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

Why is the Medicaid comparison limited to Colorado 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. Colorado (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 reported payer mix is effectively single‑payer: Total Medicare revenue is $1.3M and Medicaid revenue is none (no Medicaid billing on file). The absence of Medicaid claims indicates the provider's activity is concentrated in the Medicare population with negligible state Medicaid participation.

Revenue is highly concentrated in a small set of biologic drug J‑codes: the top 3 Medicare codes by revenue (J1745, J3262, J9312) together account for 48.5% of this provider's total Medicare revenue. Individually those codes are J1745 $250.3K (19.3%), J3262 $200.8K (15.5%), and J9312 $177K (13.7%), showing monoclonal antibody administrations are the core revenue drivers.

The code mix is consistent with an infusion‑oriented rheumatology practice that administers biologic therapies on site: top J‑codes include infliximab (J1745), tocilizumab (J3262), and rituximab (J9312), and additional biologics such as certolizumab (J0717) and abatacept (J0129) also contribute materially. The presence of infusion/chemotherapy administration CPTs (96413, 96415, 96365) alongside multiple J‑codes supports a clinician‑supervised infusion service rather than a visit‑only model.

Competitive standing across codes is mixed: for the top drug J1745 the provider ranks #93 of 1352 (93th percentile), indicating a comparatively active national position for infliximab, while J3262 and J9312 rank #302 of 618 (51th percentile) and #163 of 317 (48th percentile) respectively and are described as 'typical, unremarkable volume.' In short, the provider is a notable user of infliximab nationally but a more modest participant for several other biologics.

Several non‑drug services show notably high utilization relative to peers: 99215 (high‑complexity E&M) ranks #2959 of 145531 (98th percentile; notably above typical national volume) and 96415 (add‑on infusion hours) ranks #156 of 4959 (97th percentile; notably above typical national volume). These high percentiles imply above‑average rates of complex outpatient visits and extended infusion management compared with national peers.

Lower‑intensity office visit volume is limited, reinforcing the specialty/infusion focus: 99213 appears with 20 claims ($1.4K revenue, 0.1% of Medicare revenue) and ranks #399623 of 457151 (11th percentile), a low relative standing. The combination of concentrated drug revenue and fewer low‑level E&M claims aligns with a practice model centered on specialty infusion care rather than high‑frequency primary care visits.

The provider shows long tenure in Medicare billing, with NPI enumeration dated 2006-07-03 (~20 years ago). Coupled with $1.3M in Medicare revenue and sustained biologic infusion activity, this tenure supports the interpretation of an established outpatient rheumatology practice operating a clinician‑supervised infusion service.
