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

Why is the Medicaid comparison limited to South Dakota 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. South Dakota (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

LEANN BASSING is a long-tenured Rheumatology Physician with an NPI enumerated since 2007-08-01 (~19 years ago), indicating nearly two decades of Medicare participation and an established practice presence in Yankton, SD. This tenure supports a stable billing footprint focused on outpatient management and clinic-administered biologic therapy.

Medicare is effectively the sole public payer on file: Total Medicare revenue is $305.1K while there is no Medicaid billing on file. This provider should be considered single-payer (Medicare) in the public claims data, so any analysis of public payer mix must account for the absence of Medicaid activity.

Revenue concentration is high: the precomputed top 3 Medicare codes by revenue account for 82.6% of this provider’s total Medicare revenue, indicating that a small set of services drives the majority of payment. This level of concentration suggests the practice is specialized and materially dependent on a few high-revenue items for its Medicare income.

The dominant single code is J1602 (golimumab IV) which generates $206.5K and represents 66.1% of the provider’s Medicare revenue. Coupled with J0897 (denosumab) at $22.7K and 96365 infusion administration at $7.7K, the mix shows the practice focuses on in-office, provider-administered biologic infusions and related infusion services rather than primarily high-volume E/M office visits. This pattern is consistent with a rheumatology infusion/service-line model.

Competitive standing on key codes is mixed. For the largest revenue driver, J1602 ranks #331 of 1041 providers nationally (68th percentile), indicating a typical but neither dominant nor niche national volume for golimumab infusion; the provider is a modest participant among infusion providers. In contrast, J0897’s national rank (#8159 of 10057, 17th percentile) places the provider toward the lower end among peers administering denosumab, suggesting denosumab is a smaller, less-competitive line for this practice.

Visit-level E/M codes (99214, 99213, 99215) contribute materially but far less than infusion codes: 99214 accounts for $28.7K (9.2% of Medicare revenue) and ranks in the 82nd national percentile by provider volume for that code, indicating solid office-visit throughput relative to peers. Lower-volume new-visit and high-complexity codes (99205, 99204) appear but contribute small shares, consistent with an established patient population receiving chronic therapy and management.

Laboratory and routine support services (36415, 85025, 84450, 84460, 82040) appear across the top codes but each represents small revenue shares (each generally under 1.1% of Medicare revenue). Their presence aligns with an office-based specialty practice that performs on-site phlebotomy and common metabolic and liver panels to monitor biologic therapy safety.

Infusion administration codes beyond the primary drug (96365, 96415, J7050 saline) together indicate the practice bills for both initial infusion and continued infusion time plus supply items. These administration-related codes are typical for infusion services (96365 ranks in the 73rd percentile), reinforcing that in-office infusion is a core operational service rather than occasional care.
