Multiple categories may be assigned as necessary to describe the clinical presentation. Mental disorder affecting disorders and diseases classified elsewhere • The presence of a mental, behavioural or neurodevelopmental disorder that adversely affects the manifestation, treatment or course of a disorder or disease classified in another chapter is required for diagnosis (e.g. a woman with bulimia nervosa and type 1 diabetes mellitus who skips insulin doses as a way to avoid weight gain that would otherwise be caused by her binge eating). Psychological symptoms affecting disorders and diseases classified elsewhere • The presence of psychological symptoms that do not meet the diagnostic requirements for a mental, behavioural or neurodevelopmental disorder that adversely affect the manifestation, treatment or course of a disorder or disease classified in another chapter is required for diagnosis (e.g. depressive symptoms interfering with rehabilitation following surgery). Personality traits or coping style affecting disorders and diseases classified elsewhere • The presence of personality traits or coping styles that do not meet the diagnostic requirements for a mental, behavioural or neurodevelopmental disorder that adversely affect the manifestation, treatment or course of a disorder or disease classified in another chapter is required for diagnosis (e.g. pathological denial of the need for surgery in a patient with cancer; hostile, pressured behaviour contributing to heart disease). Maladaptive health behaviours affecting disorders and diseases classified elsewhere • The presence of maladaptive health behaviours that adversely affect the manifestation, treatment or course of a disorder or disease classified in another chapter is required for diagnosis (e.g. overeating, lack of exercise). 6E40.0 6E40.1 6E40.2 6E40.3 Psychological or behavioural factors affecting disorders and diseases classified elsewhere
