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.
