1 · Data vintage
Commercial rates: Transparency in Coverage in-network machine-readable files published under 45 CFR § 147.212, reporting month 2026-09-01 (file self-reported last_updated_on 2026-10-01, schema 2.0.0). Medicare benchmark: CY 2026 CMS Physician Fee Schedule, release RVU26C (PPRRVU2026_Jul_nonQPP + GPCI2026), conversion factor 33.4009. Provider identity and location: NPPES monthly full-replacement file, September 2026 (V2). Payers republish monthly; figures are a point-in-time extract, not a live feed.
2 · Statistical method
All percentiles are non-parametric with linear interpolation (no distributional assumption, no smoothing). We report the observed contract population for the county, not a sample estimate — no confidence intervals are implied. Records are included only where negotiated_type = "negotiated" and billing_class = "professional"; capitated, percentage-of-billed, per-diem and institutional arrangements are excluded.
3 · County assignment
Providers are assigned to counties by NPPES practice-location ZIP, mapped through the U.S. Census ZCTA-to-county relationship file. ZCTAs cross county lines; each ZCTA is assigned to its dominant county by land area, and ZCTAs where the target county is not dominant are excluded. Land-area share is a proxy for population share and may misclassify providers near county boundaries.
4 · Contract and coding variation
A single CPT code can carry different rates by modifier, place of service, provider licensure/taxonomy, product line, contract vintage, and group arrangement. In this pilot, CPT 90837 shows 20 distinct rates across 76 tax IDs, and psychiatrist-taxonomy rates run about 27% above clinical social worker rates. Rates shown are not modifier-adjusted. Your own contract may differ for legitimate reasons.
5 · Scope of this pilot
The Wake County figures reflect one payer network (UnitedHealthcare of North Carolina / Optum Health Behavioral Services), covering 96 of the 7,578 behavioral health NPIs registered in the county. They are not a whole-market or all-payer view and should not be read as “the Wake County rate.”
6 · No earnings or outcome representation
StarTorch LLC is an information services provider (NAICS 51). Revenue-gap figures are arithmetic illustrations of published rate differentials at user-supplied volumes. They are not projections, forecasts, guarantees, or representations of income. We do not promise any negotiation outcome, rate increase, or revenue result. Nothing here is legal, tax, actuarial, billing, or investment advice, and no professional relationship is created.
7 · Zero PHI
100% Zero PHI. Every input is a public government disclosure: payer rate files, the CMS fee schedule, the NPPES provider registry, and Census geography. We never request, receive, process, or store protected health information, patient records, claims, or remittance data. HIPAA does not apply to this data set. We are not a covered entity or a business associate, and no Business Associate Agreement is required or offered.
8 · Competitive conduct
Reports are prepared for, and delivered to, a single purchasing practice for evaluating its own contracts. StarTorch does not facilitate, host, or intermediate any exchange of pricing information among competing providers, and does not aggregate rates on behalf of any provider association or bargaining group. Source data is government-mandated public disclosure.
9 · Accuracy
Figures are derived from files published by the payers themselves. StarTorch makes no representation as to the accuracy, completeness, or timeliness of the underlying disclosures and does not independently verify them.
