About F50.89

F50.89 is the ICD-10-CM diagnosis code for other specified eating disorder. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F50.8, choose F50.89 (Other specified eating disorder) only when documentation doesn't support a more specific option: binge eating disorder (F50.81), Avoidant/restrictive food intake disorder (F50.82), Pica in adults (F50.83) and rumination disorder in adults (F50.84).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 887 (Other Mental Disorder Diagnoses, relative weight 1.1139), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 307.54 (psychogenic vomiting) and 307.59 (other disorders of eating).
