Changes to ICD-10-CM Codes for DSM-5 Diagnoses

Revised ICD-10-CM codes for 2018, released by the National Center for Health Statistics (NCHS), took effect on October 1. The list included new, updated, or deleted codes for diagnoses in ICD-10-CM, including some 65 codes related to mental health conditions in DSM-5. All practitioners and payers must use the codes.

Coding updates are typically made to provide greater diagnostic specificity, which in turn impacts reimbursement levels.

NCHS is a federal agency within the Centers for Disease Control and Prevention, which oversees the ICD-10-CM. The ICD-10 Coordination and Maintenance Committee, a federal committee co-chaired by a representative from NCHS and from the Centers for Medicare and Medicaid Services, approves proposed changes to ICD on a yearly basis.

The coding changes that impact DSM-5 are posted on the APA website. The diagnoses are listed alongside two columns—one column lists the codes that were used through September 30, and the other column lists the new codes that became effective October 1. Two versions of the table are provided—one listing the codes in numerical order and the other listing them in the order in which they appear in DSM-5. ■
