Understanding the Natpara Situation

Natpara (parathyroid hormone) faces unprecedented coverage challenges in 2025. Takeda discontinued manufacturing globally, with all U.S. shipments through the Special Use Program ending December 31, 2025.

Key Facts:

  • Manufacturing ceased at end of 2024 due to unresolved particle formation issues
  • Only existing Special Use Program patients can receive shipments through 2025
  • New patient requests are typically denied due to supply unavailability
  • Alternative parathyroid hormone treatments are now available

This means your approach depends entirely on whether you're currently receiving Natpara or seeking to start treatment.

Blue Cross Blue Shield Prior Authorization Requirements

BCBS plans across Washington require prior authorization for Natpara when available. Requirements vary by specific plan (Premera Blue Cross, Regence BlueShield, etc.), but common criteria include:

Coverage Requirements Table

Requirement What It Means Where to Find It
Prior Authorization Required for all requests Plan formulary or member portal
Specialist Prescription Must be prescribed by endocrinologist PA form requirements
Failed Conventional Therapy Documentation of calcium/vitamin D inadequacy Medical records
Confirmed Diagnosis Hypoparathyroidism with appropriate ICD-10 codes Provider documentation
Step Therapy Try alternatives first Plan's step therapy protocols
Note: Due to Natpara's discontinuation, most BCBS plans have updated policies to deny new starts while supporting existing patients through transition planning.

Step-by-Step: Fastest Path to Coverage

For Existing Natpara Patients:

  1. Contact your endocrinologist immediately to discuss transition planning before December 31, 2025
  2. Verify current coverage status through your BCBS member portal or customer service
  3. Document your current treatment response and any complications from conventional therapy
  4. Coordinate with your provider to explore alternative parathyroid hormone treatments
  5. Submit insurance authorization requests for transition medications with comprehensive documentation

For New Patients Seeking Treatment:

  1. Confirm hypoparathyroidism diagnosis with your endocrinologist
  2. Document failed conventional therapy (calcium supplements, active vitamin D)
  3. Research alternative treatments like palopegteriparatide (newly approved PTH analogue)
  4. Submit prior authorization for available alternatives with medical necessity justification
  5. Prepare for potential appeals with robust clinical documentation

Common Denial Reasons and How to Fix Them

Denial Reason How to Overturn Required Documentation
"Drug discontinued/not available" Request coverage for alternatives Specialist letter recommending alternative PTH therapy
"Not medically necessary" Provide evidence of failed conventional therapy Lab results, hospitalization records, symptom documentation
"Experimental/investigational" Cite FDA approval and clinical guidelines FDA labeling, Endocrine Society guidelines
"Step therapy not completed" Document contraindications or failures Prior therapy records, adverse event documentation
"Non-formulary" Request formulary exception Medical necessity letter with clinical justification

Appeals Process for BCBS in Washington

Washington provides strong consumer protections for insurance appeals. Here's your roadmap:

Internal Appeals (Required First Step)

Timeline: 180 days from denial date to file Process:

  1. Call the number on your member ID card to request appeal forms
  2. Submit written appeal with supporting documentation
  3. Request peer-to-peer review with medical director if needed
  4. Await decision (typically 15 business days for standard, 72 hours for urgent)

Required Documentation:

  • Original denial letter
  • Medical necessity letter from prescribing physician
  • Clinical notes and lab results
  • Evidence of failed alternative therapies
  • Relevant clinical guidelines or FDA labeling

Medical Necessity Documentation

Clinician Corner: Medical Necessity Letter Checklist

Your endocrinologist's letter should include:

Essential Elements:

  • Confirmed diagnosis: Hypoparathyroidism with ICD-10 codes (E20.0-E20.9)
  • Failed conventional therapy: Specific calcium and vitamin D regimens tried, doses, duration, and reasons for inadequacy
  • Clinical complications: Hospitalizations, severe symptoms, quality of life impacts
  • Treatment goals: Target calcium levels, symptom management objectives
  • Monitoring plan: Laboratory follow-up schedule and safety monitoring

Supporting Evidence:

  • Current treatment guidelines recommend PTH therapy for patients inadequately controlled on conventional treatment
  • FDA labeling for available PTH analogues
  • Documentation of contraindications to high-dose calcium or vitamin D therapy
From our advocates: We've seen the strongest approvals when providers include specific calcium and phosphorus levels over time, document emergency department visits for hypocalcemia, and clearly explain why conventional therapy doses can't be increased further due to side effects or complications.

Washington State External Review Process

If your internal appeals fail, Washington offers robust external review through Independent Review Organizations (IROs).

How to Request External Review:

  1. File through your BCBS plan after exhausting internal appeals
  2. Timeline: Submit within 180 days of final internal denial
  3. Cost: Free to you
  4. Process: Your insurer assigns case to certified IRO within 3 business days
  5. Your input: You have 5 business days to submit additional information to the IRO
  6. Decision: IRO issues binding decision within 30 days (72 hours for expedited cases)

Contact for Help:

IRO Review Criteria:

  • Medical necessity based on current standards of care
  • Appropriateness of treatment for your specific condition
  • Whether plan's denial criteria are reasonable and evidence-based

Alternative Treatment Options

  • Conventional therapy: Calcium supplements plus active vitamin D (calcitriol)

Coverage Strategy:

  1. Document inadequacy of conventional therapy thoroughly
  2. Request prior authorization for palopegteriparatide with comprehensive medical necessity justification
  3. Emphasize compliance with current treatment guidelines recommending PTH therapy for inadequately controlled patients
