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

Why is the Medicaid comparison limited to Alabama 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. Alabama (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 is effectively single‑payer from a claims perspective: total Medicare revenue is $2.6M and there is no Medicaid billing on file ("none"). The practice’s revenue is therefore highly concentrated in Medicare, and precomputed metrics show the top 3 Medicare codes by revenue account for 51.6% of this provider's total Medicare revenue, indicating reliance on a small set of therapy codes.

The code mix is consistent with an office‑based hematology/oncology infusion practice that administers high‑cost monoclonal antibodies and supportive biologics: the top revenue drivers are J9271 (pembrolizumab, $602K), J9144 (daratumumab, $342K) and Q5127 (pegfilgrastim‑fpgk, $305.7K). Chemotherapy administration codes such as 96413 and facility/infusion follow‑on code G0498 also appear on the top list, reinforcing that the practice delivers onsite infusion and chemo services rather than only consultative care.

Revenue concentration is pronounced: the three top codes J9271, J9144, and Q5127 together make up 51.6% of Medicare revenue, with individual shares of 24.8% for J9271, 14.1% for J9144, and 12.6% for Q5127. That level of concentration around a few injectable therapies suggests business sensitivity to utilization patterns, drug mix, and payer reimbursement for those specific agents.

Competitive standing varies by drug: Q5127 ranks #1 of 30 providers nationally (100th percentile) and is flagged as "notably above typical national volume," implying this provider is a national leader for that pegfilgrastim biosimilar. By contrast, J9271 (rank #758 of 1841, 58th percentile) and J9144 (rank #266 of 615, 55th percentile) are described as typical, unremarkable volumes nationally, indicating the provider is mid‑pack for several other high‑value oncology agents.

Outpatient visit and evaluation volumes are unusually high relative to peers: 99214 appears with 1.1K claims and $97.3K revenue and is classified as an "extreme outlier, far above typical national volume" (98th percentile). 99215 also ranks at the 98th percentile and is labeled "notably above typical national volume," which together suggest a large established patient panel and substantial office‑based management of complex oncology cases.

The practice delivers substantial ancillary services in‑house: lab and phlebotomy codes such as 80053 (2.3K claims, $22.6K revenue, 98th percentile), 85025 (2.3K claims, $18.7K revenue, 98th percentile) and 36415 (2.1K claims, $16.7K revenue, 99th percentile) are all listed as typical but at very high national percentiles. This pattern is consistent with an infusion clinic that performs routine monitoring and specimen collection for oncology patients rather than outsourcing those services.

Supportive care and specialty injectable use is notable across multiple codes beyond the top three: J1568 (IV immune globulin, $154.8K, 6.4% of Medicare revenue; rank #100 of 381, 74th percentile) and J1437 (ferric derisomaltose, $97.6K, 4.0% of Medicare revenue; rank #90 of 581, 84th percentile) indicate regular use of non‑oncologic biologics and iron therapies commonly used in hematology/oncology practice. Several biosimilar pegfilgrastim entries (Q5127, Q5108, Q5122) across the top codes further underscore reliance on growth‑factor support as part of the care mix.

The provider has an established billing history, with the NPI enumerated on 2008‑08‑18 (~18 years ago). Combined with the drug mix, high E/M volumes, and in‑office ancillary services, the tenure supports the interpretation of a stable, long‑running oncology infusion practice based in Huntsville, AL rather than a new or primarily consultative clinician.
