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

Why is the Medicaid comparison limited to Guam 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. Guam (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

The provider’s billing mix is concentrated in hospital-based E/M services consistent with the listed taxonomy of Hospitalist Physician: the top revenue-driving codes are 99232, 99233 and 99223, which correspond to subsequent inpatient/observation visits (moderate and high complexity) and high-complexity initial inpatient visits. This pattern indicates the provider operates primarily as an inpatient hospitalist focusing on initial evaluation, complex decision-making, and follow-up management rather than outpatient or procedure-driven practice.

Revenue concentration is high: the precomputed top-3 share shows that the top 3 Medicare codes account for 85.8% of this provider's total Medicare revenue, with 99232 generating $14.8K (33.2%), 99233 generating $12.1K (27.2%), and 99223 generating $11.3K (25.4%) of Total Medicare revenue: $44.6K. Those three codes dominate the Medicare revenue stream and create a tight dependence on hospital inpatient E/M encounters.

Payer mix is effectively single-payer: Total Medicare revenue: $44.6K and Total Medicaid revenue: none (no Medicaid billing on file). The absence of Medicaid billing suggests the provider’s exposure and revenue risk are concentrated in Medicare payment policy and hospital contracting rather than a mixed payer portfolio.

Competitive standing by code is modest and broadly described as typical: 99232 ranks #40673 of 177383 providers (77th percentile), 99233 ranks #48429 of 128818 providers (62th percentile), and 99223 ranks #33355 of 139583 providers (76th percentile). The underlying data labels these volumes as typical, unremarkable volume for these codes, which indicates the provider is not a national leader on these services but operates at a common activity level for hospitalist E/M care.

Lower-volume adjunct codes underscore the inpatient focus but also show limited breadth: 99239 (discharge day management) produced $4K (9.1%) with 44 claims and is ranked #35960 of 62398 providers (42th percentile; described as typical, unremarkable volume for this code), and 99222 (initial moderate-level inpatient visit) produced $2.3K (5.1%) with 22 claims and is ranked #70203 of 117621 providers (38th percentile; described as typical, unremarkable volume for this code). These secondary codes support the narrative of a hospitalist workflow that includes discharges and moderate-complexity admissions but at modest national standing.

Operational implication: the high share of subsequent inpatient visit codes (99232 and 99233 together represent $14.8K and $12.1K respectively, or 33.2% and 27.2% of Total Medicare revenue: $44.6K) suggests day-to-day inpatient rounding and follow-up care are the primary revenue drivers. For payers and network planners, the provider appears optimized for inpatient throughput and complex inpatient decision-making rather than ambulatory or procedure-centric services.

Tenure and credentialing stability are evident: the NPI was enumerated 2007-04-23 (~19 years ago), indicating long-standing enrollment in Medicare which supports continuity of provider relationships and established billing patterns over time. This longevity reduces the likelihood that the observed code mix is a short-term artifact and suggests the current inpatient-focused pattern is persistent.

Financial scale is small in absolute terms: with Total Medicare revenue: $44.6K and Medicare claims counts concentrated in a few codes (e.g., 231 claims for 99232, 125 for 99233, 84 for 99223), the provider represents a modest revenue footprint relative to larger hospitalist groups. Analysts should therefore treat this entity as a typical, lower-volume hospitalist contributor when modeling market capacity or negotiating rates rather than a high-volume system-level partner.
