About the F45 Code Range
Somatoform disorders involve physical symptoms that suggest a medical condition but are not fully explained by one, a substance, or another mental disorder. The symptoms cause significant distress or interfere with daily functioning, and they are not under voluntary control.
F45 separates somatization disorder, undifferentiated somatoform disorder, hypochondriacal disorders, and pain disorders related to psychological factors. It also has categories for other and unspecified somatoform disorders.
Hypochondriacal disorders split into unspecified hypochondriacal disorder, hypochondriasis, body dysmorphic disorder, and other hypochondriacal disorders. Pain disorders split between pain exclusively related to psychological factors and pain with related psychological factors.
