-revenue procedure codes.

Tenure and market presence: the provider’s NPI was enumerated on 2006-07-18 (about 20 years ago), indicating long-standing Medicare enrollment which aligns with the depth of procedure volume observed. Extended enrollment supports an established practice profile and helps explain accumulation of the reported lifetime Medicare revenue and high national ranks on specific radiation therapy codes.

Statistical outlier characterization: several codes are explicitly labeled "extreme outlier" or "notably above typical," and those labels are reflected in the data—77435, 77295 and 77300 are described as extreme outliers or far above typical national volume, while multiple other planning and simulation codes (77263, 77301, 77290) are at or above the 95th percentile. This pattern points to concentrated, exceptionally high activity in advanced radiation therapy planning and delivery compared with national peers.

Operational implication for payers and network analysts: given the concentration in high-complexity radiation services and the absence of Medicaid billing, payer negotiations, utilization management, or network adequacy assessments should focus on Medicare pathways and capacity for SBRT/IMRT services. Any evaluation of access or competitive positioning within Washington, DC should account for this provider’s national outlier status on key radiotherapy codes and its lack of Medicaid claims in the dataset.
