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

Why is the Medicaid comparison limited to Rhode Island 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. Rhode Island (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 a radiation oncology clinician by taxonomy and the billing mix is dominated by radiation treatment delivery and planning services. The single largest revenue source is G6015 (595 claims, $176.1K revenue, 44.1% of this provider's total Medicare revenue), and other high‑value technical codes such as 77014 (678 claims, $62.4K, 15.6%) and 77301 (35 claims, $51.6K, 12.9%) point to a practice primarily delivering fractionated external beam therapy with IMRT planning and delivery components.

Revenue concentration is pronounced: the precomputed top‑3 codes account for 72.6% of this provider's total Medicare revenue, which indicates most Medicare dollars are tied to a small set of technical radiation codes rather than a broad mix of services. That concentration raises operational sensitivity to changes in utilization or reimbursement for those specific codes (G6015, 77014, 77301).

Payer mix is effectively single‑payer Medicare: lifetime Medicare revenue is $399.1K and there is no Medicaid billing on file. With Medicaid activity absent, analyses of this provider should treat commercial and Medicare dynamics as the primary revenue levers, and not rely on Medicaid as a source of volume or cross‑subsidy.

Competitive standing on the highest‑revenue codes is modest and broadly "typical, unremarkable" nationally rather than dominant. G6015 ranks #660 of 1429 providers (54th percentile; typical, unremarkable volume), 77014 ranks #1436 of 4303 (67th percentile; typical, unremarkable volume), and 77301 ranks #1940 of 3815 (48th percentile; typical, unremarkable volume), indicating routine participation in these services but not market leadership on a national basis.

Operational detail in the code mix supports an active treatment workflow with frequent fraction deliveries and ongoing physics oversight: 77336 (ongoing medical physics consultation) appears with 186 claims and $13K revenue (3.3%), while 77427 (radiation therapy delivery) shows 179 claims and $27.4K (6.9%). The presence of both treatment delivery and weekly physics codes is consistent with a practice managing courses of radiation therapy rather than occasional consults only.

There are low‑percentile footprints in some specialized or advanced service codes that suggest limited use of certain technologies: G6017 (intra‑fraction localization/tracking) has $731 revenue (0.2%) and ranks #321 of 344 providers (6th percentile; typical, unremarkable volume), and 77334 (custom device construction) has $4.2K (1.1%) and ranks at the 12th percentile. These placements indicate selective or infrequent use of intra‑fraction tracking and custom device construction relative to national peers.

Clinical evaluation and management activity is present but secondary to technical radiation services: 99213 accounts for $9.7K (2.4%) with 156 claims and is reported at the 72th percentile (typical, unremarkable volume), 99205 contributes $6.6K (1.7%) at the 69th percentile, and 99215 contributes $3.2K (0.8%) at the 31th percentile. This mix suggests the provider conducts office visits and new patient evaluations alongside a heavier emphasis on treatment delivery codes.

The provider has a long enrollment history, with NPI enumeration on 2005-05-24 (~21 years ago), which supports a stable presence in the Medicare program. Given that tenure but a lifetime Medicare revenue total of $399.1K, the profile is consistent with a smaller, focused radiation oncology practice or a clinician whose Medicare volume is concentrated into a limited set of technical treatment services rather than broad, high-volume outpatient practice expansion.
