About F65.9

F65.9 is the ICD-10-CM diagnosis code for Paraphilia, unspecified. It belongs to category F65 (paraphilias), block F60-F69 (disorders of adult personality and behavior) 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 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 302.9 (unspecified psychosexual disorder).
