ICD-10 Code F19.19 – Other psychoactive substance abuse with unspecified psychoactive substance-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.19 – Other psychoactive substance abuse with unspecified psychoactive substance-induced disorder
What it is
This code identifies abuse of other psychoactive substances when the record also documents an unspecified substance-induced disorder. It applies when the substance involved is not better classified elsewhere and the induced disorder is not further specified.
Clinical signs
Clinical features vary; refer to documentation. Records may note problematic use plus mental or behavioral changes linked to a psychoactive substance, but the induced disorder is not named or detailed.
When to use this code
Use this code when the provider documents substance abuse and an unspecified substance-induced disorder, and no more specific code is available. It may fit encounters where the substance is described as “other” or the exact agent is not identified. Check documentation for the relationship between use and the induced disorder.
Do not use for
Do not use this code if the substance is known and has a more specific ICD-10 option. Do not use it when the record does not support abuse or does not link the disorder to substance use.
Coding tip
Confirm both the abuse and the substance-induced disorder in the provider’s note before assigning F19.19.
