Answer Box: Getting Keytruda Approved in Washington

Keytruda (pembrolizumab) requires prior authorization from Blue Cross Blue Shield plans in Washington, including Premera and Regence. Your oncologist must submit clinical documentation proving medical necessity, including PD-L1 testing results for certain cancers and evidence of appropriate diagnosis staging. The fastest path: schedule a focused visit to review your cancer history, gather required biomarker tests, and help your provider prepare a comprehensive letter of medical necessity. If denied, Washington offers strong external review rights through Independent Review Organizations (IROs) via the Office of the Insurance Commissioner.

Set Your Goal: Understanding What Approval Requires

Blue Cross Blue Shield plans in Washington—including Premera Blue Cross and Regence BlueShield—require prior authorization for Keytruda before coverage begins. Your partnership with your oncologist is essential because they must provide specific clinical evidence that your insurance plan demands.

Coverage at a Glance

Requirement What It Means Where to Find It
Prior Authorization Mandatory approval before treatment Premera PA requirements
PD-L1 Testing Required for NSCLC, cervical, and other specific cancers FDA label for your cancer type
Step Therapy May need to try other treatments first Your plan's drug formulary
Site of Care Treatment at approved infusion centers Provider network directory

Your goal is to help your oncologist build an airtight case that demonstrates:

  • Your cancer diagnosis matches FDA-approved indications
  • Required biomarker testing supports Keytruda use
  • Previous treatments (if required) have failed or aren't appropriate
  • Keytruda is medically necessary for your specific situation

Visit Preparation: Building Your Clinical Story

Before your appointment, organize your medical journey into a clear timeline. This preparation saves valuable appointment time and ensures nothing important gets missed.

Symptom Timeline Checklist

Create a chronological list including:

  • Initial symptoms and when they started
  • Date of cancer diagnosis and staging
  • All treatments tried (chemotherapy, radiation, surgery, other immunotherapies)
  • Treatment outcomes (partial response, progression, intolerable side effects)
  • Current functional status (energy level, ability to work, daily activities)

Treatment History Documentation

Tip: Request records from previous oncologists 2-3 weeks before your appointment. Many offices need time to compile comprehensive treatment summaries.

Gather documentation of:

  • Previous chemotherapy regimens and cycle counts
  • Radiation therapy reports and dates
  • Surgical pathology reports
  • Imaging studies showing disease progression or response
  • Laboratory results, especially tumor markers

Side Effects and Contraindications

Document any treatments you couldn't tolerate or complete, including:

  • Dose reductions required
  • Treatment discontinuation reasons
  • Allergic reactions or contraindications

This information is crucial for step therapy exceptions and medical necessity arguments.

Evidence Kit: Gathering Supporting Documentation

Required Laboratory and Imaging

Your oncologist needs current documentation including:

  • Pathology report confirming cancer type and stage

  • Performance status assessment (ECOG or Karnofsky scale)

From Our Advocates: One patient we worked with had their Keytruda denial overturned at external review after their oncologist provided additional biomarker testing documentation that wasn't included in the original request. The key was demonstrating that their PD-L1 expression level met the threshold specified in Blue Cross's medical policy. This shows how important complete documentation is from the start.
