Substance Use Disorder Secondary to PTSD
38 CFR § 4.130 (general formula); compensable when secondary to a service-connected mental disorder
Overview
Under Allen v. Principi (2001), substance use disorder is compensable when caused or aggravated by a service-connected mental health condition.
VA does not assign a separate rating — symptoms are typically evaluated together with the underlying PTSD/depression under the General Mental Health Formula.
Self-medication patterns, ER visits, and treatment program records are critical evidence.
