Changes to ICD-10-CM Codes for DSM-5 Diagnoses Effective October 1

Revised 2018 ICD-10-CM codes, released by the National Center for Health Statistics (NCHS), are scheduled to take effect on October 1, 2017. The codes include new, updated, or deleted codes for diagnoses listed in ICD-10-CM, including some 65 codes related to mental health conditions listed 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 listing the codes that were used through September 30, 2017, and the other column listing the new codes that will become 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 that they appear in DSM-5.
