Coverage Decisions for Drugs

Drug therapy for neuropathic pain - effective January 1, 2019


Coverage decision

Tricyclic antidepressants, duloxetine, and gabapentin are covered for neuropathic pain (see definition below) when associated with a work-related condition or occupational disease. Pregabalin requires prior authorization.

Certain formulations of capsaicin, menthol, and lidocaine are covered for localized neuropathic pain or when used as adjunctive therapy.  Use our drug lookup tool to check coverage status of specific products.

Opioids do not have good quality evidence to support their use in the treatment of neuropathic pain. Coverage of opioids is subject to department guidelines and rules.

The treatment of trigeminal neuralgia is considered separately, as evidence supports use of carbamazepine and oxcarbazepine for this specific indication.

Prescribing of drug therapy to treat neuropathic pain should be consistent with FDA-recommended dosing guidelines and contraindications to use and should account for other patient-specific factors.

This coverage decision is based on a review of literature and evidence-based guidelines developed by: the International Association for the Study of Pain (IASP), Neuropathic Pain Special Interest Group, European Federation of Neurological Societies, Canadian Pain Society, and a collaboration between the American Academy of Neurology, the American Association of Neuromuscular and Electrodiagnostic Medicine, and the American Academy of Physical Medicine and Rehabilitation.
