    Key Findings

    This provider’s Medicare activity is concentrated in high-acuity and office E/M services: 99233 ($221.3K, 29.9% of Medicare revenue), 99214 ($184.6K, 24.9%), and 99232 ($115.9K, 15.6%) together account for 70.4% of total Medicare revenue. The code mix — two subsequent hospital inpatient/observation E/M codes plus a high-complexity established outpatient visit — indicates a practice model that spans hospital-based pulmonary care and substantial outpatient clinic volume focused on ongoing management of established patients.

    Revenue scale is modest but Medicare‑dominated: total Medicare revenue is $740.1K and there is no Medicaid billing on file, so the provider effectively operates as single‑payer (Medicare) in the available claims data. The absence of Medicaid activity means Medicaid-related service-line or payer-negotiation observations cannot be drawn from this profile.

    The provider ranks as a high-volume national outlier on the top three revenue-driving Medicare codes: 99233 is an "extreme outlier" (ranks #219 of 128818), 99214 is also labeled an "extreme outlier" (ranks #1305 of 479517), and 99232 is an "extreme outlier" as well (ranks #1537 of 177383). These rank/percentile signals point to unusually large national volumes for inpatient/subsequent care and mid-level outpatient E/M relative to peers, supporting a characterization of the provider as a major national participant for those specific services.

    Beyond E/M services, the provider shows meaningful sleep and pulmonary function activity: 95810 generated $50.6K (6.8%) and 95811 generated $32.4K (4.4%) of Medicare revenue, while PFT-related codes such as 94729 ($8.2K, 1.1%) and 94726 ($7.7K, 1.0%) are also present. This mix is consistent with a pulmonology practice that incorporates diagnostic sleep testing and pulmonary function labs alongside inpatient and clinic care.

    Remote physiologic monitoring (RPM) is a visible ancillary service line: 99457 ($15.9K, 2.1%), 99454 ($14.3K, 1.9%), and 99458 ($3.5K, 0.5%) together indicate active RPM billing for chronic disease management. The presence of both setup code 99453 (albeit small at $195) and monthly RPM codes suggests the provider leverages connected-device workflows for managing respiratory conditions in the Medicare population.

    Several secondary codes show typical national volumes rather than outlier status: sleep study codes 95810 and 95811 are described as "typical, unremarkable volume" (91st and 72nd percentiles respectively), and many PFT and spirometry codes fall in the 70–90th percentile range. These profile elements imply the provider’s sleep and pulmonary testing operations are within expected ranges for peers and not the primary source of the extreme volume signal seen in the inpatient/office E/M codes.

    Clinical intensity is reflected in higher-level inpatient and outpatient E/M usage rather than low-complexity office visits: lower-level codes such as 99211 and 99213 account for small shares ($2.6K and $5.7K respectively) while high-complexity codes dominate revenue. This suggests the practice’s case mix favors more complex management and inpatient follow-up rather than a large volume of low-acuity office encounters.

    The provider has long tenure on file with an NPI enumerated on 2006-07-20 (~20 years ago), which aligns with the high ranked volumes on several established E/M codes and may reflect an entrenched referral footprint or long-standing hospital privileges supporting the observed inpatient and outpatient activity. Long enumeration combined with concentrated Medicare revenue and no Medicaid billing frames this profile as an experienced, Medicare-focused pulmonary clinician with specialty ancillary services (sleep testing and RPM).
