About coding psychosexual disorder
The ICD-10-CM code for psychosexual disorder is F65.9 (Paraphilia, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F65.9.
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.
