Both DSM-5 and ICD-9 codes are used for diagnosis and are exactly the same codes. For reporting purposes it is required to report ICD-9 codes to insurance payers. Most payers require ICD-9 codes to be billed on electronic or paper claims. Therefore, the codes are the same in DSM as in ICD-9, however keep in mind the descriptions may be different.

DSM uses a different pathway directing them to the code used for billing. DSM endorses most Behavioral health ICD-9 codes, however some ICD-9 codes are excluded in DSM-5.

The most important aspect of using DSM and ICD-9 is that the diagnosis supports the treatment and is medically necessary.

Everyone will be required to report diagnosis codes using ICD-10 starting October 2015.
