Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
Insufficient biochemical evidence Submit complete lab panel with trending results UFC levels, IGF-1, glucose monitoring over time
No prior SSA trial (acromegaly) Document octreotide/lanreotide failure or intolerance Pharmacy records, adverse event notes, efficacy data
Non-specialist prescriber Transfer care or get co-signature Endocrinologist consultation/co-management
Dosing outside label Justify with clinical rationale Weight-based calculations, prior dose escalation attempts
Alternative therapy available Prove contraindications or failures Allergy documentation, surgical contraindications
From Our Advocates: We've seen cases where patients were initially denied for "insufficient documentation" but succeeded on appeal by including trending lab values over 3-6 months rather than single-point measurements. The key is demonstrating disease progression despite standard interventions, not just meeting diagnostic thresholds.

Medical Necessity Letter Essentials

Clinician Corner: Letter of Medical Necessity Checklist

Your endocrinologist's letter should include these critical elements:

Patient-Specific Clinical Information:

  • Clear ICD-10 diagnosis (E24.0 for Cushing's disease, E22.0 for acromegaly)
  • Symptom timeline and functional impairment
  • Surgical history and outcomes
  • Complete medication trial history with specific dates, doses, and outcomes

Biochemical Evidence:

  • Baseline and trending laboratory values
  • UFC levels for Cushing's disease
  • GH and IGF-1 levels for acromegaly
  • Glucose tolerance and diabetes management status

Medical Necessity Justification:

  • Why surgery is not an option or was not curative
  • Specific reasons other therapies failed or are contraindicated
  • Expected clinical outcomes with Signifor LAR
  • Monitoring plan and safety considerations

Supporting Citations:

  • FDA prescribing information
  • Endocrine Society clinical practice guidelines
  • Peer-reviewed studies demonstrating efficacy in similar patient populations

When to Request Peer-to-Peer Review

If your initial prior authorization is denied, requesting a peer-to-peer call can be more effective than written appeals alone. Here's when and how:

Best Timing: Within 24-48 hours of denial notice Who Participates: Your prescribing endocrinologist and Humana's medical director Preparation: Have denial letter, patient chart, and supporting studies readily available Key Talking Points:

  • Specific contraindications to formulary alternatives
  • Documented treatment failures with exact dates and outcomes
  • Unique patient factors requiring this specific therapy

Scheduling Script for Clinic Staff: "I'm calling to request a peer-to-peer review for [patient name] regarding the denial for Signifor LAR. Dr. [Name] is available [specific time blocks] and has additional clinical information that wasn't included in the original submission."

Frequently Asked Questions

How long does Humana prior authorization take for Signifor LAR in Illinois? Standard decisions take up to 30 days, but expedited reviews (when urgent medical need is documented) must be completed within 72 hours. Humana has committed to processing 95% of electronic PA requests within one business day by 2026.

What if Signifor LAR is not on Humana's formulary? You can request a formulary exception with supporting medical documentation. The process is similar to prior authorization but requires proving that formulary alternatives would be less effective or cause adverse effects.

Can I appeal if I live in Illinois but have coverage from another state? Your appeal rights depend on where your insurance policy is issued, not where you live. However, if you have Humana Medicare Advantage, federal Medicare appeal rights apply regardless of state.

Does step therapy apply if I've tried similar medications outside Illinois? Yes, documented treatment failures from any location count toward step therapy requirements, provided you have adequate medical records and pharmacy history.

What happens if my external review is denied? External review decisions are final for that specific treatment request. However, you may be able to submit a new request if your clinical condition changes or new evidence becomes available.

How do I know if my prescriber is considered a "specialist" by Humana? Endocrinologists typically qualify as specialists for hormone-related conditions. Your insurance directory or Humana's provider portal can confirm specialist status.

Can I get expedited review if I'm currently on Signifor LAR? Yes, if you're facing treatment interruption that could jeopardize your health, you can request expedited review with physician documentation of medical urgency.
