Summary
BCBS Mississippi updated their Natroba (spinosad) policy for head lice and scabies treatment, expanding coverage to include scabies treatment for patients 4+ years old with specific quantity limits and prior authorization requirements. The policy now covers head lice treatment for 6+ months old (2 bottles max) and scabies treatment for 4+ years old (4 bottles max), both requiring failure of OTC treatments first.
Action Required
Immediately: Billing team must ensure prior authorization is obtained for all Natroba (spinosad) prescriptions before dispensing. Verify patients meet age requirements (6+ months for head lice, 4+ years for scabies), have documented diagnosis, and have failed OTC treatments (permethrin or pyrethrins). Do not exceed quantity limits: 2 bottles (8 oz) for head lice or 4 bottles (16 oz) for scabies. Claims will be denied without proper prior authorization.
