Appeals Process in Washington

Washington state provides robust appeal rights through multiple levels:

Internal Appeals

  • Deadline: 180 days from denial
  • Levels: 1-2 internal reviews
  • Submission: UnitedHealthcare member portal or written request
  • Timeline: Standard review within plan timelines

External Review

  • When: After exhausting internal appeals
  • Deadline: 180 days from final internal denial
  • Process: Independent Review Organization (IRO) through Washington Office of Insurance Commissioner
  • Timeline: 30 days for standard, 72 hours for expedited
  • Authority: RCW 48.43.535
From our advocates: We've seen Washington external reviews succeed when clinical documentation clearly demonstrates medical necessity and step therapy compliance. The IRO process removes the decision from the insurer's hands and often results in overturned denials for well-documented rare disease cases.

Appeals Documentation

  • Original denial letter
  • Complete medical records
  • Specialist evaluations
  • Failed treatment documentation
  • Medical necessity letter
