Official Coding Guidelines

Medical conditions due to psychoactive substance use/abuse/dependence

4) Medical Conditions Due to Psychoactive Substance Use, Abuse and Dependence Medical conditions due to substance use, abuse, and dependence are not classified as substance-induced disorders. Assign the diagnosis code for the medical condition as directed by the Alphabetical Index along with the appropriate psychoactive substance use, abuse or dependence code. For example, for alcoholic pancreatitis due to alcohol dependence, assign the appropriate code from subcategory K85.2, Alcohol induced acute pancreatitis, and the appropriate code from subcategory F10.2, such as code F10.20, Alcohol dependence, uncomplicated. It would not be appropriate to assign code F10.288, Alcohol dependence with other alcohol-induced disorder.

Criteria for assigning “in remission” codes (F10-F19)

1) In Remission Selection of codes describing “in remission” for categories F10-F19, Mental and behavioral disorders due to psychoactive substance use (categories F10-F19 with -.11, -.21, -.91) requires the provider’s clinical judgment and are assigned only on the basis of provider documentation (as defined in the Official Guidelines for Coding and Reporting), unless otherwise instructed by the classification.
