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 profile is effectively single‑payer: Total Medicare revenue is $387.8K and there is no Medicaid billing on file, so all reported public‑payer activity in the dataset is Medicare only. That concentration means analyses of this provider’s volumes and risk should be framed around Medicare rules and beneficiary mix rather than dual‑payer dynamics.

Revenue concentration is high within a few outpatient/diagnostic codes: the top 3 Medicare codes by revenue (93306, 99214, 99215) account for 40.4% of this provider’s total Medicare revenue. Those three codes individually generate $54.2K (93306), $50.7K (99214), and $44.7K (99215), so a large share of earnings depends on transthoracic echocardiography and higher‑level office E/M visits.

The code mix indicates an outpatient cardiology practice oriented toward diagnostic imaging and higher‑complexity clinic visits rather than high-volume interventional procedures. High‑revenue entries include 93306 (complete transthoracic echo), 78452 (multi‑phase SPECT, $37.3K), and multiple vascular duplex codes (e.g., 93880, 93924), while typical interventional/invasive codes such as 92928 (stent placement, $12.3K) and 93460 (coronary angiography, $9.6K) contribute smaller shares.

Clinical intensity in office visits skews above peers: 99215 ranks at the 95th percentile nationally and is labeled notably above typical national volume, signaling relatively greater use of high‑complexity established patient E/M visits compared with other providers. By contrast, 99214 ranks at the 88th percentile (typical) and 93306 ranks at the 76th percentile (typical), which together suggest higher‑acuity clinic practice but echo volumes closer to peer norms.

Procedural/interventional volume appears modest relative to diagnostic and E/M services: 92928 (percutaneous coronary intervention) ranks at the 37th percentile nationally and accounts for $12.3K (3.3%) of Medicare revenue, indicating that therapeutic PCI is not a primary revenue driver for this NPI. Imaging supervision codes tied to catheterization (93458) provide some procedural revenue ($13.3K, 3.6%) but overall procedural contribution is limited compared with diagnostic testing and clinic visits.

The provider performs a mix of diagnostic cardiac testing that complements clinic care: nuclear SPECT (78452, $37.3K, 10.1%), technetium radiopharmaceuticals (A9500, $17.3K, 4.7%), pharmacologic stress agent J2785 (regadenoson, $13.3K, 3.6%), and exercise/interpretive tests (93015, $6.8K). This pattern supports a service line combining in‑office evaluation with on‑site stress testing and nuclear imaging rather than a pure procedural cath lab model.

Operational and payer‑risk implications follow from the concentration in outpatient E/M and diagnostic codes: because the top revenue drivers are 93306, 99214, and 99215 (combined 40.4%), changes to outpatient E/M valuation or reductions in echo/stress testing utilization would disproportionately affect revenue. Coupled with the lack of Medicaid billing, reimbursement shifts within Medicare or changes in referral sources could materially change the practice’s financial profile.

The provider has an established enrollment history (NPI enumerated 2006‑10‑16, ~20 years ago), which indicates a long tenure in the Medicare system and supports trend analyses over time; however, current measured activity is moderate in scale ($387.8K lifetime Medicare revenue) and concentrated in a narrow set of outpatient diagnostic and E/M services.
