About F50.02

F50.02 is the ICD-10-CM diagnosis code for Anorexia nervosa, binge eating/purging type. It belongs to category F50 (eating disorders), block F50-F59 (behavioral syndromes associated with physiological disturbances and physical factors) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within F50.0 (Anorexia nervosa), F50.02 is specifically for Anorexia nervosa, binge eating/purging type. Related codes cover unspecified (F50.00) and restricting type (F50.01).

To report this condition, pick the subcode that matches the documentation: F50.020 (mild), F50.021 (moderate), F50.022 (severe), F50.023 (extreme), F50.024 (in remission) and F50.029 (unspecified).

Don't report F50.02 together with the conditions in its Excludes1 note: bulimia nervosa (F50.2-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2025 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 307.1 (Anorexia nervosa).
