NUEDEXTA® (dextromethorphan HBr and quinidine sulfate) HCP Treatment

Prior authorization

Some insurance providers and Medicare Part D plans may require prior authorization (PA) for the patients or residents for whom you prescribe NUEDEXTA. Each health plan will determine the PA criteria for its formulary. There are 4 common pieces of documentation generally requested by plans as part of their PA process to ensure that NUEDEXTA is being used safely and appropriately.

These are:

  • Documentation of primary diagnosis
  • Documentation of underlying conditions
  • Documentation that NUEDEXTA is not contraindicated for the patient (please refer to the Prescribing Information)
  • Documentation of medical or clinical history
  • For reauthorization: Usually at the start of the year, documentation of symptom improvement and/or improvement to the CNS-LS scores may be required

CNS-LS=Center for Neurologic Study-Lability Scale; ICD-10-CM=International Classification of Diseases, Tenth Revision, Clinical Modification; PBA=pseudobulbar affect.


NUEDEXTA Connect partners with CoverMyMeds® to streamline prior authorizations for providers and pharmacists, and works to provide many other patient support services that remove access barriers to therapy.
