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

Why is the Medicaid comparison limited to Delaware 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. Delaware (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 revenue is highly concentrated: top 3 Medicare codes by revenue account for 91.4% of this provider's total Medicare revenue. In particular J9271 (pembrolizumab) alone represents $1M revenue (86.7% of this provider's total Medicare revenue) and 23.4K claims, signaling that most Medicare dollars reported for this NPI flow through a single high-cost oncology drug line item.

The code mix reflects an infusion-based hematology/oncology practice rather than a general outpatient clinic. Dominance of J9271 (pembrolizumab) together with chemotherapy administration codes such as 96413 (276 claims, $28.2K revenue) and multiple infusion/add-on codes (96417, 96415, 96411 and 96365 series) indicates routine in-office/clinic infusion services and immunotherapy delivery are the core service line.

Although J9271 is the primary revenue driver, the provider’s national competitive standing on that drug is modest: J9271 ranks #267 of 1841 providers nationally (85th percentile) and is described in the file as typical, unremarkable volume for this code. Similarly, 96413 ranks #2066 of 7514 providers nationally (72th percentile) and is also characterized as typical, suggesting the provider is a solid regional participant for these services but not a national high-volume center.

Non-drug professional revenue (office E/M and hospital E/M codes) appears secondary to infusion drug revenue. For example, 99213 accounts for $15.8K (233 claims, 1.4% of Medicare revenue) and 99215 accounts for $14.7K (105 claims, 1.3%), indicating that face-to-face evaluation and management visits support but do not drive the provider’s Medicare revenue base.

This provider bills Medicare but has no Medicaid billing on file (none below), making Medicare effectively the sole public payer in the available claims data. With total Medicare revenue reported at $1.2M and Medicaid revenue absent, payer mix for public programs is concentrated entirely in Medicare for the period captured.

Tenure and stability: the NPI was enumerated on 2010-06-15 (~16 years ago), which indicates an established practice history in the Medicare billing record and suggests the observed infusion-centric pattern has had time to stabilize.

Across the listed CPT/HCPCS codes there are no labels indicating extreme outlier behavior; most lines are recorded as typical or unremarkable volume. A few codes sit at lower national percentiles (for example J1437 ranks #448 of 581 providers nationally, 19th percentile) which points to below-median activity for certain supportive therapies, reinforcing that the practice’s scale is concentrated primarily in pembrolizumab administration rather than a broad high-volume mix of oncology drugs.
