Answer Box: Getting Natpara Approved by UnitedHealthcare in North Carolina

Important Update: Takeda permanently discontinued Natpara manufacturing in December 2024, with the Special Use Program ending December 31, 2025. New patient approvals are extremely unlikely due to lack of commercial supply.

For existing patients: UnitedHealthcare typically requires 1-15 business days for prior authorization decisions through OptumRx. You must document failure of high-dose calcium plus active vitamin D therapy and have an endocrinologist or nephrologist prescribe the medication.

First step today: Call UnitedHealthcare member services to confirm your plan type and whether you're eligible for North Carolina's external review process if denied.

Before diving into approval timelines, it's crucial to understand the current reality of Natpara access. Takeda permanently ended global manufacturing at the end of 2024, and the U.S. Special Use Program will close on December 31, 2025.

What this means for UnitedHealthcare coverage:


What Affects UnitedHealthcare Approval Timing

Several factors influence how quickly UnitedHealthcare processes Natpara prior authorizations:

Benefit Type and Plan Structure

  • Commercial plans with OptumRx: Standard 1-15 business day timeline
  • Medicare Advantage: Similar timeline but may have additional documentation requirements
  • Self-funded employer plans: May follow different procedures than state-regulated plans

Complexity of Clinical Criteria

UnitedHealthcare requires documentation of:

Completeness of Initial Documentation

Incomplete submissions can add 1-7 days for additional information requests. The more comprehensive your initial submission, the faster the decision.


Pre-Submission Preparation (0-2 Days)

Essential Documentation Checklist

Before submitting your prior authorization, gather:

Clinical Records:

  • Confirmed hypoparathyroidism diagnosis with ICD-10 code E20.0
  • Recent lab results (serum calcium, phosphate, PTH, 25-hydroxyvitamin D)
  • Documentation of calcium and vitamin D therapy trials with doses and outcomes
  • Records of any adverse effects or contraindications to standard therapy

Provider Requirements:

  • Prescription from an endocrinologist or nephrologist
  • Letter of medical necessity addressing UnitedHealthcare's specific criteria
  • Treatment plan including monitoring schedule

Insurance Information:

  • UnitedHealthcare member ID and group number
  • Confirmation of pharmacy benefit manager (typically OptumRx)
  • Verification of plan type (fully insured vs. self-funded)

Verify Your Plan Type

Call the number on your UnitedHealthcare ID card and ask:

  • "Is Natpara covered under my pharmacy or medical benefit?"
  • "Is OptumRx handling prior authorization for specialty medications?"
  • "Is my plan regulated by North Carolina or self-funded?"

This information determines your appeals rights and external review options.


Submission to Initial Review (1-15 Days)

How to Submit

Prior authorization requests must be submitted through the UnitedHealthcare Provider Portal or by calling 866-889-8054.

OptumRx Review Process

For most UnitedHealthcare plans, OptumRx manages pharmacy prior authorizations using these timelines:

  • Standard review: Up to 15 business days from receipt of complete request
  • Expedited/urgent review: 72 hours when delay may seriously jeopardize health

What Reviewers Check First

  1. Step therapy compliance: Evidence of calcium and vitamin D trial or contraindication
  2. Specialist prescriber: Confirmation of endocrinologist or nephrologist involvement
  3. Clinical necessity: Lab values and symptom documentation supporting need
  4. Special Use Program status: For existing patients, confirmation of SUP enrollment

If Additional Information is Requested

If OptumRx requests additional documentation, respond within 2-3 business days to avoid delays. Common requests include:

  • More detailed treatment history with specific medications and doses
  • Recent specialist consultation notes
  • Laboratory trends showing inadequate control on standard therapy
  • Documentation of side effects or contraindications
Tip: Have your endocrinologist's office designate a staff member to handle prior authorization follow-ups quickly.
