How to Get Turalio (Pexidartinib) Covered by Humana in California: Prior Authorization Guide

Answer Box: Getting Turalio Covered by Humana in California

Turalio (pexidartinib) requires prior authorization from Humana and is typically placed on Tier 5 (specialty tier). To get approved in California:

  1. Complete REMS enrollment - Both prescriber and patient must enroll in the Turalio REMS Program
  2. Submit comprehensive PA request - Include TGCT diagnosis with MRI, surgical assessment, baseline liver function tests
  3. Use Biologics specialty pharmacy - Turalio can only be dispensed through this REMS-certified pharmacy

First step today: Have your prescriber verify their REMS certification and gather your MRI report showing TGCT diagnosis. If denied, California's Independent Medical Review (IMR) process offers strong appeal rights with 50-60% overturn rates.

Plan Types & Coverage Implications

Humana operates several plan types in California, each with different coverage pathways for specialty medications like Turalio:

Medicare Advantage Plans: Most common Humana coverage in California. These plans follow Medicare Part D rules for prescription drugs but may have additional utilization management. Prior authorization is standard for specialty tier medications.

Commercial Plans: Less common but available through employers. These plans are subject to California state insurance regulations and may offer different appeal rights through the Department of Managed Health Care (DMHC).

Note: Medicare Advantage appeals follow federal Medicare procedures, while commercial plans may use California's Independent Medical Review (IMR) process.

Your plan type affects which appeals process you'll use if initially denied. Check your insurance card or member portal to confirm your specific plan structure.


Formulary Status & Tier Placement

Turalio is typically placed on Tier 5 (specialty tier) in Humana Medicare Advantage formularies for 2024. This is the highest cost-sharing tier, reserved for complex, high-cost medications.

Coverage at a Glance

Requirement Status Where to Verify Source
Prior Authorization Required Humana formulary search Humana policy
Formulary Tier Tier 5 (Specialty) Member portal or formulary Plan documents
Quantity Limits Likely applies PA determination Coverage review
Step Therapy May apply Clinical review Medical policy
Specialty Pharmacy Required (Biologics only) REMS program FDA REMS

Alternative medications that insurers may prefer include surgical intervention (when feasible) or off-label use of imatinib or nilotinib, though these have limited evidence for TGCT.


Prior Authorization Requirements

Humana's prior authorization for Turalio focuses on several key criteria:

Medical Necessity Documentation

Diagnosis Requirements:

  • Confirmed tenosynovial giant cell tumor (TGCT) diagnosis
  • MRI imaging demonstrating characteristic features (blooming artifacts, synovial thickening >5mm, hemosiderin deposits)
  • Clear documentation of diffuse-type vs. localized subtype

Clinical Justification:

  • Evidence that surgical options are not feasible or have failed
  • Documentation of severe morbidity or functional limitations
  • Assessment of contraindications to surgery

Safety Requirements:

  • Baseline liver function tests (AST, ALT, bilirubin, alkaline phosphatase, GGT)
  • Confirmation of no active liver disease or biliary tract disease
  • REMS program enrollment completion

Clinician Corner: Medical Necessity Letter Checklist

When preparing your PA request, include:

Problem statement: TGCT diagnosis with ICD-10 code and imaging findings
Prior treatments: Surgical assessment and why surgery isn't appropriate
Clinical rationale: Functional limitations and symptom severity
Guidelines: Reference FDA labeling for approved indication
Safety plan: Baseline labs and monitoring schedule
REMS compliance: Confirmation of prescriber and patient enrollment


REMS Program Enrollment

Turalio is only available through the FDA-mandated REMS program due to serious hepatotoxicity risk. This enrollment is separate from insurance approval but required for coverage.

Enrollment Steps

  1. Prescriber Certification: Your doctor must complete training at TURALIOREMS.com or call 1-833-887-2546
  2. Patient Registration: Complete patient enrollment forms and safety education
  3. Monitoring Plan: Establish schedule for required liver function tests:
    • Weekly LFTs for first 8 weeks
    • Every 2 weeks for next month
    • Every 3 months thereafter
Tip: REMS enrollment typically takes 3-5 business days. Start this process while preparing your PA request to avoid delays.

Humana's REMS Documentation Requirements:

  • Completed prescriber certification
  • Patient enrollment confirmation
  • Baseline liver function test results
  • Monitoring plan documentation

Specialty Pharmacy Network

Critical: Turalio can only be dispensed through Biologics specialty pharmacy - not through Humana's CenterWell Specialty, CVS Specialty, or AccredoHealth.

Appeals Process in California

If your initial PA request is denied, California offers robust appeal rights, though the process depends on your plan type.

Internal Appeals (All Plans)

Timeline: 30 days for standard appeals, 72 hours for expedited
How to File: Humana member portal or member services
Required: Copy of denial letter, additional medical records, prescriber statement

External Review Options

Medicare Advantage Plans:

  • Follow Medicare's federal reconsideration process
  • Independent review entity assigned by CMS
  • Binding decisions when overturned

Commercial Plans:

  • May be eligible for California Independent Medical Review (IMR)
  • File through DMHC for HMOs or CDI for other plans
  • Success rate: 50-60% of specialty drug appeals are overturned
From our advocates: "We've seen patients successfully appeal Turalio denials by emphasizing the functional limitations and including detailed imaging reports. The key is demonstrating that surgery truly isn't an option and that conservative management has failed. Strong appeals often include a peer-reviewed study supporting off-label use when relevant."

California IMR Process

  1. Complete internal appeal with your plan (required first step)
  2. File IMR application within 6 months of final denial
  3. Submit medical records supporting medical necessity
  4. Wait for decision (30 days standard, 7 days expedited)
  5. Plan must comply with favorable IMR decisions (binding)

Contact for Help:

  • DMHC Help Center: 888-466-2219
  • CDI Consumer Hotline: 800-927-4357

When to Escalate

Consider escalating to state regulators if:

  • Humana fails to respond within required timeframes
  • Multiple denials despite complete documentation
  • Plan refuses to honor favorable appeal decisions
  • REMS-related delays affecting patient safety
