How to Get Natpara (Parathyroid Hormone) Covered by Cigna in North Carolina: Complete 2025 Appeals Guide

Answer Box

Getting Natpara (parathyroid hormone) covered by Cigna in North Carolina requires understanding that Takeda discontinued manufacturing in December 2024. New starts are typically denied due to lack of commercial supply. For existing patients, you'll need prior authorization showing chronic hypoparathyroidism, failed conventional therapy (calcium + active vitamin D), and enrollment in the Special Use Program. If denied, North Carolina's Smart NC external review overturns approximately 50% of specialty drug denials. First step: Contact your endocrinologist to document inadequate control on maximized conventional therapy and request a detailed medical necessity letter citing current ESE guidelines.

Read the Denial: Understanding Cigna's Position

When Cigna denies Natpara coverage, the reason typically falls into one of these categories:

Most Common Denial Reasons (2025)

Denial Reason What It Means Next Steps
Drug discontinued No commercial supply available Document existing use + Special Use Program enrollment
Insufficient step therapy Lack of documented calcium/vitamin D failures Compile detailed treatment history with doses/dates
Missing lab documentation No recent PTH, calcium, or vitamin D levels Order complete hypoparathyroidism lab panel
Non-formulary status Not on Cigna's preferred drug list Request formulary exception with medical necessity
Prescriber requirements Not prescribed by/with endocrinologist Obtain endocrinology consultation and letter
Critical: Natpara's manufacturing ended December 31, 2024. The Special Use Program continues only for existing patients through December 2025.
