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

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

Key Findings

GUAM SURGICENTER, LLC is effectively a single-payer Medicare provider: Total Medicare revenue is $249.5K and there is no Medicaid billing on file. This means payer mix is highly concentrated on Medicare receipts for the billing captured in the dataset. The provider’s NPI was enumerated on 2010-02-03 (~16 years ago), indicating it has been active for an extended period despite a modest Medicare revenue base.

Revenue concentration is high: the precomputed top 3 Medicare codes by revenue account for 79.4% of this provider's total Medicare revenue. The single largest contributor is G6015 at $141.7K (56.7% of Medicare revenue), followed by G6002 at $34.3K (13.7%), and 77301 at $22.2K (8.9%). This concentration signals that a small set of procedures drive the bulk of reported Medicare income.

The code mix points to an outpatient radiation oncology treatment center focused on image-guided and intensity-modulated external beam therapy. G6015 (intensity modulated treatment delivery) and G6002 (stereoscopic x-ray guidance for localization) together dominate billing, and 77301 (IMRT planning) appears as the third-largest revenue source, consistent with an IMRT-centered service line. The presence of planning and physics codes alongside fraction codes supports a comprehensive radiation therapy workflow rather than isolated consult-only activity.

Competitive standing is mixed across specific services: G6015 ranks #760 of 1429 (47th percentile; typical, unremarkable volume) indicating a modest national footprint for IMRT delivery, while G6002 ranks #354 of 2280 (84th percentile; typical, unremarkable volume) suggesting comparatively stronger use of stereoscopic x-ray localization versus peers. By contrast, 77301 ranks #3440 of 3815 (8th percentile; typical, unremarkable volume), indicating low reported national volume for that planning code despite its share of this provider’s revenue.

Claim and payment patterns underscore how revenue is concentrated by service type: the provider reported 482 claims for G6015 with $294 avg paid/claim, 572 claims for G6002 with $60 avg paid/claim, and only 15 claims for 77301 with $1477 avg paid/claim. The high average payment for 77301 combined with a small claim count suggests that a few planning instances yield outsized payments, while routine fraction delivery and image-guidance account for most day-to-day throughput.

Routine therapy and support codes appear throughout the top lines, consistent with a functioning treatment center rather than a narrow specialty clinic: 77427 (153 claims, $22K revenue, 8.8% of Medicare revenue) and 77336 (115 claims, $7.9K revenue, 3.2%) show ongoing fraction and physics services. These codes rank near median or below-median national percentiles (for example, 77427 at the 50th percentile and 77336 at the 33rd percentile), which aligns with a typical, locally focused operation rather than a high-volume regional hub.

Operational and reimbursement sensitivity is notable because a single code, G6015, accounts for 56.7% of Medicare revenue ($141.7K). Given the absence of Medicaid billing on file, any shifts in Medicare utilization or reimbursement for IMRT delivery would materially affect the practice’s reported revenue. This concentration suggests limited payer diversification in the reported dataset and potential exposure to changes in Medicare coverage or coding.

The provider’s long tenure (NPI enumerated 2010-02-03, ~16 years) combined with a modest lifetime Medicare revenue of $249.5K suggests an established but small-scale outpatient radiation service in Guam. The mix and ranks of billed codes indicate standard radiation oncology services delivered at modest volume, with particular reliance on IMRT delivery and image-guided localization as the primary revenue drivers.
