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.

Key Findings

This provider is effectively single-payer in the dataset: lifetime Medicare revenue is $39.4K and there is no Medicaid billing on file. The absence of Medicaid claims means any Medicaid-facing capacity, referral patterns, or revenue diversification cannot be observed from this record and the practice appears reliant on Medicare as its only reported public payer source.

Revenue is highly concentrated in a small set of office evaluation-and-management codes: the top 3 Medicare codes (99213, 99204, 99203) account for 80.8% of this provider's total Medicare revenue. That concentration indicates the practice’s Medicare business is driven largely by clinic-based visits rather than high-revenue surgical procedures or facility-based services.

The code mix supports an office-based orthopaedic practice model focused on consultations and outpatient management. The highest two codes by revenue are 99213 (215 claims, $75 avg paid/claim, $16.1K revenue, 40.8% of Medicare revenue) and 99204 (89 claims, $136 avg paid/claim, $12.1K revenue, 30.6% of Medicare revenue), reflecting a mix of established-patient follow-ups and longer new-patient evaluations rather than major operative billing.

Procedure and imaging codes appear as secondary revenue sources consistent with an ambulatory orthopaedic clinic: 20610 (43 claims, $54 avg paid/claim, $2.3K revenue, 5.9%) and 73564 (35 claims, $32 avg paid/claim, $1.1K revenue, 2.8%) show the provider performs joint injections and localized X-ray imaging, supplementing E/M visits with point-of-care procedures.

Competitive standing by code shows modest to typical national participation rather than dominance. For example, 99213 ranks #90667 of 457151 providers nationally (80th percentile; typical, unremarkable volume for this code), 99204 ranks #32360 of 227068 (85th percentile; typical, unremarkable volume for this code), and 99203 ranks #58743 of 161519 (63th percentile; typical, unremarkable volume for this code), indicating the provider has steady but not exceptional claim volumes for common orthopaedic outpatient codes.

There are some operational anomalies in the claims mix that merit attention: J0665 appears with 498 claims but $0 revenue (0.0% of Medicare revenue) and ranks #125 of 335 providers nationally (63th percentile), while J3301 shows 190 claims but only $190 revenue (0.5%). These patterns—high claim counts paired with negligible recorded Medicare payments for certain injections—could reflect billing of low-reimbursed supply items, bundling, or data reporting/processing artifacts rather than high income sources.

Tenure in the public records is long-standing: the NPI was enumerated on 2005-05-31 (~21 years ago), indicating the provider has been credentialed and potentially practicing for two decades according to enrollment data. This duration aligns with a steady outpatient practice profile rather than a recent entrant.

Given the combination of concentrated E/M revenue (top 3 = 80.8%), modest procedure income, and no Medicaid billing, the provider appears to operate a small, outpatient-focused orthopaedic clinic that depends on Medicare office visits for most revenue. For payers and network analysts, this profile suggests limited Medicaid exposure and limited reliance on high-cost procedural or facility claims when modeling network capacity or competitive positioning.
