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

Why is the Medicaid comparison limited to Minnesota 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. Minnesota (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.

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

Key Findings

This provider bills almost exclusively to Medicare (Total Medicare revenue: $1.3M) and has no Medicaid billing on file, making the practice effectively single-payer from a public-program perspective. The platform’s precomputed metric shows the top 3 Medicare codes account for 94.2% of this provider’s Medicare revenue, indicating a highly concentrated revenue base.

Revenue is dominated by three drug-injection codes: J2350 ($841.8K, 66.2% of this provider's total Medicare revenue), J1569 ($180.7K, 14.2%), and J1568 ($175.7K, 13.8%). Because those three line items together account for the precomputed 94.2% share, the business economics of this practice are driven almost entirely by reimbursement for infused biologic and immunoglobulin products rather than routine office evaluation payments.

The code mix (large volumes of J2350, J1569, J1568 alongside several infusion administration codes such as 96365, 96366 and additive chemotherapy codes) is consistent with a neurology-focused infusion practice providing biologic therapies like ocrelizumab and IVIG. Typical E/M codes (for example 99215 with $19.7K revenue, 159 claims) represent only a small fraction of total Medicare revenue, suggesting that face-to-face clinic visits are a secondary revenue stream compared with drug administration.

On national competitive standing for the top drug, J2350 ranks #31 of 105 providers nationally (71th percentile) and is labeled in the data as "typical, unremarkable volume for this code," which indicates the provider is a moderate-volume participant for ocrelizumab at the national level rather than a dominant outlier. This pattern reduces the likelihood that the practice is an unusually large national center for that single drug despite the high dollar concentration.

The two IVIG line items also reflect middle-to-upper quartile national positioning without being extreme outliers: J1569 ranks #182 of 542 providers (66th percentile) and J1568 ranks #83 of 381 providers (78th percentile), both described as "typical, unremarkable volume for this code." Together, these rank/percentile signals point to a practice with meaningful specialty volume but not top-of-market dominance in either IVIG product.

Operational sensitivity: because a very large share of revenue comes from high-cost injectable biologics and immunoglobulins (see J2350, J1569, J1568), the practice’s topline is likely sensitive to formulary changes, acquisition-pricing shifts, and reimbursement policy updates for those products. Administrative and inventory management for specialty drug administration are likely central operational considerations for this provider.

Despite the high concentration in infused drugs, many procedure codes across the list are characterized in the dataset as "typical, unremarkable volume for this code," including infusion administration and minor injection codes. There are also low-percentile entries (for example G2212 at the 4th percentile and J0897 at the 10th percentile) which the file still labels as "typical, unremarkable volume for this code," suggesting no individual code besides the top three stands out as a statistical extreme in the available Medicare sample.

The provider’s NPI was enumerated on 2006-06-07 (~20 years ago), indicating a long-tenured billing presence in Medicare that supports continuity of the specialty infusion pattern observed in the claims mix. Longevity combined with the concentrated drug-driven revenue profile frames this as an experienced, niche neurology infusion operation rather than a newly established clinic pivoting into specialty injectables.
