    Key Findings

    This profile is clearly emergency-medicine–centered: the top paid services are ED E/M visits (99284 and 99285) and a critical care entry (99291), with the provider recording 245 claims for 99284 ($83 avg paid/claim, $20.3K revenue) and 104 claims for 99285 ($136 avg paid/claim, $14.1K revenue). The code mix (moderate- and high-level ED E/M plus some critical care) is consistent with hands-on emergency department practice rather than outpatient clinic work or procedural specialties.

    Medicare revenue is modest in absolute terms at $41K, and the provider has no Medicaid billing on file; this is effectively a single-payer (Medicare) footprint. The lack of any Medicaid claims — "none below" — means the provider has limited exposure to Medicaid-managed care arrangements and state program flows.

    Revenue concentration is high: the precomputed top-three Medicare codes account for 91.9% of Medicare revenue, driven by 99284 (49.7%), 99285 (34.6%), and 99291 (7.6%). In dollar terms those three codes correspond to $20.3K (99284), $14.1K (99285), and $3.1K (99291), which together dominate this provider’s Medicare book.

    99284 is a national outlier for volume: it ranks #1041 of 64306 providers (98th percentile) and is explicitly described as "notably above typical national volume for this code," indicating unusually high utilization of moderate-level ED visits compared with peers. By contrast, 99285 (rank #30553 of 61347, 50th percentile) and 99291 (rank #58525 of 71290, 16th percentile) are described as "typical, unremarkable volume," so the provider’s competitive strength is concentrated on 99284 rather than across higher-acuity codes.

    Although 99291 is present, the absolute activity is small (19 claims, $164 avg paid/claim, $3.1K revenue) and the national rank is low; the data label for 99291 is "typical, unremarkable volume," which, together with the 16th-percentile rank, signals limited critical-care billing relative to national peer groups. This suggests the provider occasionally delivers time-based critical care but does not have a substantial critical-care billing footprint.

    Payment-per-claim patterns align with acuity: 99291 and 99285 have higher avg paid/claim ($164 and $136 respectively) compared with lower-acuity codes such as 99283 ($46 avg) and ECG interpretation 93010 ($6 avg). These per-claim differences underline that higher-acuity encounters (when billed) materially increase revenue despite lower claim counts.

    Tenure is moderate: the NPI was enumerated on 2017-04-18 (~9 years ago), indicating roughly nine years of enrollment activity to generate the recorded Medicare revenue. That tenure supports interpretation of the observed code mix as an established practice pattern rather than a very recent change in specialty or location.

    From a payer/product strategy viewpoint, the combination of small total Medicare revenue ($41K), near-absence of Medicaid activity, and high concentration in a single ED code (99284) presents both risk and clarity: revenue is heavily dependent on sustained ED visit volume for 99284 (49.7% of Medicare revenue), so shifts in site-of-service patterns or payer mix could disproportionately affect the provider’s Medicare receipts.
