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

Why is the Medicaid comparison limited to Alaska 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. Alaska (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 practitioner: total Medicare revenue is $356.4K and there is no Medicaid billing on file. The absence of any Medicaid claims indicates Medicaid does not contribute to this provider’s documented payer mix.

Revenue is highly concentrated in a small set of inpatient E/M and discharge codes: the top three Medicare codes (99232, 99233, 99238) account for 74.6% of total Medicare revenue, with 99232 alone representing 37.3% and 99233 representing 27.0%. This concentration signals that a few high-volume hospital services drive the bulk of reported Medicare income.

The code mix strongly indicates a hospitalist-style inpatient practice: heavy use of 99232 and 99233 (subsequent hospital inpatient/observation care) together with 99238 (inpatient discharge day management) points to frequent inpatient follow-up and discharge management as core operational activities. Those codes’ descriptions align with a workflow centered on daily inpatient visits and discharge processing rather than predominantly outpatient clinic work.

There is measurable involvement in higher-acuity care but it is a secondary revenue source: 99291 (critical care) accounts for 8.4% of Medicare revenue, showing some critical care encounters are billed but do not dominate the billing profile. The 99291 rank at the 86th percentile is described as typical or unremarkable relative to national volumes, so critical care is a notable but not exceptional component.

For the top inpatient codes this provider is a national outlier: 99232 ranks #2114 of 177383 providers (99th percentile; extreme outlier) and 99238 ranks #67 of 35692 providers (100th percentile; extreme outlier), while 99233 ranks #3389 of 128818 providers (97th percentile; notably above typical national volume). These ranked positions indicate this clinician bills these specific inpatient services at volumes far above typical national peers.

The provider also bills nursing facility codes but they represent a modest share of revenue: 99309 is 4.1% of Medicare revenue, 99308 is 1.9%, and 99307 is 1.7%, all with middling national percentiles. This pattern suggests some SNF/subacute work supplements the core inpatient hospitalist activity but is not a primary revenue driver.

Claim counts reinforce the high-volume inpatient focus: there are 1.6K claims for 99232, 771 claims for 99233, and 443 claims for 99238, with average paid/claim values reported alongside these volumes. Those raw claim counts, combined with the percentile ranks, underline that the provider delivers a large number of subsequent inpatient visits and discharges relative to peers.

The provider’s NPI was enumerated on 2006-09-21 (~20 years ago), indicating long-tenure in the Medicare program; paired with the concentrated inpatient billing profile, this tenure suggests an established hospitalist practice pattern rather than a recent or transient billing footprint.
