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

Why is the Medicaid comparison limited to Delaware 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. Delaware (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’s Medicare business is concentrated in advanced cross-sectional and screening imaging: the top three revenue codes are 72197 (400 claims, $114K revenue, 17.7%), 74183 (365 claims, $97.8K revenue, 15.2%), and 71271 (423 claims, $58.4K revenue, 9.1%). Those three codes alone account for 41.9% of the provider’s total Medicare revenue, indicating operations oriented toward high-volume MRI and low-dose CT screening workflows rather than a broad mix of general radiology visits.

Revenue scale and payer mix are highly imbalanced: total Medicare revenue is $735.4K while there is no Medicaid billing on file. This makes the provider effectively Medicare-only on the public-payer side, concentrating reimbursement exposure to the Medicare population and limiting diversification into state Medicaid revenue streams.

Competitive standing on several high-value codes is unusually strong nationally: 72197 ranks #41 of 4732 providers (99th percentile; extreme outlier, far above typical national volume for this code) and 74183 ranks #66 of 7242 providers (99th percentile; extreme outlier). 71271 ranks #26 of 8424 providers (100th percentile; extreme outlier), signaling national-level dominance in pelvic MRI, abdominal MRI, and lung LDCT screening volumes relative to peers.

Beyond the top three, the provider shows multiple above-typical volumes across CT and ultrasound services that extend the service footprint: 71250 (350 claims, $37.8K revenue) ranks in the 96th percentile and is described as notably above typical national volume, and 76377 (302 claims, $19.9K revenue) ranks in the 98th percentile and is notably above typical national volume for advanced image postprocessing. These higher-percentile codes imply the practice runs substantial throughput for CT studies and performs 3D postprocessing work, supporting a full-service imaging center model.

Service-line breadth includes screening mammography, diagnostic ultrasound, and vascular imaging in addition to CT/MRI: 77067 (215 claims, $32K revenue) and 77063 (218 claims, $13.1K revenue) appear at roughly median national volumes, while ultrasound codes such as 76700 (200 claims, $17.8K revenue) and duplex/vascular codes 93971/93970 are in the higher percentiles (97th and 71st/89th percentiles respectively). This mix suggests the provider handles both routine screening (mammography, LDCT screening) and higher-complexity diagnostic imaging (cross-sectional MRI/CT and vascular duplex).

The provider’s claim volumes underscore operational scale in specific modalities: several codes report high claim counts (e.g., 423 claims for 71271, 400 claims for 72197, 365 claims for 74183, 546 claims for 71046), which, coupled with high national ranks for key codes, indicates a referral or centralized-imaging role rather than a low-volume clinic. High claim counts on low-paid-per-claim services (e.g., 71046 with 546 claims at $28 avg paid/claim) also point to a balanced throughput model mixing high-volume low-acuity studies with higher-reimbursement cross-sectional imaging.

Concentration of revenue in a few codes presents both a market advantage and operational risk: dominance in MRI pelvis, MRI abdomen, and LDCT screening provides a defendable niche and likely steady referral flow, but the fact that 41.9% of Medicare revenue is tied to the top three codes increases sensitivity to reimbursement or utilization changes that affect those specific services. Absent Medicaid revenue, any shifts in Medicare policy for these codes would disproportionately affect the provider’s public-payer revenue base.

The provider has an established enrollment history, having been enumerated on 2006-10-25 (~20 years ago), which supports interpretation of these volumes as the output of a mature practice. Longevity plus the observed high national percentiles for several imaging codes suggests an entrenched operational capability in advanced imaging services rather than a transient billing pattern.
