N53.9Unspecified male sexual dysfunction

N53.9 is the ICD-10-CM diagnosis code for unspecified male sexual dysfunction. It belongs to category N53 (other male sexual dysfunction), block N40-N53 (diseases of male genital organs) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N53, choose N53.9 (Unspecified male sexual dysfunction) only when documentation doesn't support a more specific option: ejaculatory dysfunction (N53.1) and other male sexual dysfunction (N53.8).

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 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544) and DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), in MDC 12 (Diseases and Disorders of the Male Reproductive System), 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 on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

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 608.89 (other specified disorders of male genital organs).
