UnitedHealthcare IC Prior Authorization

UnitedHealthcare IC 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 generally expects prior authorization requests to be submitted electronically. Official resources describe submission through the UnitedHealthcare Provider Portal and EDI 278; some request types may also support fax, and telephonic submission is only allowed where specifically permitted or required. Requirements vary by plan and service category, and certain services may have separate program rules.
• Official UnitedHealthcare guidance is plan-specific in many areas; the exact prior authorization rule set depends on line of business, state, and sometimes delegated entity.
• Some programs, such as radiology or cardiology, have separate CPT lists, protocols, and exceptions.
• I did not find a single official source that cleanly maps 'UnitedHealthcare IC' to one uniform prior authorization policy.
