What Affects Your Approval Timeline
Several factors determine how quickly Humana processes your Keytruda prior authorization request in Pennsylvania:
Benefit Type: Part C (medical benefit) requests take up to 30 days for standard review, while Part D (prescription benefit) requests are completed within 72 hours for standard coverage determinations. Starting January 2026, CMS is reducing Part C timelines to just 7 calendar days.
Complexity of Criteria: Keytruda requires extensive biomarker testing documentation. Missing PD-L1 expression levels, MSI-H status, or tumor mutational burden results will delay your approval while additional testing is ordered.
Documentation Completeness: Complete submissions with staging workup, treatment history, and medical necessity letters move through review queues faster than incomplete requests requiring additional information.
Note: Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters and plan policies to draft point-by-point rebuttals aligned to each payer's specific requirements.
Pre-Submission Preparation (0-2 Days)
Essential Documentation Checklist
Before your oncologist submits the prior authorization, ensure these documents are ready:
Clinical Documentation
- Primary cancer diagnosis with ICD-10 codes
- Complete TNM staging classification
- Pathology reports confirming tumor type
- Recent imaging and staging workup
Biomarker Testing Results (Critical)
- PD-L1 expression levels with specific test values
- MSI-H (microsatellite instability-high) status where indicated
- TMB-H (tumor mutational burden-high) status where applicable
Treatment History
- Documentation of prior therapies attempted and failed
- Specific dates and outcomes of previous treatments
- Reasons for discontinuation (progression, intolerance, contraindications)
- Patient performance status (ECOG 0-2 typically required)
Verification Steps
Call Humana member services at the number on your insurance card to confirm current prior authorization requirements and submission methods. Verify your oncologist is registered in Humana's provider network and has access to their online portal.
Submission to Initial Review (1-5 Days)
Pennsylvania Turnaround Rules
Pennsylvania state law requires health insurers to make utilization review decisions within 2 days for urgent cases and 5 days for standard cases. However, this applies to commercial plans, not Medicare Advantage plans like Humana, which follow federal Medicare timelines.
What Reviewers Check First
Humana's initial review focuses on:
- FDA-approved indication match: Does your diagnosis align with Keytruda's approved uses?
- Required biomarkers: Are PD-L1, MSI-H, or TMB-H results included and meet threshold requirements?
- Line of therapy: Is this first-line treatment or have required prior therapies been documented?
- Prescriber qualifications: Is the request from an appropriate oncology specialist?
Submission Methods
Your oncologist can submit through:
- Humana provider portal (fastest processing)
- Fax: 800-594-5309
- Phone: 866-488-5995 (providers)
Additional Information Requests (1-7 Days)
If Humana requests additional information, respond within 14 days to avoid automatic denial. Common requests include:
- Updated staging scans if previous imaging is over 3 months old
- Specific biomarker test reports with laboratory reference ranges
- Detailed treatment timeline with exact dates and outcomes
- Medical necessity letter addressing specific denial concerns
How to Respond Quickly
Contact your oncologist immediately upon receiving an additional information request. Many delays occur when patients don't realize their clinic needs to provide supplemental documentation promptly.
Decision Window & Outcomes
Typical Outcomes
Approval: You'll receive a coverage determination letter specifying the approved duration (typically 6-12 months for cancer treatments) and any quantity limits.
Partial Approval: Coverage may be approved with modifications like reduced frequency or shorter duration than requested.
Denial: The letter will specify exact reasons for denial, which become crucial for your appeal strategy.
Reading Approval Letters
Look for:
- Approved treatment duration
- Quantity limits per administration
- Site of care restrictions (hospital vs. infusion center)
- Renewal requirements and timing
If Denied: Appeal Timelines
Internal Appeals with Humana
You have 65 days from the denial notice to file an internal appeal. Humana must decide within:
- 30 days for standard Part C appeals
- 72 hours for expedited appeals when health is at risk
Pennsylvania External Review
After exhausting Humana's internal appeals, you can request external review through Pennsylvania's Independent External Review Program within 4 months of your final denial. This state-supervised process has overturned approximately 50% of denials in its first year.
Important: Pennsylvania's external review applies only to commercial insurance plans, not Medicare Advantage. For Medicare appeals, you'll need to follow federal Medicare appeal procedures through Medicare.gov.
Fast-Track Options
Request expedited review when:
- Waiting poses serious health risks
- Cancer progression is documented
- Treatment delays could affect outcomes
Your oncologist must certify medical urgency in writing for expedited processing.
Renewal Cycles & Reauthorization
Annual Reauthorization Requirements
Humana requires annual reauthorization for Keytruda, even when treatment continues successfully. Start the renewal process 30-45 days before your current approval expires to avoid treatment interruptions.
What Changes Renewal Speed
Faster renewals when you provide:
- Updated staging showing stable disease or response
- Continued good performance status
- No significant toxicities requiring dose modifications
- Consistent treatment adherence
Slower renewals occur with:
- Disease progression requiring regimen changes
- New toxicities or complications
- Changes in biomarker status
- Gaps in treatment documentation

Time-Saving Tips
Portal Usage
Use Humana's provider portal rather than fax or mail submissions. Electronic submissions are processed faster and provide real-time status updates.
Bundled Evidence Strategy
Submit all required documentation together in the initial request rather than piecemeal submissions. Include:
- Complete biomarker panel results
- Staging workup with recent scans
- Comprehensive treatment history
- Medical necessity letter addressing specific criteria
Direct Specialty Routing
Ensure your oncologist identifies the submission as an urgent oncology prior authorization to route it to specialized reviewers familiar with cancer treatment protocols.
Clinician Corner: When drafting medical necessity letters, reference specific sections of Humana's medical policy and include exact biomarker values, staging details, and treatment response data. This demonstrates clear alignment with coverage criteria and speeds approval.
Common Denial Reasons & Solutions
| Denial Reason | Quick Fix | Required Documentation |
|---|---|---|
| Missing biomarker testing | Submit lab reports | PD-L1, MSI-H, or TMB-H results with reference ranges |
| Wrong line of therapy | Document prior failures | Treatment timeline with progression dates |
| Off-label indication | Provide guideline support | NCCN guidelines or FDA label citations |
| Inadequate staging | Submit recent scans | Complete staging workup within 3 months |
| Step therapy not met | Request exception | Contraindication or prior failure documentation |
