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

Why is the Medicaid comparison limited to California 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. California (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 footprint is the dominant and effectively sole public-payer activity: total Medicare revenue is $7.3M and there is no Medicaid billing on file, so the practice operates as a single-payer (Medicare) revenue stream in the available data. The absence of any Medicaid claims suggests limited participation in Medicaid-managed care or state programs in California.

Revenue is highly concentrated in a small set of high-cost injectable products: the precomputed top three Medicare codes (J1599, J1459, J1556) account for 77.6% of this provider’s total Medicare revenue. Those three codes individually represent $2.2M (29.4%), $1.8M (24.9%), and $1.7M (23.3%) of Medicare revenue respectively, indicating the practice’s financial profile is driven overwhelmingly by IV immune globulin administration.

The code mix and high volumes for immunoglobulin products point to an infusion-focused neurology practice: J1599, J1459, J1556 and J1569 are all immune globulin infusion products, and J1599 ($2.2M) and J1459 ($1.8M) are the single largest revenue generators. Coupled with substantial administration claims (96365: 1.1K claims, $67.6K revenue; 96366: 1.9K claims, $35.7K revenue), the activity pattern is consistent with a dedicated IV infusion service line rather than a primarily office-visit-driven practice.

This provider is a national leader for several IVIG products: J1599 ranks #1 of 11 providers nationally (100th percentile; notably above typical national volume) and J1459 ranks #1 of 44 providers nationally (100th percentile; extreme outlier, far above typical national volume). J1569 is also an outlier (rank #4 of 542, 99th percentile; extreme outlier), signaling dominant or atypically large market share for specific immune globulin formulations at the national level.

Market position is uneven across product brands: while J1599 and J1459 are at the top nationally, J1556 ($1.7M) ranks #7 of 46 providers (87th percentile; typical, unremarkable volume) and J1568 ($230.5K) ranks #58 of 381 (85th percentile; typical, unremarkable volume). This pattern suggests the provider concentrates volume on particular IVIG products while maintaining ordinary participation for other formulations.

Clinical office visit (E/M) billing contributes only a small fraction of revenue compared with infusions: 99215 generated $20K (0.3% of Medicare revenue) from 136 claims and 99205 generated $16.5K (0.2%) from 89 claims, while many E/M codes are single- to double-digit claim counts and sub-percent shares. The disparity between large drug/infusion revenue and modest E/M revenue reinforces that the practice’s business model centers on drug administration rather than routine clinic visits.

Infusion-related procedure volumes are unusually high relative to national peers: 96365 (initial IV infusion) and 96366 (additional infusion hours) appear as extreme outliers (96365 ranks #74 of 8873 providers, 99th percentile; 96366 ranks #17 of 2976 providers, 99th percentile), which supports the interpretation of sustained, high-throughput infusion operations rather than occasional infusions. Those high administration volumes align with the large counts reported for IVIG codes (e.g., J1459 49.3K claims, J1599 39.8K claims).

The provider has long tenure in Medicare billing, with NPI enumeration dated 2005-07-19 (~21 years ago), indicating an established practice history. Given the high concentration of Medicare revenue in a few IVIG products (top 3 = 77.6%) and no Medicaid activity, the business is both specialized and highly exposed to reimbursement or supply shifts in those specific drug lines, which is an important consideration for payer contracting and network planning.
