About the F50–F59 Code Range
ICD-10 codes F50-F59 categorize behavioral syndromes linked to physiological disturbances and physical factors, mainly focusing on eating disorders, sleep disorders, sexual dysfunctions, postpartum mental disorders, and substance abuse not involving psychoactive drugs.
This range includes detailed classifications of eating disorders such as anorexia nervosa (including restricting and binge-eating/purging types), bulimia nervosa, binge eating disorder, and less common conditions like pica and rumination disorder. Terms like "Prepubertal anorexia nervosa" or "Binge eating behavior" help clarify specific diagnoses under codes like F50.0 and F50.81. The sleep disorders section (F51) covers non-substance-related issues like insomnia, sleepwalking, and nightmare disorder, with terms such as "Primary insomnia" and "Sleepwalking [somnambulism]" aiding clinical coding precision. Sexual dysfunction codes (F52) address problems like hypoactive sexual desire disorder and male or female orgasmic disorder, identified by synonyms including "Lack or loss of sexual desire" and "Failure of orgasm." Postpartum mood and psychotic disorders (F53) describe postpartum depression and puerperal psychosis. Furthermore, F54 highlights psychological factors affecting other medical conditions, whereas F55 involves abuse of non-psychoactive substances like laxatives and vitamins. Finally, F59 covers unspecified behavioral syndromes associated with physiological disturbances.
