UnitedHealthcare Prior Authorization

UnitedHealthcare prior authorization rules are often service-specific rather than universal, so the safest workflow is to confirm the requirement in the payer's provider resources before scheduling or submitting care. The notes below summarize the most actionable provider-side guidance captured in the research set for this payer.

At a glance

• UnitedHealthcare’s official provider materials direct providers to use the UnitedHealthcare Provider Portal to verify whether prior authorization is required, submit requests, upload attachments, and check status. The 2026 administrative guide also lists EDI 278/278N and telephonic submission where permitted; some plans keep fax capability because of state requirements, but providers can still use the portal for those plans.
• Requirements vary by plan type and by service category.
• Some services are excluded from the general commercial notification/prior-authorization workflow in the administrative guide.
• State rules may require fax capability for some plans, but the portal remains usable for submission where noted.
• The 2026 guide indicates updates by plan effective dates, so providers should confirm the member's specific plan tab before submitting.
