The ICD-10-CM code for Schizophreniform psychosis is F20.81 (Schizophreniform disorder). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F20.81.
Within F20.8 (other schizophrenia), F20.81 is specifically for Schizophreniform disorder. Related codes cover other schizophrenia (F20.89).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
