    Key Findings

    This profile is overwhelmingly infusion- and drug-centric: the single largest line-item is J9271 (pembrolizumab) with 17.2K claims and $739.6K revenue (46.9% of the provider's Medicare revenue), supported by J0897 (denosumab) at $219.2K (13.9%) and Q5115 (rituximab-abbs) at $151.6K (9.6%). Those three immunotherapy/biologic injection codes together account for 70.5% of this provider's total Medicare revenue, indicating the practice operates primarily as an oncology infusion service rather than a visit-driven primary care clinic.

    Medicare is the sole payer of scale for this NPI: lifetime Medicare revenue is $1.6M while there is no Medicaid billing on file. This makes the provider effectively single-payer (Medicare) at present, concentrating reimbursement and risk exposure in that program rather than in state Medicaid.

    The provider shows a concentrated revenue base driven by high-cost injectable therapies rather than E&M services: office visit code 99214 generated $91.4K (1K claims, $88 avg) and 99213 generated $32.1K (563 claims, $57 avg), both substantially smaller than the pembrolizumab line. This mix implies clinical capacity and revenue depend primarily on drug administration and infusion throughput instead of routine outpatient evaluation and management.

    Competitive standing by code is mixed: J9271 (pembrolizumab) is a typical, unremarkable volume position nationally (ranks #541 of 1841; 70th percentile), while J0897 (denosumab) ranks #812 of 10057 (92th percentile; typical, unremarkable volume) and Q5115 (rituximab-abbs) is relatively concentrated versus peers (ranks #11 of 79; 87th percentile; typical, unremarkable volume). At the same time, several administration codes are extreme outliers versus national peers — for example 96413 (chemotherapy infusion) is an extreme outlier at the 99th percentile (ranks #44 of 7514) — signaling above-typical chemotherapy administration intensity compared with national peers.

    Multiple infusion- and administration-related codes are flagged as unusually high-volume relative to peers: 96375 is a 99th percentile extreme outlier (ranks #35 of 5191), J2469 is a 100th percentile extreme outlier (ranks #7 of 2634), and J9201 is a 100th percentile extreme outlier (ranks #4 of 631). These statistical flags, together with the high share of revenue from drug codes, suggest operational emphasis on repeated infusion sessions and a practice workflow optimized for injectable oncology therapies.

    The provider has long tenure: the NPI was enumerated 2006-08-30 (~20 years ago), indicating an established practice presence in HATTIESBURG, MS. That longevity plus the infusion-heavy code mix may reflect a stable, specialized service line focused on oncology medications and supportive infusions rather than recent or transient activity.

    There are large disparities between claim counts and per-claim payments for some items that affect revenue composition: J1439 shows 55.5K claims at $1 avg paid/claim for $55.5K revenue, and J2469 shows 5.5K claims at $1 avg paid/claim for $5.5K revenue. These patterns indicate very high claim volume for low-dollar items while most dollars are concentrated in a few high-cost biologic injections, which has implications for utilization monitoring and operational throughput metrics.
