About the F50–F59 Code Range

These conditions connect behavior with eating, sleep, sexual function, childbirth, physical illness, or abuse of non-psychoactive substances.

F50 separates eating disorders into anorexia nervosa, bulimia nervosa, other disorders, and an unspecified disorder. F51 separates sleep disorders by type, including insomnia, sleepwalking, sleep terrors, and nightmares. F52 separates sexual dysfunction by type, including disorders of desire, arousal, and orgasm. The F51 and F52 titles specify that these disorders are not due to a substance or known physiological condition.

F53 distinguishes depression from psychosis associated with the period after childbirth. F54 identifies psychological and behavioral factors associated with diseases classified elsewhere. F55 separates abuse of non-psychoactive substances by substance, such as antacids, laxatives, and vitamins. F59 is the unspecified behavioral syndrome category in this group.
