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

Why is the Medicaid comparison limited to Hawaii 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. Hawaii (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 single‑payer in the datasets: total Medicare revenue is $496.3K and there is no Medicaid billing on file, so all billed activity in the available data is concentrated in Medicare. That makes Medicare the sole observable payer for profiling volume, service mix, and competitive standing for this NPI.

Revenue is highly concentrated in a small set of services: the precomputed top 3 Medicare codes (99214, 78452, 93306) account for 49.9% of this provider's total Medicare revenue. Those three codes individually generate $116.8K (23.5%), $65.5K (13.2%), and $65.4K (13.2%) respectively, indicating reliance on a narrow set of office E/M and cardiac imaging procedures for roughly half of Medicare dollars.

The code mix indicates an outpatient cardiology practice with significant noninvasive imaging and nuclear stress testing capacity. High‑revenue E/M code 99214 (1.2K claims, $116.8K revenue) sits alongside imaging codes 93306 (409 claims, $65.4K) and nuclear stress testing 78452 (183 claims, $65.5K), consistent with a practice that pairs clinic visits with on‑site diagnostic imaging and stress studies.

Nuclear cardiology throughput appears material: 78452 generated $65.5K (13.2% of Medicare revenue) and is ranked at the 90th percentile (described as typical, unremarkable volume), while supply/drug lines that support nuclear stress testing — A9500 (362 claims, $34.4K) and J2785 (732 claims, $31.5K) — contribute $34.4K (6.9%) and $31.5K (6.3%) respectively. The presence of both the radiopharmaceutical A9500 and the pharmacologic stress agent J2785 in substantial claim counts supports a steady nuclear stress testing program rather than occasional use.

Echocardiography is a clear service-line strength with both routine and advanced studies represented: 93306 produced $65.4K (13.2%) at a typical national volume ranking, while stress/continuous echo 93351 (147 claims, $28.4K; 5.7%) and advanced speckle‑tracking 93356 (382 claims, $12.2K; 2.5%) are ranked as notably above typical national volume. This pattern suggests the practice provides not only baseline transthoracic echo but also higher‑complexity and exercise/monitoring echo services.

Vascular diagnostics are another substantive area: lower‑extremity duplex 93925 (181 claims, $38.6K; 7.8%) and related vascular duplex codes 93880 ($23.5K, 4.7%) and 93978 ($22.8K, 4.6%) appear in the top earners, with 93925 and 93978 ranked at the 95th and 96th percentiles respectively (93978 described as notably above typical). Together these codes indicate substantial noninvasive arterial/venous testing capacity.

Office visit and E/M mix skews toward higher‑complexity established visits: 99214 is the largest single revenue driver at $116.8K (23.5%) and is an extreme outlier nationally (far above typical national volume), while higher‑level visit 99215 accounts for $13.6K (2.7%) at a typical volume. The extreme outlier status of 99214 suggests heavy clinic throughput or a strong focus on established patient management in the Medicare population.

The provider has long tenure in the registry (NPI enumerated 2006-08-04, ~20 years ago), and competitive standing is mixed: overall Medicare revenue is modest at $496.3K in absolute terms, yet for specific codes the provider ranks well above peers (examples include 99214 as an extreme outlier and several echo and vascular codes described as notably above typical). Because there is no Medicaid billing on file, there is no in‑state Medicaid footprint to compare; assessment of competitive position should therefore focus on Medicare imaging and diagnostic dominance rather than cross‑payer market share.
