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.

Key Findings

This provider is effectively a Medicare-only billing practice: total Medicare revenue is $1.4M while Medicaid revenue is listed as none, indicating no Medicaid billing on file. The absence of any Medicaid claims suggests payer exposure is concentrated in the Medicare program rather than a mixed Medicaid/Medicare patient base.

Revenue is highly concentrated in a small number of biologic drug administration codes: the top 3 Medicare codes by revenue account for 54.8% of this provider's total Medicare revenue. Those top codes are J0129 ($355.3K, 25.3%), J3262 ($273.6K, 19.5%), and J1602 ($141K, 10.0%), showing a dependence on a handful of high-cost injectable agents.

The code mix points to an infusion- and injection-centered rheumatology practice that bills for physician-administered biologics and supportive infusion services rather than office E/M care. High-revenue drug codes such as J0129 (abatacept), J3262 (tocilizumab), J1602 (golimumab) and J1745 (infliximab, $114.4K, 8.1%) dominate, while office visit codes like 99214 ($20.5K, 1.5%) and 99213 ($11.8K, 0.8%) capture only a small share of total Medicare revenue.

Competitive standing for the top revenue drivers is modestly above-median but not dominant nationally: J0129 ranks #452 of 1221 providers (63th percentile; typical, unremarkable volume for this code), J3262 ranks #205 of 618 providers (67th percentile; typical, unremarkable volume for this code), and J1602 ranks #491 of 1041 providers (53th percentile; typical, unremarkable volume for this code). These ranks indicate this provider is a regular regional participant for these biologics rather than a national outlier or market leader.

There are some contrasting percentile signals across secondary codes that affect the revenue profile: 96413 (chemotherapy administration) is listed at the 91th percentile (typical, unremarkable volume for this code) with $54.8K revenue, while J9312 (rituximab) is at the 8th percentile (typical, unremarkable volume for this code) with $100.8K revenue. Although the dataset uniformly labels volumes as "typical, unremarkable," the differing percentiles show pockets of relatively higher or lower national activity on specific drugs and administration procedures.

The provider has an established NPI tenure that supports experience in this service mix: NPI enumerated 2012-04-04 (~14 years ago). This length of enumeration is consistent with a sustained, procedure-driven rheumatology practice able to maintain recurring biologic administration revenues over time.

Operational and reimbursement sensitivity is concentrated in drug administration and infusion services rather than evaluation-and-management volume, which creates exposure mainly to Medicare drug payment policies and biologic pricing dynamics. Supporting codes such as J7050 (normal saline, 382 claims) and infusion add-on codes like 96415 (194 claims) appear in the mix, underscoring that a sizeable portion of revenue depends on office-based infusion workflows and supply/administration reimbursement rather than broad outpatient clinic visit billing.
