In the August 7th Communication Alert regarding the conversion from DSM IV to DSM 5, we stated that all claims submitted to HFS after October 1st should use ICD 10 codes, regardless of the date of service. This was a mistake.
Only claims for dates of service on or after October 1st should use ICD 10 codes. Claims for dates of service prior to October 1st must use ICD 9 codes.
We are sorry for any and all confusion caused by this misstatement.
Also, as a reminder, and as stated in the DMH July 22nd Communication Alert referencing the Batch Registration Guide Layout effective October 1st, 2015, registrations using the batch registration process or registrations submitted via ProviderConnect with registration dates prior to October 1, 2015 will need to continue to have diagnoses based on the ICD-9 or DSM-IV-TR diagnostic taxonomies. This is consistent with CMMS and HFS rules for claims submission. DSM-5/ICD-10 codes should only be submitted for registrations with registration dates on or after October 1, 2015. This rule pertains to authorization requests as well.
