Set Your Goal: Understanding UnitedHealthcare's Requirements

Getting Increlex (mecasermin) covered by UnitedHealthcare requires meeting strict clinical criteria for severe primary IGF-1 deficiency. Your partnership with your pediatric endocrinologist is essential—they'll need to document that standard growth hormone therapy won't work for your child's specific condition.

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Prior Authorization Required through provider portal UHC Provider Portal
Height ≤ −3.0 standard deviation scores Growth charts, pediatric records
IGF-1 Levels ≤ −3.0 SDS or <2.5th percentile Recent lab results
GH Testing Normal or elevated on stimulation tests Endocrine testing records
Specialty Pharmacy Dispensed through designated network Accredo, CVS Specialty, others
Annual Renewal Required with growth velocity documentation Provider renewal process

UnitedHealthcare's OptumRx requires prior authorization for Increlex, and the medication must be dispensed through their specialty pharmacy network—not through OptumRx directly due to manufacturer restrictions.

Note: UnitedHealthcare has increased specialty medication prior authorization requirements by approximately 15% for 2025, making thorough documentation more critical than ever.

Visit Preparation: Building Your Clinical Case

Before your appointment, compile a comprehensive timeline of your child's growth challenges and treatment history. This preparation will help your endocrinologist build the strongest possible case for medical necessity.

Symptom and Growth Timeline

Document these key elements:

  • Growth measurements from birth to present (bring growth charts if available)
  • Growth velocity over the past 2-3 years
  • Developmental milestones and any delays
  • Previous growth hormone therapy (if tried) and response
  • Other treatments attempted and their outcomes

Treatment History Summary

Create a clear record of:

  • Medications tried with dates, doses, and duration
  • Reasons for discontinuation (ineffective, side effects, contraindications)
  • Laboratory monitoring results during previous treatments
  • Specialist consultations and their recommendations

Functional Impact Notes

Prepare to discuss:

  • How short stature affects your child's daily activities
  • Social and emotional impacts
  • Educational accommodations needed
  • Quality of life concerns for your family

Evidence Kit: Essential Documentation

Your endocrinologist will need comprehensive clinical evidence to support the prior authorization request. Gather these documents before your visit:

Required Laboratory Results

  • Recent IGF-1 levels (within 6 months, showing ≤ −3.0 SDS)
  • IGF-BP3 levels for additional confirmation
  • Growth hormone stimulation test results (demonstrating normal/elevated GH)
  • Comprehensive metabolic panel to rule out secondary causes
  • Thyroid function tests (TSH, T4)
  • Complete blood count and inflammatory markers

Imaging and Growth Documentation

  • Bone age X-ray (left hand and wrist)
  • Growth charts plotted over time
  • MRI of pituitary/hypothalamus (if performed to rule out GH deficiency)

Clinical Records

  • Previous endocrinology consultation notes
  • Growth hormone therapy records (if applicable)
  • Genetic testing results (if performed)
  • Documentation of secondary cause exclusion

Medical Necessity Letter Structure

Your pediatric endocrinologist should structure the medical necessity letter to address UnitedHealthcare's specific coverage criteria. Here's what should be included:

Essential Components

Patient Information Section:

  • Patient demographics and insurance details
  • Primary diagnosis with ICD-10 code (E34.3 for short stature due to IGF-1 deficiency)
  • Current height and weight with percentiles

Clinical Rationale:

  • Documented height ≤ −3.0 SDS with supporting measurements
  • IGF-1 levels ≤ −3.0 SDS with lab dates and reference ranges
  • Normal or elevated GH stimulation test results
  • Exclusion of secondary causes (malnutrition, chronic illness, hypothyroidism)

Treatment Justification:

  • Why growth hormone therapy is inappropriate or has failed
  • Expected benefits of Increlex therapy
  • Monitoring plan for hypoglycemia and other side effects
  • Treatment goals and timeline

Supporting References:

  • FDA labeling for Increlex
  • Pediatric endocrinology society guidelines
  • Peer-reviewed studies on severe primary IGF-1 deficiency treatment

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to identify the specific denial basis and draft point-by-point rebuttals aligned with each plan's requirements.

Peer-to-Peer Review Support

If the initial prior authorization is denied, UnitedHealthcare offers peer-to-peer review where your endocrinologist can speak directly with a UnitedHealthcare medical director. This conversation often determines approval success.

Preparing Your Provider

Offer to help your endocrinologist prepare by providing:

  • Concise patient summary (2-3 sentences on diagnosis and current status)
  • Treatment rationale explaining why Increlex is medically necessary
  • Alternative therapy considerations and why they're inappropriate
  • Clinical guideline references supporting the treatment decision

Scheduling and Availability

  • Timeline: UnitedHealthcare must make the peer clinical reviewer available within one business day of an adverse determination
  • Provider preparation: Your endocrinologist should have your complete file ready
  • Key talking points: FDA-approved indications, safety monitoring plan, expected outcomes

Maximizing Success

Successful peer-to-peer reviews typically emphasize:

  • Clear differentiation between GH deficiency and primary IGF-1 deficiency
  • Documentation that GH therapy is ineffective for this specific condition
  • Comprehensive safety monitoring plan for hypoglycemia risk
  • Alignment with established pediatric endocrinology treatment standards

After Your Visit: Next Steps

Once your endocrinologist submits the prior authorization, stay organized and proactive about tracking the process.

What to Save

  • Copy of the prior authorization request and all supporting documents
  • Confirmation number or reference number from submission
  • Timeline expectations provided by your provider's office
  • Contact information for the specialty pharmacy coordinator

Portal Communication

  • Set up online access to UnitedHealthcare's member portal
  • Check authorization status regularly (typically updated within 1-2 business days)
  • Save all correspondence including emails and portal messages
  • Screenshot important updates for your records

Coordination with Specialty Pharmacy

  • Enroll with designated specialty pharmacy (Accredo, CVS Specialty, or Walgreens Specialty)
  • Provide insurance information and prior authorization details
  • Confirm delivery logistics and storage requirements
  • Review hypoglycemia monitoring supplies and glucose meter setup

Respectful Persistence: Following Up Effectively

Maintaining appropriate follow-up without overwhelming your healthcare team requires strategic timing and clear communication.

Follow-Up Schedule

  • Week 1: Confirm submission and get reference number
  • Week 2: Check status through member portal
  • Week 3: Contact provider's office if no update
  • Week 4: Escalate if still pending (UnitedHealthcare standard timeline is 15 business days)

Effective Communication Scripts

For Provider Office: "Hi, I'm checking on the status of my child's Increlex prior authorization submitted on [date]. The reference number is [number]. Could you please check if UnitedHealthcare has requested any additional information?"

For UnitedHealthcare: "I'm calling about prior authorization reference [number] for my child's Increlex prescription. It's been [timeframe] since submission. Can you tell me the current status and if any additional documentation is needed?"

When to Escalate Politely

  • Beyond standard timeline without communication
  • Requests for information already provided
  • Unclear denial reasons that need clarification
  • Urgent medical need requiring expedited review

California Appeals Process

California offers robust patient protections through the Department of Managed Health Care (DMHC), with high success rates for overturning insurance denials.

Internal Appeals with UnitedHealthcare

Timeline: 180 days from denial date Process: Submit through member portal or mail Required documents:

  • Original denial letter
  • Updated medical necessity letter
  • Any new clinical evidence
  • Provider attestation of medical necessity

California Independent Medical Review (IMR)

If UnitedHealthcare upholds the denial after internal appeal, California's IMR process provides independent review with binding decisions.

Eligibility: Available after exhausting internal appeals for medical necessity denials Timeline:

  • Standard IMR: 45 days for decision
  • Expedited IMR: 72 hours for urgent cases Success rates: 60-80% of denials are overturned through California's IMR process Cost: No fee to patients

How to Request IMR:

  1. File online at healthhelp.ca.gov
  2. Call DMHC Help Center: 888-466-2219
  3. Submit required documents: denial letter, medical records, provider support
From Our Advocates: We've seen families succeed with California IMR by focusing their case on the clear diagnostic criteria for severe primary IGF-1 deficiency. The independent medical reviewers understand that this isn't typical short stature—it's a specific condition where growth hormone won't work. Strong lab documentation and a pediatric endocrinologist's detailed explanation of why Increlex is the only appropriate treatment typically leads to approval.

FAQ

How long does UnitedHealthcare prior authorization take for Increlex in California? Standard timeline is 15 business days, but complex cases may take longer. Expedited review is available for urgent medical situations and typically resolves within 72 hours.

What if Increlex is non-formulary on my UnitedHealthcare plan? Non-formulary medications can still be covered through medical necessity exceptions. Your endocrinologist must demonstrate that formulary alternatives are inappropriate for severe primary IGF-1 deficiency.

Can I request expedited appeal if my child needs Increlex urgently? Yes, UnitedHealthcare offers expedited appeals for urgent situations. Your provider must document that delays could significantly impact your child's health or development.

Does step therapy apply to Increlex coverage? Step therapy typically requires trying growth hormone first, but exceptions are available when GH therapy is contraindicated or inappropriate for primary IGF-1 deficiency.

What happens if UnitedHealthcare denies the appeal? California residents can request Independent Medical Review through DMHC, which has a 60-80% success rate for overturning denials. The IMR decision is binding on UnitedHealthcare.

How often does Increlex coverage need renewal? UnitedHealthcare requires annual prior authorization renewal with documentation of continued growth velocity (≥2 cm/year), updated IGF-1 levels, and confirmation that final adult height hasn't been reached.

Can I switch to a different UnitedHealthcare plan for better Increlex coverage? During open enrollment, you can compare formulary coverage, but Increlex typically requires prior authorization across all UnitedHealthcare plans. Focus on plans with lower specialty medication cost-sharing.

What if my child experiences side effects during treatment? Report side effects immediately to your endocrinologist. Hypoglycemia is the most serious risk and requires careful monitoring. Side effects don't automatically disqualify coverage but may require dosing adjustments.
