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

Why is the Medicaid comparison limited to Virginia 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. Virginia (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 practitioner is a Nuclear Medicine Physician with long tenure in the Medicare program, having an NPI enumerated on 2010-02-03 (~16 years ago), which indicates an established billing presence and multi-year participation in fee-for-service imaging workflows. The longevity supports experience in high-complexity nuclear imaging services and suggests sustained referral relationships or a stable clinical operation over time.

Medicare dominates this provider’s payer mix: lifetime Medicare revenue is $2.6M while there is no Medicaid billing on file, so this entity is effectively single-payer (Medicare) in the available claims record. Analysts should treat any Medicaid-focused market assumptions as unsupported for this provider because there is no Medicaid activity recorded.

Revenue concentration is high: the precomputed top 3 Medicare codes account for 74.2% of total Medicare revenue, indicating the practice’s income is heavily dependent on a small set of PET/radiopharmaceutical services. This concentration suggests the operation is specialized around advanced PET imaging and related radiotracer administration rather than a broad mix of general nuclear medicine procedures.

Service-line implications from the top codes show a focus on PET/CT and advanced diagnostic radiopharmaceuticals. The leading code 78815 and related codes 78816/78814 describe PET with CT fusion imaging, while A9595, A9584, A9596 and A9587 are proprietary radiotracers (e.g., piflufolastat f-18, iodone-123 ioflupane, gallium ga-68 agents) — collectively this mix indicates the practice performs both high-volume FDG/diagnostic PET-CT studies and specialized molecular PET studies used for oncology and neurologic applications.

Competitive standing on key Medicare products is outsized for certain codes: 78815 is listed as an extreme outlier (ranks #78 of 6566, 99th percentile) and A9552 likewise is an extreme outlier (ranks #28 of 2411, 99th percentile), meaning this provider delivers far more of those services than typical peers nationally and functions as a major volume center for those specific modalities. A9595 is also notably above typical national volume (ranks #32 of 528, 94th percentile), reinforcing a market position strong in PET radiotracer-based diagnostics.

Other codes show typical or modest national participation: A9584 (rank #18 of 149, 89th percentile), 78608 (rank #23 of 301, 92nd percentile), and 78816 (rank #324 of 1983, 84th percentile) reflect solid but not extreme volumes relative to their respective peer groups, indicating the provider mixes some routinely performed nuclear studies alongside the high-volume PET/CT work.

Payer and procedure-level risk/attention points for analysts include the reliance on proprietary radiopharmaceuticals: A9595 (piflufolastat f-18) alone accounts for $642.2K and 24.6% of Medicare revenue, and multiple radiotracer codes appear in the top line items. Contracting, supply chain (radiotracer sourcing), and reimbursement trends for these agents will materially affect revenue and operational capacity.

Operational footprint implication: high average paid/claim amounts for several top codes (for example A9584 avg paid/claim $2056, 78815 avg paid/claim $1489, and 78816 avg paid/claim $1498) combined with concentrated volumes imply capital- and resource-intensive imaging workflows (PET/CT scanners, radiopharmacy access, and specialized staff). Payer negotiations and utilization management for these expensive imaging studies are likely to be key levers for payers and the provider alike.
