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

Why is the Medicaid comparison limited to Louisiana 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. Louisiana (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

The provider’s billing mix centers on cardiology diagnostic imaging and high-volume outpatient evaluation and management. The top revenue codes include 78492 (myocardial perfusion PET) with 224 claims generating $246K (23.7% of Medicare revenue), A9555 (rubidium rb-82) with 226 claims generating $91.8K (8.9%), and 93306 (2D transthoracic echo) with 703 claims generating $76.6K (7.4%), indicating an operation that performs advanced nuclear cardiac imaging alongside routine echocardiography and clinic visits. These services align with the Interventional Cardiology Physician taxonomy on the record.

Revenue concentration is high: the precomputed top‑3 Medicare codes account for 52.8% of this provider’s total Medicare revenue. Those three codes are 78492 ($246K, 23.7%), 99214 ($209.3K, 20.2%), and A9555 ($91.8K, 8.9%), showing that just a few imaging and E/M services drive the majority of billed Medicare dollars. This concentration suggests financial sensitivity to utilization changes in those specific service lines.

Payer mix is effectively single‑payer Medicare: total reported Medicare revenue is $1.1M while there is no Medicaid billing on file. The absence of Medicaid revenue means the provider’s public‑payer exposure is concentrated entirely in Medicare reimbursement and utilization patterns. Analysts should treat Medicaid-network position as not reflected in these claims.

Competitive standing varies by code but is extreme for several high-volume services. The office E/M code 99214 appears as an “extreme outlier” (2.4K claims, $209.3K revenue; rank #666 of 479,517, 100th percentile) indicating far higher outpatient E/M volume than typical peers; similarly, 93000 shows 1.8K claims and ranks at the 100th percentile as an “extreme outlier,” and 93880 (duplex arterial scan) ranks in the 99th percentile as an “extreme outlier,” suggesting this provider is a major high‑volume participant nationally for common cardiology diagnostics and outpatient encounters. By contrast, 78492 (rank #99 of 926, 89th percentile) sits at a more typical national volume for myocardial perfusion PET despite being the top revenue driver here.

Several codes are notably above typical volumes, reinforcing a pattern of sustained diagnostic throughput and chronic care management. For example, 99424 is “notably above typical” (1.4K claims, $88.3K; rank #10 of 228, 96th percentile), 93306 is 94th percentile (703 claims, $76.6K), and J2785 is 94th percentile (916 claims, $37.6K), indicating repeated use of pharmacologic stress agents, echo, and monthly complex care management services. These patterns point to a patient panel with substantial chronic cardiovascular morbidity and frequent monitoring requirements.

The code mix includes both noninvasive diagnostics and some interventional activity, indicating access to procedural capability beyond office‑based services. Procedural codes such as 93458 (55 claims, $11.4K) for imaging supervision during coronary angiography and 92928 (11 claims, $5.1K) for single‑vessel stent placement are present alongside high volumes of noninvasive testing (e.g., 93000, 93880). This combination suggests the provider bills for a blend of clinic‑based management, advanced imaging, and occasional catheter‑based interventions.

Financial scale is modest but focused: reported Medicare revenue of $1.1M indicates a mid‑level revenue footprint concentrated in a few high‑volume cardiology services rather than broad multispecialty billing. The heavy reliance on a handful of codes means revenue is efficient for those service lines but also concentrated, which may affect negotiations or vulnerability to coding/utilization shifts for the top revenue drivers. Analysts should interpret market impact relative to code‑level percentiles rather than raw dollars alone.

The provider has a long NPI tenure, enumerated 2005-05-24 (~21 years ago), which indicates an established presence in the Lafayette, LA market. That longevity combined with very high outpatient visit volume for 99214 supports the view of a sustained outpatient panel and persistent service patterns rather than a newly emergent billing profile.
