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

WESTPAC HEMATOLOGY & ONCOLOGY CENTER INC reports no Medicare billing on file and $456.4K in lifetime Medicaid revenue, making its public payer footprint effectively single-payer (Medicaid) based on available claims data. This concentration of reported revenue into Medicaid should be treated as the dominant commercial data source for payer/provider analysis.

Revenue is highly concentrated in a very small set of procedures: the precomputed top three Medicaid codes (99213, 96413, 99214) account for 92.4% of the provider's Medicaid revenue. Specifically, 99213 drives $287.1K (62.9%), 96413 accounts for $108.4K (23.7%), and 99214 contributes $26.1K (5.7%), indicating a narrow service mix that generates almost all billed Medicaid dollars.

The code mix signals an outpatient oncology practice that couples office evaluation-and-management visits with chemotherapy administration. High volume for 99213 (4.1K claims) alongside 96413 (1K claims) and supporting infusion codes (96375, 96415, 96417) is consistent with routine follow-up E/M visits and IV chemotherapy delivery as the clinic's primary service lines.

96413 (chemotherapy administration) is ranked #1 of 2 providers in-state (100th percentile) for in-state volume; the dataset also characterizes that level as "typical, unremarkable volume." This suggests the practice is the leading reported chemotherapy administrator among a very small peer set in the state, but the peer population for this code is limited, so the market leadership claim should be interpreted in the context of few reporting peers.

99213 (office E/M) ranks #12 of 48 providers in-state (77th percentile) and is also labeled in the data as "typical, unremarkable volume," indicating a moderate-to-strong position among Guam providers for routine established-patient visits without implying regional dominance. By contrast, 99214 (higher-complexity E/M) ranks #23 of 35 (35th percentile), which places the provider below median for more complex established-patient evaluations relative to state peers.

Ancillary and infusion-support codes contribute small amounts of revenue but reflect operational capabilities necessary for an oncology clinic: 96375 totals $11.4K (2.5% of Medicaid revenue) across 437 claims, 96415 adds $6K (1.3%), and several medication/injection lines such as J3315 and J2405 appear at low-dollar volumes. These items support the chemotherapy/E/M mix and indicate on-site medication administration and infusion services, though they are not major revenue drivers.

The provider's NPI was enumerated on 2018-09-19 (~8 years ago), indicating multiple years of reporting history in the state-level dataset. Combined with $456.4K in lifetime Medicaid revenue, the data portray a small, established outpatient oncology practice with steady, localized activity rather than a large-volume regional center.

Operationally, the heavy dependence on two primary codes (99213 and 96413) that together constitute the majority of billed Medicaid revenue creates concentration risk: changes in Medicaid reimbursement or utilization patterns for outpatient E/M visits or chemotherapy administration could have outsized effects on total revenue. Analysts should prioritize monitoring these specific codes when modeling reimbursement sensitivity or assessing contracting leverage.
