Lifetime revenue by payer source (source: CMS Medicare & Medicaid claims data)
| Payer Source | Total Paid |
|---|---|
| Medicare | $283.6K |
| Medicaid | $1K |
This provider’s billing is overwhelmingly Medicare-driven: total Medicare revenue is $283.6K versus total Medicaid revenue of $1K, so the practice is effectively single-payer in scale with Medicare accounting for the vast majority of billed services. Medicaid activity is trace in dollar terms and concentrated in low-acuity chest radiography.
Revenue concentration on Medicare is high and narrowly focused: the precomputed top 3 Medicare codes account for 45.5% of this provider’s total Medicare revenue, led by 74177 ($48.2K, 18.0%), 70450 ($45.6K, 17.0%), and 72125 ($28.3K, 10.6%). These three CT-focused codes drive nearly half of the Medicare intake, indicating concentrated dependence on a few cross-sectional imaging services.
The code mix indicates a CT- and CTA-centric diagnostic radiology operation: high-revenue codes include CT abdomen/pelvis with contrast (74177), CT head without contrast (70450), CT cervical spine without contrast (72125), and several CTA/contrast neck and chest codes (71275, 70496, 70498). This pattern is consistent with a practice performing high volumes of advanced cross-sectional and vascular imaging rather than primarily plain-film or MRI services.
On competitive standing for Medicare, this provider is a national high-volume outlier for multiple CT services: 72125 ranks #6 of 17442 providers (100th percentile; extreme outlier), 70450 ranks #84 of 21092 (100th percentile; extreme outlier), and 74177 ranks #179 of 23621 (99th percentile; extreme outlier). Those ranks indicate this clinician performs these CT exams at volumes far above typical national peers.
Medicaid activity is minimal and limited to basic chest X-rays: the top Medicaid codes are 71046 ($756, 79.5% of Medicaid revenue) and 71045 ($195, 20.5% of Medicaid revenue), which together represent the precomputed top-3 share of 100.0% of Medicaid revenue. In-state ranks for those chest X-ray codes are modest (71046: #86 of 131, 35th percentile; 71045: #57 of 77, 26th percentile), signaling a modest Medicaid footprint with no statewide dominance.
There is a pronounced payer-service split: Medicare utilization is concentrated in higher-acuity CT and CTA exams that generate the bulk of revenue, while Medicaid billing is confined to low-reimbursement chest radiographs. This divergence suggests the provider’s clinical activity and revenue generation is anchored in Medicare patients requiring advanced imaging rather than routine radiography billed to Medicaid.
Several non-top-3 Medicare codes further support a vascular/CTA and advanced CT profile: 71275 ($25.1K, 9.4%), 70496 ($22K, 8.2%), and 70498 ($21.3K, 7.9%) each rank in high national percentiles (99th) and are flagged as extreme outliers or notably above typical national volume. The presence of multiple high-ranking CTA and contrast-enhanced CT codes reinforces that the practice performs substantial vascular imaging in addition to standard CT studies.
Provider tenure is established: the NPI was enumerated on 2014-06-16 (~12 years ago), giving a multi-year billing history that aligns with the high national ranks on CT work. Combined with the concentrated revenue mix and consistent outlier ranks, the pattern points to a stable, established diagnostic radiology practice with a clear operational emphasis on CT/CTA services.
