Beginning October 1, 2015, providers will be required to use ICD-10 codes for services provided on or after October 1, 2015. For services provided through September 30, 2015, ICD-9 codes must be used.

Claims containing ICD-9 codes for dates of services on or after October 1, 2015, may be returned as unprocessable. Remember that ICD-10 codes must only be used for services provided on or after October 1, 2015.

Claims should not contain both ICD-9 codes and ICD-10 codes. Claims that are billed with both ICD-9 and ICD-10 diagnosis codes on the same claim may also be considered unprocessable. Therefore, services rendered prior to October 1, 2015 should be billed separately than services rendered from October 1, 2015 forward.

IMPORTANT REMINDER: Providers who bill electronically should contact their software vendors, if they have not done so already, to insure that they will be ready to submit claims with ICD-10 codes by October 1, 2015.

To assist members with the transition to ICD-10, the APA has developed a question and answer guide on how to use the DSM-5 when transitioning to ICD-10, as well as a 5-minute video that clarifies how the ICD-10 codes are included in the DSM-5.  The guide and video can be found here.
