About F50

F50 is the ICD-10-CM diagnosis code for eating disorders. It belongs to 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 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: F50.0 (nervosa), F50.2 (nervosa), F50.8 (disorders) and F50.9 (unspecified).

Don't report F50 together with the conditions in its Excludes1 note: anorexia NOS (R63.0), feeding problems of newborn (P92.-) and polyphagia (R63.2).

The conditions in its Excludes2 note aren't part of F50, but may be coded alongside it if the patient has both: feeding difficulties (R63.3-) and feeding disorder in infancy or childhood (F98.2-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
