About coding appetite perversion
The ICD-10-CM code for appetite perversion is F50.89 (Other specified eating disorder). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F50.89.
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.
