What Affects Approval Timing

Several factors influence how quickly Humana processes your Darzalex / Darzalex Faspro prior authorization:

Benefit Classification: Since daratumumab is typically covered under the medical benefit (Part B) rather than pharmacy benefit, it follows CMS medical PA timelines of 7 days standard or 72 hours expedited.

Documentation Completeness: Humana's new electronic PA system aims for 1 business day decisions on 95% of complete electronic requests by 2026. Incomplete submissions can add 1-7 days for additional information requests.

Clinical Complexity: Straightforward cases (newly diagnosed multiple myeloma, NCCN-guideline regimens) process faster than off-label uses or complex prior therapy histories requiring clinical review.

Pre-Submission Preparation (0-2 Days)

Checklist: What to Gather Before You Start

Patient Information

  • Humana member ID and group number
  • Current Illinois address and contact information
  • Primary care physician and oncologist details

Clinical Documentation

  • Pathology report confirming multiple myeloma diagnosis
  • Staging information (ISS, R-ISS if available)
  • Complete prior therapy history with dates, responses, and reasons for discontinuation
  • Recent labs (CBC, comprehensive metabolic panel, free light chains)
  • Current weight and BSA for dosing calculations

Insurance Verification

  • Call the number on your Humana card to confirm:
    • Whether Darzalex requires PA for your specific plan
    • Your current deductible and coinsurance
    • In-network infusion centers in your area
Tip: Ask your oncology practice's financial counselor to handle insurance verification. They often have direct provider lines that can expedite benefit confirmation.

Submission to Initial Review (1-7 Days)

Your oncologist submits the PA request through Humana's provider portal or designated electronic system. The submission must include:

Required Clinical Information

  1. Diagnosis: ICD-10 code (typically C90.0- for multiple myeloma) with supporting pathology
  2. Treatment Plan: Specific regimen (e.g., D-Rd, D-VMP) with dosing schedule
  3. Prior Therapies: Documentation of previous treatments and outcomes
  4. Medical Necessity: Letter explaining why Darzalex is appropriate for this patient's case

Administrative Details

  • HCPCS codes: J9145 (IV Darzalex) or J9144 (Darzalex Faspro)
  • Planned site of administration
  • Prescriber NPI and specialty certification

Under CMS rules effective January 2026, Humana must decide within 7 calendar days for standard requests or 72 hours for expedited cases where delay could jeopardize health.

Additional Information Requests (1-7 Days)

If Humana needs more information, they'll contact your provider within 24-48 hours of submission. Common requests include:

  • Missing prior therapy documentation: Specific dates and outcomes of previous treatments
  • Dosing clarification: Weight-based calculations or administration schedule details
  • Site of care justification: Why hospital outpatient vs. office-based infusion is necessary

How to Respond Quickly

  • Providers should respond within 24 hours to avoid delays
  • Submit additional documents through the same electronic portal
  • Include a cover letter summarizing what was provided

Decision Window and Outcomes

Humana will issue one of three decisions:

Approval: You'll receive an authorization number valid for a specific time period (typically 6 months for ongoing therapy). The approval letter will specify:

  • Authorized HCPCS codes and quantities
  • Approved sites of administration
  • Any special requirements (premedications, monitoring)

Denial: A written notice explaining the reason for denial and your appeal rights. Common denial reasons include insufficient documentation, step therapy requirements, or "not medically necessary" determinations.

Partial Approval: Coverage for a limited quantity or different formulation (e.g., IV instead of subcutaneous, or fewer cycles).

If Denied: Appeals Timeline

Illinois patients have strong appeal rights with specific timelines:

Internal Appeal (First Level)

  • Deadline: 65 days from denial notice date
  • Timeline: Humana has 30 days for pre-service appeals, 60 days for post-service
  • Expedited: 72 hours if delay could seriously jeopardize health
  • How to File: Humana member portal or written request

Illinois External Review (Second Level)

  • Deadline: 30 days after final internal denial (shorter than most states)
  • Process: Illinois Department of Insurance assigns independent physician reviewer
  • Timeline: Decision within 5 business days of receiving records
  • Cost: Free to patients
  • Binding: If overturned, Humana must cover the treatment
Note: Illinois' 30-day external review deadline is stricter than the federal 4-month window. Act promptly after receiving a final denial.

  • Any changes to dosing or administration schedule
  • Updated weight and BSA calculations

Streamlined Renewal Process

FAQ

How long does Humana prior authorization take for Darzalex in Illinois? Standard requests: up to 7 days. Expedited requests (when delay risks health): 72 hours. Electronic submissions through Humana's provider portal are fastest.

What if Darzalex is non-formulary on my plan? Request a formulary exception with medical necessity documentation. Your oncologist must demonstrate why covered alternatives are inappropriate.

Can I request an expedited appeal in Illinois? Yes, if delaying treatment could seriously jeopardize your health. Your doctor must certify the urgency, and Humana must decide within 72 hours.

Does Illinois step therapy law help with Darzalex appeals? Illinois doesn't have specific step therapy override laws like some states, but physicians can provide attestations about prior therapy failures to support medical necessity.

What happens if I start treatment before approval? You may be responsible for full costs. However, if you have a medical emergency, Humana may provide retroactive authorization with proper documentation.

How do I find in-network infusion centers in Illinois? Use Humana's provider directory online or call member services. Your oncology practice may also have a preferred network of contracted infusion centers.
