About coding Paraphilia
The ICD-10-CM code for Paraphilia is F65.9 (Paraphilia, unspecified).
Within F65, choose F65.9 (Paraphilia, unspecified) only when documentation doesn't support a more specific option: fetishism (F65.0), Transvestic fetishism (F65.1), Exhibitionism (F65.2), Voyeurism (F65.3), Pedophilia (F65.4), Sadomasochism (F65.5) and other paraphilias (F65.8).
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.
