F52.9Unspecified sexual dysfunction not due to a substance or known physiological condition

F52.9 is the ICD-10-CM diagnosis code for unspecified sexual dysfunction not due to a substance or known physiological condition. It belongs to category F52 (sexual dysfunction not due to a substance or known physiological condition), block F50-F59 (behavioral syndromes associated with physiological disturbances and physical factors) 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 F52, choose F52.9 (Unspecified sexual dysfunction not due to a substance or known physiological condition) only when documentation doesn't support a more specific option: Hypoactive sexual desire disorder (F52.0), sexual aversion disorder (F52.1), sexual arousal disorders (F52.2), orgasmic disorder (F52.3), premature ejaculation (F52.4), vaginismus not due to a substance or known physiological condition (F52.5), dyspareunia not due to a substance or known physiological condition (F52.6) and other sexual dysfunction not due to a substance or known physiological condition (F52.8).

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 is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

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 302.70 (psychosexual dysfunction, unspecified) and V41.7 (problems with sexual function).
