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

Why is the Medicaid comparison limited to Tennessee 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. Tennessee (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

ROBERT JOHNSON is a Hematology & Oncology Physician whose Medicare billing mix is dominated by high-cost oncology infusions — the top revenue drivers are branded immunotherapy and monoclonal antibody products (notably J9271, J9299, and J9144). The presence of these specific J‑codes indicates this provider operates an infusion-forward oncology practice that delivers checkpoint inhibitors and targeted monoclonal therapies alongside supportive agents.

Revenue concentration is high: the precomputed top 3 Medicare codes (J9271, J9299, J9144) together account for 66.4% of this provider's total Medicare revenue. Individually those codes generated $920.2K (34.7%), $499.2K (18.8%), and $342K (12.9%) of Medicare revenue respectively, showing the business is heavily dependent on a small set of expensive drugs.

Payer mix is effectively single-payer Medicare: lifetime Medicare revenue is $2.8M while Medicaid shows none on file. This lack of Medicaid billing suggests limited exposure to Medicaid populations or billing arrangements that do not route through state Medicaid, concentrating commercial and public reimbursement risk on Medicare.

On competitive standing the provider is a meaningful but not dominant national participant for its top therapies: J9271 ranks #328 of 1841 providers nationally (82th percentile; typical, unremarkable volume), J9299 ranks #151 of 505 providers nationally (70th percentile; typical, unremarkable volume), and J9144 ranks #266 of 615 providers nationally (55th percentile; typical, unremarkable volume). These percentiles indicate above-average utilization for some immunotherapies but not a top-tier national dominance in these agents.

The mix includes a suite of supportive and adjunctive injectable therapies — J1569 ($130.9K, 4.9%), J0897 ($129.6K, 4.9%), and J2353 ($128.8K, 4.9%) appear in the top codes — which signals routine management of treatment-related complications and bone health in addition to primary oncology care. National ranks for these codes (for example J2353 ranks #10 of 18 providers nationally, 47th percentile; J1569 ranks #256 of 542, 53th percentile) are generally in the typical range, consistent with a comprehensive infusion practice rather than a narrow specialty outlier.

E/M and ancillary service indicators show a substantial office and in‑house monitoring footprint: 99214 generated $45.5K and ranks #46306 of 479517 providers nationally (90th percentile), while lab and phlebotomy codes such as 85025 ($15.2K, 97th percentile rank) and 36415 ($11.4K, 98th percentile rank) are also high relative to peers. These patterns are consistent with frequent clinic visits and on-site laboratory monitoring to support ongoing infusion therapy.

The provider has long tenure in Medicare billing, with NPI enumerated (registered) 2006-07-07 (~20 years ago), indicating an established practice likely with stable referral pathways and operational processes for infusion delivery. Longevity combined with the concentrated drug mix suggests entrenched clinical workflows around high-cost biologic administration.

From an operational and revenue-risk perspective, dependence on a small number of high-revenue biologic agents creates concentration sensitivity: the top three codes represent 66.4% of Medicare revenue, so shifts in utilization, payer policy, or access to these specific drugs could materially affect top-line Medicare receipts. The absence of Medicaid billing further concentrates payer exposure and reduces diversification across public payers.
