About coding psychogenic aphagia
The ICD-10-CM code for psychogenic aphagia is F50.9 (Eating disorder, unspecified).
Within F50, choose F50.9 (Eating disorder, unspecified) only when documentation doesn't support a more specific option: Anorexia nervosa (F50.0), Bulimia nervosa (F50.2) and other eating disorders (F50.8).
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.
