New Diagnostic Codes for Substance Use Disorders and ARFID in 2018

January 2018 ~

The federal agency responsible for the use of the ICD-10 in the United States, the National Center for Health Statistics (NCHS), has released an updated version of the ICD-10-CM for 2018.

This year, there are several important updates involving diagnostic codes within the Mental, Behavioral, and Neurodevelopmental chapter (F00-F99), most of which relate to new specifiers, which occur after the decimal point of the parent code, for substance abuse disorders. Additionally, the code for avoidant/restrictive food intake disorder (ARFID) has been moved from “Other specified eating disorder” to “Other eating disorder.”

The following updates are intended to improve the coding specificity of the diagnoses for more accurate diagnostic recording and reimbursement:
