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

Why is the Medicaid comparison limited to Arkansas 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. Arkansas (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

MARIANN HARRINGTON is a Hematology & Oncology Physician in LITTLE ROCK, AR whose Medicare lifetime revenue totals $2.7M and who has no Medicaid billing on file (Medicaid: none). The provider’s NPI was enumerated on 2005-11-16 (~21 years ago), indicating long tenure in the Medicare program and an established practice footprint in the market.

Revenue is highly concentrated in a small set of oncology biologics and immunotherapies: the precomputed top three Medicare codes (including J9271, J9022, and J9299) account for 55.5% of this provider’s total Medicare revenue. In particular J9271 represents $928.8K or 35.7% of Medicare revenue, making pembrolizumab the single largest revenue driver for this clinician.

The code mix and service lines indicate an infusion-heavy oncology practice that administers checkpoint inhibitors and supportive oncology agents: high-revenue drug codes include J9271 (pembrolizumab), J9022 (atezolizumab), J9299 (nivolumab), plus supportive agents such as J0897 (denosumab) and J2506 (pegfilgrastim). Significant administration and chemotherapy procedure volume (96413, 96375, 96365, 96417) plus frequent lab monitoring codes (85025, 80053, 82378, 86300) suggest integrated outpatient infusion services with on-site or closely coordinated diagnostics.

Competitive standing across the provider’s top drug codes is mixed: J9271 is a mid-ranking national participant (ranks #320 of 1841, 82th percentile; labeled typical, unremarkable volume), J9022 sits at ranks #18 of 39 (55th percentile; typical, unremarkable volume), and J9299 is lower nationally (ranks #357 of 505, 29th percentile; typical, unremarkable volume). These ranks imply the clinician is not a dominant national provider of these agents but maintains a meaningful, practice-defining volume of pembrolizumab.

Several utilization measures are statistical outliers relative to national benchmarks for non-drug services, reflecting unusually high throughput in office visits and infusion-related activity. The E/M code 99214 is an extreme outlier (2K claims, $166.4K revenue; characterized as far above typical national volume), and infusion add-on/related code 96375 is also labeled an extreme outlier (1.5K claims, $16K revenue); chemotherapy administration 96413 is noted as notably above typical national volume (751 claims, $65.3K). These patterns are consistent with a high-volume outpatient oncology clinic workflow.

Lab and supportive-service volumes reinforce the infusion practice profile: 85025 (CBC) shows 5.4K claims ($43K revenue), 36415 (venipuncture) 4.7K claims ($37.9K revenue), and tumor marker testing such as 82378 (CEA) has 1.1K claims ($21.6K revenue). This combination of frequent blood draws, panels, and cancer markers alongside biologic drug administration indicates the practice carries out both therapeutic infusions and the attendant monitoring needed for oncology care.

Payer mix and business risk are concentrated toward Medicare: with $2.7M reported Medicare revenue and no Medicaid billing on file, the provider is effectively a Medicare-only billing entity in the available data. That single-payer exposure should be considered in network/contracting and population-access analyses, because there is no recorded Medicaid volume to diversify public payer exposure in the dataset.
