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.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider’s Medicare revenue profile is heavily biologics-centric: the top three revenue-driving HCPCS codes are J0129, J9312, and J1602, which together account for 82.2% of total Medicare revenue. Those codes correspond to abatacept, rituximab, and golimumab infusions — therapies consistent with a rheumatology infusion clinic or high-volume biologics administration practice rather than primarily office-based evaluation and management care.

Medicare dominates this provider’s public-payer mix: Total Medicare revenue is $4.1M while there is no Medicaid billing on file, indicating an effectively single-payer (Medicare-only) footprint in the publicly reported data. Analysts should treat the practice as relying on Medicare fee-for-service flows for its public revenue and not expect Medicaid contract/clause exposure from these files.

Several injectable biologic codes are extreme outliers versus national peers, signaling an unusually concentrated procedural footprint. J9312 (rituximab) ranks #2 of 317 providers nationally and is labeled a 100th percentile extreme outlier, while J0129 (abatacept) ranks #12 of 1221 providers at the 99th percentile and J1602 (golimumab) ranks #10 of 1041 providers at the 99th percentile, all far above typical national volumes for these codes.

Despite the dominance of high-dollar biologic codes, the practice shows relatively modest E/M volume on Medicare: 99215 and 99214 appear in the top-25 but account for only small portions of revenue ($11.9K and $5.5K respectively), and lower-level E/M code 99213 is negligible by revenue and ranks in the low national percentiles. This mix reinforces an infusion-centered service line with limited office-visit revenue contribution in Medicare claims.

Beyond the top three biologics, the provider also reports notable volumes of ancillary infusion-related codes: 96365, 96413, and 96415 appear with ranks described as notably above typical or extreme outlier percentiles, which aligns with repeated IV infusion sessions and extended infusion times common in an infusion clinic workflow. These add-on and initial infusion codes support the operational inference of long chair-time and repeated medication administration.

National competitive standing is concentrated and extreme for specific drug administration codes but more typical or unremarkable for others: while J9312 and J0129 mark the provider as a national outlier and dominant participant for those drugs, codes such as J3262 and J1745 are in more typical percentile ranges (74th and 92th percentiles respectively), indicating the provider’s outsized role is specific to certain biologics rather than a uniformly dominant national presence across all rheumatology injectables.

Provider tenure is long: the NPI was enumerated on 2006-06-08 (~20 years ago), suggesting an established practice history that could support sustained referral relationships or long-term infusion operations; this tenure may help explain stable high-volume biologic administration reflected in Medicare billing.
