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 Arizona for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Arizona 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. Arizona (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 is effectively single‑payer: total Medicare revenue is $3.5M while there is no Medicaid billing on file, so the practice’s Medicare business drives its entire public‑payer footprint and financial scale. Analysts should treat Medicare trends here as representative of the provider’s public‑payer activity rather than a mixed‑payer profile.

Revenue is highly concentrated in a small set of biologics: the precomputed top 3 Medicare codes by revenue account for 51.2% of this provider's total Medicare revenue, with J0897, J1602, and J0129 the principal drivers. That concentration implies the practice’s financial performance is sensitive to utilization and reimbursement for a handful of high‑revenue injectable therapies.

The code mix is consistent with a rheumatology practice that operates in‑office infusion and injection services: dominant biologic drug codes (J0897, J1602, J0129, J3111, J3262) combined with high volumes of infusion administration codes (96413, 96401, 96415) point to routine provision of parenteral biologic and chemotherapy‑style infusions rather than only clinic visits or self‑administered medications. This suggests an operational model that includes an infusion suite, staff for IV/subcutaneous administration, and drug procurement infrastructure.

For certain biologic agents this provider is a national outlier: J0897 ranks #55 of 10057 providers nationally (99th percentile; extreme outlier) and J1602 ranks #36 of 1041 providers nationally (97th percentile; notably above typical national volume). Those rank/percentile positions indicate this clinician is an unusually large national volume reporter for those specific drug codes compared with peers.

Infusion and chemotherapy administration activity is also atypically high versus peers: 96413 ranks #110 of 7514 providers nationally (99th percentile; extreme outlier) and 96401 ranks #59 of 3868 providers nationally (99th percentile; extreme outlier), while 96415 ranks at the 95th percentile (notably above typical). These administration code standings corroborate the practice’s operational emphasis on delivering frequent, supervised infusions.

Office evaluation and management volumes are above typical national levels as well: 99214 is ranked #8616 of 479517 providers nationally (98th percentile; extreme outlier) and 99215 is ranked #2135 of 145531 providers nationally (99th percentile; extreme outlier). Elevated E/M volumes alongside high infusion throughput suggest the practice manages substantial ongoing care and follow‑up visits for complex, therapy‑dependent patients.

Ancillary diagnostics and procedures are present but represent modest shares of revenue: routine labs (82306, 80053, 85025, 86140), DEXA bone density (77085), imaging (73120), joint procedures (20611), and intra‑articular products (J7328) appear in the top 25 but at much smaller revenue percentages. This pattern is consistent with an integrated outpatient rheumatology practice that supplements drug and infusion services with basic diagnostics and office procedures.

The provider shows long tenure in Medicare: NPI enumerated (registered) 2006-12-14 (~20 years ago), indicating an established practice presence. Coupled with the concentrated biologic revenue and repeated extreme‑percentile ranks on both drug and infusion codes, the data point to a mature, infusion‑oriented rheumatology operation with a pronounced Medicare focus.
