Medical Necessity Criteria

Required Documentation

Clinical Evidence Must Include:

  • ICD-10 diagnosis code for hypoparathyroidism
  • Documented inadequate control on calcium and vitamin D alone
  • Serum calcium levels and symptoms
  • Contraindications to standard therapy (if applicable)

Step Therapy Requirements

Aetna typically requires documentation of:

  1. Adequate trial of oral calcium supplements
  2. Adequate trial of calcitriol or other active vitamin D analogs
  3. Failure criteria: Persistent hypocalcemia, intolerable side effects, or contraindications
Clinician Corner: Include specific dosages, duration of trials, and quantified outcomes (lab values, symptom severity) in your medical necessity letter. Reference FDA labeling and endocrine society guidelines where applicable.

Patient Costs and Savings

Typical Cost Structure

  • Tier placement: Specialty tier (highest copay/coinsurance)
  • Site of care: Must use CVS Specialty Pharmacy
  • Copay assistance: Check manufacturer programs (while supplies last)

Savings Options

  • Takeda OnePath patient support: 1-866-888-0660
  • State pharmaceutical assistance programs
  • Foundation grants for rare disease medications

Denials and Appeals

Common Denial Reasons & Solutions

Denial Reason How to Overturn Required Documentation
Non-formulary Request formulary exception Medical necessity letter, failed alternatives
Step therapy not met Document prior failures Detailed trial records with outcomes
Experimental/investigational Cite FDA approval FDA labeling, clinical guidelines
Not medically necessary Strengthen clinical rationale Lab results, symptom documentation

Aetna Internal Appeals Process

Level 1 Appeal

  • Deadline: 180 days from denial (commercial), 60 days (Medicare)
  • Method: Aetna provider portal or written request
  • Timeline: 30 days for standard, 72 hours for expedited

Level 2 Appeal

  • Available if Level 1 denied
  • Same deadlines and submission methods
  • Often includes peer-to-peer review option
Tip: Request a peer-to-peer review with an endocrinologist familiar with hypoparathyroidism. This often resolves denials faster than written appeals alone.

North Carolina External Review

If Aetna's internal appeals are exhausted, North Carolina residents can use the state's external review program.

Smart NC External Review Process

Eligibility Requirements:

  • State-regulated plan (not self-funded ERISA plans)
  • Completed Aetna's internal appeal process
  • Denial based on medical necessity or experimental treatment determination

How to Apply:

  1. Contact Smart NC: 855-408-1212 for free assistance

The North Carolina Department of Insurance administers this program with a strong track record of overturning specialty drug denials when supported by comprehensive clinical evidence.

Alternative Therapies

Given Natpara's discontinuation, focus has shifted to alternative treatments:

FDA-Approved Alternatives

  • TransCon PTH (palopegteriparatide): New PTH analog approved in 2023
  • High-dose calcium with active vitamin D analogs
  • Thiazide diuretics to reduce calcium excretion

Coverage Strategy for Alternatives

When requesting coverage for new PTH therapies:

  1. Reference Natpara's discontinuation in your request
  2. Document inadequate control with calcium/vitamin D alone
  3. Cite clinical instability risks
  4. Request formulary exception if not covered
