UnitedHealthcare commercial provider contracts adhere to the “3-day (or 1-day) payment window” policy. We use certain Centers for Medicare & Medicaid Services (CMS) definitions when determining reimbursement for outpatient diagnostic and nondiagnostic services preceding an inpatient admission.
Including all diagnostic and nondiagnostic services on the claim helps improve payment consistency.
