Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Missouri for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Missouri only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Missouri (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

Key Findings

This provider is a rheumatology physician based in SAINT LOUIS, MO with long-established Medicare enrollment; the NPI was enumerated on 2005-10-24 (~21 years ago), indicating over two decades of participation in the Medicare program and a sustained billing history. That tenure supports interpretation of billing patterns as representative of an ongoing outpatient infusion/biologic practice rather than a short-term or transient billing spike.

Medicare revenue for this provider totals $1.4M while there is no Medicaid billing on file, making the practice effectively single-payer (Medicare-focused) in the available claims data. The absence of any Medicaid codes suggests this clinician does not routinely bill state Medicaid programs or treats a population primarily covered by Medicare.

Revenue concentration is high: the precomputed top 3 Medicare codes by revenue account for 86.5% of the provider’s total Medicare revenue, indicating dependence on a small set of drug administration codes. Those top drivers are J0129 (abatacept), J1602 (golimumab IV), and J9312 (rituximab), pointing to a practice model centered on biologic infusions or infusible specialty drugs rather than high-volume office visits.

The code mix and descriptions (J0129, J1602, J9312 plus administration codes 96365 and 96413) signal a service-line focus on infusion of biologic disease-modifying agents and procedural administration services. Substantial revenue from injectable biologic HCPCS codes alongside frequent use of initial infusion code 96365 indicates the provider delivers in-office IV therapies and manages ongoing infusion schedules rather than primarily providing brief E/M visits.

Competitive standing by code shows the provider has above-typical national volume for several high-revenue biologic codes but is not a national market leader. For example, J0129 ranks #235 of 1221 providers (81th percentile) and J1602 ranks #116 of 1041 providers (89th percentile), while J9312 ranks #49 of 317 providers (84th percentile); these placements indicate solid, regionally meaningful infusion volume but not dominant national market share.

The practice maintains relatively high outpatient E/M intensity for established visits: 99214 appears prominently with 718 claims and $60.3K revenue, and it ranks #24838 of 479517 providers nationally (95th percentile), described in the source as "notably above typical national volume for this code." This suggests a patient panel that requires moderate-complexity management visits in addition to infusion services.

Several administration and chemotherapy-related add-on codes appear at typical national volumes (96365, 96413, 96415), supporting that infusion sessions and time-based chemotherapy/biologic administration contribute meaningfully to operations beyond drug acquisition. Those codes are consistent with routine initial infusion, ongoing infusion time, and additional infusion hours being billed as part of patient care workflows.

Although this provider has meaningful activity in high-revenue biologic codes, many lower-revenue services (e.g., G0439 wellness visits, G0444 depression screening, routine venipuncture 36415) are at very low volumes compared with peers, indicating the practice may prioritize infusion/medication management over primary-preventive or screening services typically seen in general outpatient clinics. This profile reinforces the interpretation of a specialty infusion-focused rheumatology practice rather than a broad ambulatory generalist practice.
