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

Why is the Medicaid comparison limited to Georgia 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. Georgia (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: total Medicare revenue is $1.8M and there is no Medicaid billing on file. The absence of Medicaid claims indicates the provider’s Medicare business dominates revenue and patient-facing activity documented in public claims data.

Revenue is highly concentrated in a small set of therapies — the precomputed top‑3 Medicare codes account for 76.7% of this provider’s Medicare revenue. Those top contributors are A9607 (37.0% of Medicare revenue), J9271 (32.0%), and 99214 (7.7%), so a few high‑value services drive the majority of reported Medicare receipts.

The code mix aligns with Hematology & Oncology practice patterns: A9607 (Lutetium lu 177 vipivotide tetraxetan) and J9271 (pembrolizumab) indicate use of advanced oncologic therapeutics, while 99214 dominance reflects substantial ongoing outpatient management and evaluation and management visits. This combination suggests an operation focused on specialty drug administration plus frequent office‑based follow‑up.

Competitive standing varies by service line. For the radioligand A9607 the provider ranks #41 of 44 nationally (7th percentile), indicating a modest presence among the small national cohort billing that code; for pembrolizumab J9271 the provider ranks #732 of 1841 (60th percentile), a typical national volume; by contrast, 99214 is an extreme outlier, ranking #3450 of 479517 providers nationally (99th percentile), which indicates unusually high E/M volume relative to national peers.

Operational throughput is evident in claim volumes and drug administration codes: A9607 shows 2.6K claims with $249 avg paid/claim and $647.9K revenue, J9271 shows 14.4K claims with $39 avg paid/claim and $561.6K revenue, and supporting infusion/injectable codes such as J1568 (2.8K claims, $90.9K revenue) and J0897 (4.8K claims, $81.6K revenue) reflect an infusion‑centric workflow. These counts and payments underscore reliance on frequent drug administrations as a core revenue and activity driver.

Tenure and stability are notable: the NPI was enumerated on 2008-08-04 (~18 years ago), indicating an established billing history in Medicare data. That longevity, combined with concentrated specialty revenue, suggests an entrenched specialty practice rather than a recent entrant.

From a payer or network perspective, the combination of concentrated high‑value oncology therapeutics (A9607, J9271) and an extreme outlier level of 99214 visits warrants attention for utilization and network placement. Because top three codes account for 76.7% of Medicare revenue and there is no Medicaid activity, the provider represents a specialized Medicare revenue stream with limited apparent engagement in Medicaid populations.
