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.

This provider’s billing is effectively single‑payer: total Medicare revenue is $338.9K and there is no Medicaid billing on file, so the practice’s Medicare activity drives virtually all recorded public‑payer revenue. The top three Medicare codes (78492, A9555, 93306) together account for 50.3% of Medicare revenue, underscoring dependence on a small set of imaging and echo services.

The top revenue drivers point to an imaging‑focused cardiovascular practice: 78492 ($76.6K, 22.7%) is myocardial perfusion PET imaging, A9555 ($49K, 14.5%) is rubidium rb‑82 per study dose, and 93306 ($44.2K, 13.1%) is transthoracic echocardiography. This mix indicates the provider performs advanced nuclear perfusion imaging alongside high volumes of standard echocardiography and tied tracer administration rather than being predominantly a procedural interventionalist.

Revenue concentration is notable: the precomputed top‑3 share is 50.3%, with the single largest code 78492 representing $76.6K (22.7%) of total Medicare revenue. That concentration implies that reimbursement changes, shifts in referral patterns, or equipment availability for myocardial perfusion PET/ rubidium studies could materially affect overall Medicare revenue.

Competitive standing vs. national Medicare peers is mixed across services. 78492 ranks #478 of 926 (47th percentile; typical, unremarkable volume for this code) and A9555 ranks #638 of 1266 (49th percentile; typical, unremarkable volume for this code), indicating modest national activity for PET studies and rubidium use, while 93306 ranks #3534 of 24624 (86th percentile; typical, unremarkable volume for this code), showing relatively strong transthoracic echo volume versus peers.

Outpatient evaluation-and-management and routine cardiac testing are substantial parts of volume: 99213 appears 447 claims ($35.8K, 10.6% of Medicare revenue) and ranks #32770 of 457151 (93th percentile; typical, unremarkable volume for this code), and 93010 (ECG interpretation) has 843 claims ($6.7K, 2.0%) and ranks #4513 of 50616 (91th percentile; typical, unremarkable volume for this code). These figures indicate steady clinic follow‑up and high ECG throughput in addition to imaging services.

The provider also maintains inpatient/observation activity: 99232 (167 claims, $13.7K, 4.1%) and 99233 (111 claims, $13.4K, 4.0%) are present in the mix, and 99223 (49 claims, $8.7K, 2.6%) and 99222 (36 claims, $4.3K, 1.3%) reflect both initial and subsequent hospital evaluation‑and‑management work. That spread between office visits, inpatient consults, and imaging suggests a blended clinic-plus‑hospital role rather than a pure outpatient imaging center.

There are low‑volume items relative to national peers that suggest limited provision of some advanced imaging or contrast‑driven services: 70498 ranks #11478 of 12442 (5th percentile; typical, unremarkable volume for this code), 93454 ranks #2071 of 2695 (18th percentile; typical, unremarkable volume for this code), and Q9957 ranks #835 of 1074 (17th percentile; typical, unremarkable volume for this code). Those low percentiles, together with stronger echo and routine ECG percentiles, point to a practice concentrated on noninvasive cardiac imaging and diagnostics rather than broader radiology or interventional imaging services.

The provider’s NPI was enumerated 2006-07-13 (~20 years ago), indicating long tenure in the Medicare program. That level of tenure combined with the coding mix implies an established cardiovascular imaging practice with a consistent, Medicare‑centered referral base rather than a newly established operator.
