About ICD-9-CM 294.8
294.8 is an ICD-9-CM diagnosis code for other persistent mental disorders due to conditions classified elsewhere. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as F06.0 (Psychotic disorder with hallucinations due to known physiological condition) and F06.8 (Other specified mental disorders due to known physiological condition). All of these are approximate matches, so review the record to pick the right one.
