How to Get Ozempic and Mounjaro Covered by Humana in California: Prior Authorization Forms, Appeal Deadlines, and State Protections

Answer Box: Getting Ozempic/Mounjaro Covered by Humana in California

Humana Medicare Advantage plans in California typically require prior authorization for Ozempic (semaglutide) and Mounjaro (tirzepatide), with both drugs listed as Tier 3-5 specialty medications. Most denials stem from step therapy requirements or lack of diabetes diagnosis documentation. Your fastest path to approval:

  1. Check your 2024 formulary at humana.com/pharmacy/medicare-drug-list
  2. Submit prior authorization with A1c levels, prior medication failures, and diabetes diagnosis
  3. If denied, file redetermination within 65 days using Humana's official appeal form

California residents have additional protections through Independent Medical Review (IMR) if internal appeals fail. Start today by calling the number on your Humana ID card to confirm PA requirements for your specific plan.

Why California State Rules Matter

California's robust healthcare regulations provide additional protections beyond federal Medicare requirements. While Humana operates under Medicare Part D rules, California's Department of Managed Health Care (DMHC) oversees most HMO and PPO plans, offering Independent Medical Review (IMR) for denials deemed not medically necessary.

Key California advantages:

  • No-cost IMR appeals with 68% approval rates for medical necessity disputes
  • Step therapy override protections (expanding to insulin and diabetes medications in 2026)
  • Continuity of care rights during formulary changes or provider network updates
  • Expedited review timelines for urgent medication needs
Note: Self-funded employer plans (ERISA) may have limited state law protections, but Medicare Advantage plans like Humana are subject to both federal and California regulations.

Humana's Prior Authorization Requirements

Coverage Status and Formulary Placement

Both Ozempic and Mounjaro require prior authorization on most Humana Medicare Advantage plans in California. Check your specific plan's 2024 formulary using Humana's drug list tool, as tier placement affects your copay:

Drug Typical Tier Monthly Cost Range PA Required
Ozempic (semaglutide) Tier 3-4 $47-$150+ after deductible Yes
Mounjaro (tirzepatide) Tier 4-5 $100-$400+ after deductible Yes

Step Therapy Protections in California

Current Rules (2024)

California's step therapy laws currently allow insurers to require trial of preferred medications before covering newer agents like semaglutide or tirzepatide. However, physicians can request step therapy exceptions when:

  • Patient has contraindications to preferred drugs
  • Previous trials resulted in inadequate response or adverse effects
  • Delay would cause significant clinical deterioration

Upcoming Changes (January 2026)

SB 40 will prohibit step therapy for:

  • Insulin products
  • Prescriptive diabetes medications
  • Glucagon

Note: Semaglutide and tirzepatide may still be subject to step therapy requirements, but override provisions will be strengthened.

Documentation for Step Therapy Override

Essential elements for your physician's request:

  • Prior medications tried: drug names, doses, duration, specific reasons for discontinuation
  • Clinical rationale: why the requested medication is medically necessary
  • Patient-specific factors: comorbidities, contraindications, treatment response patterns
  • Timeline urgency: if applicable, why delay poses clinical risks

Continuity of Care During Plan Changes

When COC Protections Apply

California law mandates continuity of care protections for members with ongoing specialty medication treatments during:

  • Provider network terminations
  • Plan formulary changes
  • Transition between Medicare Advantage plans

Eligibility criteria:

  • Serious or complex medical conditions requiring ongoing treatment
  • Current therapy showing clinical stability or improvement
  • Provider agreement to continue care under previous terms

How to Request COC

  1. Contact Humana within 30 days of receiving termination or formulary change notice
  2. Submit written COC request with medical records documenting treatment necessity
  3. Obtain provider agreement to continue care
  4. Coverage duration: Up to 90 days for transitions, 12 months for ongoing therapy

For formulary changes affecting Ozempic or Mounjaro:

  • Document current treatment stability (A1c improvements, weight loss progress)
  • Note any previous failures with alternative GLP-1 agonists
  • Include prescriber's clinical assessment of switching risks

Practical Scripts and Documentation

Phone Script for Humana Member Services

"Hi, I'm calling about prior authorization for [Ozempic/Mounjaro] for my Type 2 diabetes. My member ID is [number]. Can you tell me the specific PA criteria for my plan and provide the submission form? I also need to know if step therapy is required and what documentation my doctor should include."

Medical Necessity Letter Checklist

For clinicians preparing PA requests:

Patient demographics and member ID ✓ Diagnosis with specific ICD-10 codes ✓ Current A1c and BMI with dates ✓ Prior medications tried with doses, duration, and reasons for discontinuation ✓ Clinical rationale citing ADA/AACE guidelines ✓ Contraindications to formulary alternatives ✓ Treatment goals and monitoring plan ✓ Prescriber credentials and contact information

Peer-to-Peer Review Request

"I'm requesting a peer-to-peer review for [patient name] regarding the denial of [medication]. This patient has documented treatment failures with [list medications] and meets clinical criteria per [cite specific guidelines]. When can we schedule the review?"

Understanding ERISA Plan Limitations

Important distinction: While this guide focuses on Medicare Advantage plans subject to California regulations, employer-sponsored plans governed by ERISA have different appeal rights:

  • Limited state law protections (federal law preempts many state requirements)
  • Different appeal timelines and procedures
  • No access to California IMR for ERISA plans

To identify plan type:

  • Check your Summary Plan Description (SPD)
  • Look for ERISA language in plan documents
  • Ask HR or member services directly

Educational note: Always verify your specific plan's regulatory status, as appeal rights vary significantly.
