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.

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 single-payer Medicare operator: total Medicare revenue is $1.2M while Medicaid revenue is none, indicating no Medicaid billing on file. The NPI was enumerated 2006-10-09 (~20 years ago), consistent with an established solo or small-group practice in DEDEDO, GU.

The clinical/service mix is concentrated in vascular and interventional radiology with a clear operational focus on dialysis-access interventions and endovascular work. High-revenue CPTs such as 36902 (dialysis circuit angiography with angioplasty), 36906 (thrombectomy with stent placement), and 36903 (stent placement for dialysis circuit) show the practice spends most of its time on complex dialysis access procedures and image-guided endovascular therapies.

Revenue is highly concentrated: the precomputed top-3 Medicare codes account for 65.3% of the provider’s total Medicare revenue. Individually those top codes include 37225 ($288.5K revenue, 24.1% of this provider's total Medicare revenue), 37229 ($257.5K revenue, 21.5% of this provider's total Medicare revenue), and 36902 ($234.8K revenue, 19.6% of this provider's total Medicare revenue), demonstrating reliance on a small set of high-reimbursement interventions.

Competitive standing is mixed by code: the provider ranks strongly on dialysis angioplasty and imaging procedures (36902 ranks #134 of 1666 providers nationally, 92th percentile), indicating above-typical national volume for that core service. By contrast, 37229 (rank #258 of 603, 56th percentile) and several other codes sit at typical national volumes, which suggests the provider is a notable specialist in certain procedures but otherwise a modest participant among peers.

There is a pronounced procedural outlier in use of ultrasound guidance: 76937 appears as an extreme outlier with 478 claims and a national rank of #7 of 12234 providers (100th percentile), described in the source as "extreme outlier, far above typical national volume." This suggests the practice relies heavily on ultrasound-assisted vascular access and guidance relative to peers and may use ultrasound systematically across many cases.

Practice throughput includes substantial procedure-support and monitoring activity: 99152 (initial monitored sedation) shows 139 claims and 99214 (established patient E/M) has 130 claims, indicating frequent use of monitored sedation and a meaningful outpatient clinic or follow-up visit volume tied to procedural care. These supporting services align with an interventional practice that performs time-intensive, image-guided procedures.

Several radiology supervision and interpretation codes (e.g., 75625 at a notably above-typical national volume, and 75710/75774 showing typical to above-typical volumes) indicate the provider performs or supervises a range of angiographic imaging studies beyond dialysis-specific work. This mix reinforces a service-line that combines diagnostic angiography with therapeutic dialysis access interventions.

Business risk and referral dependence: given that a small set of high-revenue interventional codes drive the majority of Medicare income, the provider’s revenue is sensitive to changes in dialysis-referral patterns, outpatient dialysis volumes, or reimbursement for those specific CPTs. The absence of Medicaid billing also means revenue diversification across payers is limited, which could affect contract negotiations or exposure to payer-specific policy changes.
