What CMS assigns to F02

None of the 24 codes is assigned a clinical group. All 24 count toward the Psychotic, major depressive, and dissociative disorders, includes unspecified dementia, eating disorder and intellectual disabilities comorbidity subgroup. None can lead a claim. CMS attaches a code-first note to all 24.

  • Psychotic, major depressive, and dissociative disorders, includes unspecified dementia, eating disorder and intellectual disabilities: counts toward the high comorbidity tier only in an interaction pair.
