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

Why is the Medicaid comparison limited to Alaska 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. Alaska (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’s billing footprint is effectively single‑payer: lifetime Medicare revenue is $363.8K and there is no Medicaid billing on file, indicating negligible Medicaid exposure and that payer mix is highly concentrated on Medicare patients. Analysts should treat Medicaid strategies or state program impacts as irrelevant for this NPI given the absence of any Medicaid claims.

Revenue is heavily concentrated in a small set of services — the top three Medicare codes (99214, 93306, 78452) account for 55.1% of the provider’s total Medicare revenue. The single largest line is 99214 (703 claims, $114 avg paid/claim, $80.1K revenue; 22.2% of Medicare revenue), followed by 93306 (400 claims, $154 avg paid/claim, $61.6K revenue; 17.0%) and 78452 (143 claims, $403 avg paid/claim, $57.6K revenue; 15.9%).

The code mix points to an ambulatory cardiology practice that combines high-volume cognitive visits with in-office diagnostic imaging and stress testing. High counts for office E/M codes such as 99214 and significant revenue from imaging codes 93306 (echocardiography) and 78452 (SPECT myocardial perfusion) plus related supplies and agents (A9500, J2785) imply a clinic workflow built around outpatient cardiac evaluation and nuclear stress protocols.

On competitive standing, this provider is above typical national volume for core office visit codes: 99214 ranks #25973 of 479517 providers nationally (95th percentile; notably above typical national volume for this code) and 99204 ranks #6738 of 227068 providers nationally (97th percentile; notably above typical national volume for this code), signaling a comparatively strong throughput of new and established outpatient visits. By contrast, imaging and procedure codes generally sit in mid‑to‑high percentiles (for example 93306 ranks #5704 of 24624, 77th percentile; 78452 ranks #2395 of 14946, 84th percentile), which describes a competent but not dominant national position for those technical services.

Operationally, the provider’s procedure mix (notably 78452, 93306, 75574, A9500, J2785) indicates reliance on nuclear and advanced cardiac imaging reimbursement streams as key revenue drivers; the presence of CT coronary angiography (75574) and calcium scoring (75571) suggests investment in imaging capability beyond basic echo and ECG services. This has implications for capital, staffing, and supply costs tied to imaging throughput and pharmacologic stress agents.

Tenure data show the NPI was enumerated 2008-08-14 (~18 years ago), indicating a long-established billing record. That longevity combined with concentrated Medicare revenue suggests a stable, Medicare-focused practice rather than a recently established entrant or a Medicaid‑oriented clinic.

From a payer-contracting and risk perspective, the absence of Medicaid billing on file reduces exposure to state program rate variability but concentrates reimbursement risk in Medicare policy and fee schedule changes; with total Medicare revenue of $363.8K, the provider is modest in scale and could be sensitive to shifts in utilization of its top codes that together represent a majority of revenue.
