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

Why is the Medicaid comparison limited to Vermont 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. Vermont (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 public programs: Total Medicare revenue is $175.6K while there is no Medicaid billing on file, indicating the practice’s Medicare activity is the only documented public-payer revenue stream and Medicaid does not appear in the billing footprint. This concentration will make Medicare reimbursement trends and policy changes particularly impactful for the provider’s public-payer cash flow.

Revenue concentration is high: the precomputed top 3 Medicare codes (99215, 99214, 78452) account for 45.5% of this provider’s total Medicare revenue. Those three codes individually generated $27.8K (99215), $26.6K (99214), and $25.6K (78452), so a small set of high-value office visits and a nuclear cardiology study drive nearly half of Medicare receipts.

The code mix points to a clinic-oriented cardiology practice that also performs diagnostic imaging: high-level E/M codes (99215, 99214) dominate visit revenue, while cardiac imaging and testing codes (78452 SPECT, 93306 echo, 93000 ECGs, 93015 stress testing) supply substantial ancillary revenue. The presence of both evaluation/management and imaging codes suggests a service model combining ambulatory cardiology visits with on-site diagnostic testing rather than a pure inpatient or procedure-only practice.

Competitive standing is mixed across service lines: 99215 ranks #9520 of 145531 (93th percentile) and 99214 ranks #87279 of 479517 (82th percentile) even while both are labeled "typical, unremarkable volume" in the source, indicating relatively strong national positioning for high-level office visits by rank but not an extreme outlier in claim patterns. By contrast, advanced diagnostic/interventional codes show more modest national footprints — 93306 is at the 39th percentile (rank #14869 of 24624), 92928 is at the 31th percentile (rank #3376 of 5112), and 93458 is at the 32th percentile (rank #5257 of 7990) — consistent with a practice that leans on outpatient visits and testing rather than high-volume interventional cardiology.

Certain utilization signals stand out by claim counts: 93000 has 596 claims and is described as "notably above typical national volume" at the 94th percentile (rank #4006 of 71016), and office visit volumes are substantial with 99214 at 337 claims and 99215 at 228 claims. These counts indicate high throughput of routine ECG interpretation and frequent high‑level outpatient visits, which likely support recurring diagnostic workflows and steady scheduling demand.

The interventional/cath footprint appears limited in scale: 92928 (coronary stent) shows just 20 claims and $7.6K revenue and ranks in the 31th percentile, while 93458 (imaging supervision for coronary angiography) shows 26 claims and $3.9K revenue at the 32th percentile. Those counts and percentiles point to occasional procedural activity rather than a primary focus on high-volume invasive cardiology.

Absence of Medicaid billing is material for payer strategy: with no Medicaid claims on file, the provider will not be capturing revenue from that state payer pool, which has implications for network negotiations, access for Medicaid beneficiaries, and any analyses comparing in‑state payer mix. Analysts should treat this profile as Medicare-centric when benchmarking utilization, contracting, or population coverage.

The provider is long‑tenured in Medicare: NPI was enumerated on 2006-07-24 (~20 years ago), which suggests an established practice history and a durable presence in the market. Tenure combined with the observed code mix (sustained E/M and diagnostic testing volumes) may reflect a stable outpatient cardiology operation rather than a newly established or transient billing pattern.
