Understanding Tegsedi Coverage Requirements

Tegsedi (inotersen) is a specialty medication that requires prior authorization for all Humana Medicare Advantage plans. The drug targets hereditary transthyretin-mediated amyloidosis (hATTR) polyneuropathy, a rare genetic condition affecting the nervous system.

Coverage at a Glance

Requirement What It Means Documentation Needed
Prior Authorization Mandatory approval before coverage Completed PA form with clinical rationale
REMS Program Risk mitigation for safety monitoring Patient, prescriber, and pharmacy certification
Genetic Testing Confirmed TTR gene mutation Lab report showing specific mutation
Specialist Prescription Neurologist or geneticist required Provider credentials and specialty verification
Baseline Labs Safety monitoring requirements Platelet count ≥100k, eGFR ≥45

The medication carries significant costs, typically placing it in specialty tier categories. Humana's CenterWell Specialty Pharmacy handles distribution for most specialty medications, providing clinical support and coordination.
