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

Why is the Medicaid comparison limited to North 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. North 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.

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 a single-payer Medicare clinician: Total Medicare revenue is $401.2K and there is "no Medicaid billing on file," so Medicaid does not contribute to this provider's recorded revenue. The absence of Medicaid billing indicates the provider's patient mix and revenue stream are concentrated in Medicare-covered inpatient work rather than a mixed payer panel.

Revenue is highly concentrated in a very small set of inpatient E/M codes: the precomputed top three codes (99232, 99233, 99223) account for 90.7% of this provider's total Medicare revenue. Individually, 99232 contributes 54.4% of Medicare revenue, 99233 contributes 19.5%, and 99223 contributes 16.8%, signaling that a handful of hospitalist services drive nearly all billed Medicare dollars.

The code mix and descriptions indicate a hospitalist-focused operation centered on inpatient and observation evaluation-and-management visits and time-based care. High shares for 99232 (subsequent inpatient moderate complexity), 99233 (subsequent inpatient high complexity), and 99223 (initial inpatient high complexity) point to regular, time-intensive inpatient encounters and initial admissions rather than outpatient clinic work; the presence of G0316 (prolonged inpatient/observation E/M) at low volume (0.5% of revenue) reinforces occasional prolonged encounters.

This provider ranks as a high-volume national outlier on key inpatient codes: 99232 ranks #319 of 177383 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code) and 99223 ranks #653 of 139583 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code). 99233 also sits well above typical national volume, ranking #2609 of 128818 providers nationally (98th percentile; notably above typical national volume for this code). These standings suggest the provider operates at volumes for those services that are uncommon relative to peers.

Discharge-management services are also notable: 99239 (discharge day management >30 minutes) generates 7.5% of Medicare revenue and ranks #556 of 62398 providers nationally (99th percentile; extreme outlier, far above typical national volume for this code). By contrast, 99238 (discharge ≤30 minutes) is a minor contributor at 1.0% of revenue and ranks #5861 of 35692 (83th percentile; typical, unremarkable volume for this code), which suggests a preference or practice pattern toward longer discharge-management encounters when billed.

Lower-complexity subsequent visit codes are rare in this profile: 99231 accounts for only 0.2% of Medicare revenue and ranks #37741 of 50953 providers nationally (24th percentile; typical, unremarkable volume for this code). The near absence of low-intensity codes alongside dominance of high- and moderate-complexity codes suggests a practice orientation toward sicker inpatients and higher-acuity management.

Provider tenure is established: NPI was enumerated 2013-07-01 (~13 years ago), indicating more than a decade of credentialing and activity under this NPI. That tenure, combined with the concentrated, high-volume hospitalist code mix, supports an interpretation of an experienced inpatient clinician embedded in sustained hospital workflows.

Strategic and business implications from the data: the combination of concentrated Medicare revenue (top 3 codes = 90.7%), extreme-national-volume standing on several inpatient codes, and no Medicaid billing suggests this clinician's revenue is tightly coupled to inpatient Medicare volume and hospital admission/rounding patterns. This concentration can be advantageous for negotiating hospitalist staffing roles or focusing operational improvements on inpatient throughput, but it also means limited payer diversification and heavy dependence on continued Medicare inpatient volume for revenue continuity.
