Lifetime revenue by payer source (source: CMS Medicare & Medicaid claims data)
| Payer Source | Total Paid |
|---|---|
| Medicare | $337.7K |
| Medicaid | $520 |
This provider is effectively Medicare-centric: total Medicare revenue is $337.7K compared with total Medicaid revenue of $517, so Medicare dominates the revenue mix and Medicaid represents a negligible share of billed dollars. The Medicaid footprint is tiny in scale and unlikely to drive major operational or contract decisions for this provider.
Revenue concentration is high on a few neuroimaging procedures: the top three Medicare codes account for 45.8% of this provider's total Medicare revenue, led by 70450, 70551, and 70553. Those three codes are all brain imaging studies (CT and MRI with/without contrast), indicating that a substantial portion of Medicare income comes from core neuroradiology exams.
The code mix and highest-revenue items point to a specialized neuroradiology service line: 70450 (CT head no contrast), 70551 (MRI brain no contrast), and 70553 (MRI brain with and without contrast) are the primary drivers, and the presence of CTA codes 70496 and 70498 plus multiple spine MRI codes (72141, 72148) indicates capability in both vascular/head and spine diagnostic imaging. This pattern is consistent with a practice structured around advanced diagnostic imaging rather than general radiology or interventional procedures.
On competitive standing, this provider ranks at the very top nationally for some high-revenue Medicare codes: 70450 and 70551 each rank at the 100th percentile and are labeled extreme outliers, and 70553 ranks in the 98th percentile (notably above typical national volume). Multiple additional Medicare codes (for example, 70496, 70498, 72141, 72131) also appear in very high percentiles, suggesting the provider is a nationally high-volume performer for many neuroradiology services.
Medicaid billing is highly concentrated and minimal: the top three Medicaid codes account for 100.0% of Medicaid revenue, with 70450 ($408, 79.5% of Medicaid revenue) and 71045 ($105, 20.5% of Medicaid revenue) comprising the reported claims. State-level ranks for those Medicaid codes are low to modest (70450 ranks #24 of 25, 0th percentile; 71045 ranks #36 of 38, 5th percentile), indicating the provider is not a major Medicaid imaging vendor in-state.
Though focused on neuroradiology, the provider also bills a mix of lower-revenue general imaging on Medicare: chest x‑ray 71046 ($3.2K) and single-view chest 71045 ($2.8K) appear on the list, as do musculoskeletal radiographs such as 73562 ($840). These items are small shares of total Medicare revenue but indicate some broader imaging services are offered alongside high-volume neuroimaging.
The statistical outlier labels in the Medicare file are striking and concentrated in advanced imaging codes: several entries are explicitly marked as "extreme outlier" or "notably above typical national volume." This consistent outlier status across multiple brain and spine imaging codes points to unusually high per-provider volume for diagnostic neuroradiology relative to national peers, rather than an isolated spike on a single code.
The provider has long tenure in the dataset, with NPI enumerated 2005-10-25 (~21 years ago). That sustained enrollment combined with the repeated high national ranks for core neuroradiology CPTs suggests an established imaging practice that has maintained high Medicare imaging volumes over an extended period.
