LOADING
Substance Use (Secondary Symptom) VA Disability Rating is rated by the U.S. Department of Veterans Affairs under DC 9411 of 38 C.F.R. § 4.130 across 5 severity tiers (100% -- Total occupational and social impairment / 70% -- Deficiencies in most areas / 50% -- Reduced reliability and productivity / 30% -- Occasional decrease in work efficiency / 10% -- Mild or transient symptoms). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Substance use as a secondary symptom of PTSD or other mental health conditions is ratable under Allen v. Principi (2001). The VA cannot deny service connection for substance use disorder when it results from a service-connected mental health condition.
Substance Use (Secondary Symptom) (DC 9411) is evaluated under 38 C.F.R. § 4.130 using the mental health rating framework. Because it is rated by analogy to the general schedule, the 5 levels below describe the body-system criteria the VA applies — the percentage assigned to Substance Use (Secondary Symptom) depends on the specific findings (range of motion, frequency, severity, or functional loss) documented at the C&P exam and in the medical record.
Rating criteria reference 38 C.F.R. Part 4 (Schedule for Rating Disabilities). This entry has not yet undergone editorial review against the live regulation text — consult the authoritative source directly before relying on the criteria shown.
