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 District of Columbia for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to District of Columbia 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. District of Columbia (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 bills almost exclusively to Medicare with Total Medicare revenue of $331.5K and no Medicaid billing on file, making its public payer footprint effectively single-payer. The top three Medicare codes (99215, 78452, 93306) account for 77.6% of the provider's Medicare revenue, indicating a tightly concentrated revenue base around a few services.

Revenue concentration is heavily skewed toward three codes: 99215 generated $120.5K (36.4% of Medicare revenue) across 825 claims at $146 avg paid/claim, 78452 generated $71.4K (21.5%) across 172 claims at $415 avg paid/claim, and 93306 generated $65.1K (19.7%) across 462 claims at $141 avg paid/claim. Because these three codes together make up 77.6% of Medicare receipts, reimbursement changes or utilization shifts for these services would materially affect this provider's revenue.

The mix of high-level office E/M visits (99215), nuclear cardiology / SPECT imaging (78452 and A9500), and transthoracic echocardiography (93306 and 93351) suggests an outpatient cardiology practice with a strong diagnostic-imaging emphasis. Presence of procedure codes such as J2785 (regadenoson injections), A9500 (technetium tc-99m sestamibi), and stress testing code 93015 supports an on-site imaging or stress-lab capability rather than a pure consult-only practice.

99215 performance is a clear national outlier: the provider ranks #485 of 145531 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code), which indicates an unusually high volume of high-complexity office visits relative to peers. By contrast, 78452 ranks #1727 of 14946 (88th percentile) and 93306 ranks #4267 of 24624 (83th percentile), both characterized in the file as typical, unremarkable volume for those codes, implying strong but not dominant national standing in imaging.

The provider’s billing profile includes inpatient/observation E/M codes (for example, 99233 with 90 claims and $9.3K revenue, 99223 with 59 claims and $8.9K revenue, and 99222 with 15 claims and $1.7K revenue), indicating that hospital-based follow-up and initial inpatient evaluations are part of the service mix. These hospital E/M services are smaller contributors to total Medicare revenue compared with outpatient imaging and high-level office visits but demonstrate a hybrid outpatient/inpatient practice footprint.

Operationally, high claim counts for office E/M and basic cardiac testing point to sustained outpatient throughput: 99215 has 825 claims and 93010 (ECG interpretation) has 631 claims, while imaging claims such as 93306 total 462. This combination of high-volume E/M and diagnostic testing supports a practice model that pairs frequent longitudinal outpatient care with on-site diagnostic services, which has implications for staffing, equipment needs, and capital planning.

Tenure data show the provider's NPI was enumerated on 2005-09-21 (~21 years ago), indicating a long-standing presence in the market; this longevity can factor into network contracting and credentialing considerations. Long tenure paired with the concentrated Medicare revenue mix suggests established referral patterns focused on the specific set of cardiology services that dominate billing.

Because 77.6% of Medicare revenue is concentrated in three codes, payers and financial analysts should flag this provider for sensitivity to reimbursement policy or utilization management changes affecting 99215, 78452, or 93306. The profile does not indicate Medicaid participation, so any shifts in Medicare policy would not be offset by Medicaid volume for this provider.
