About N39.492

N39.492 is the ICD-10-CM diagnosis code for postural (urinary) incontinence. It belongs to category N39 (other disorders of urinary system), block N30-N39 (other diseases of the urinary system) 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 N39.49 (other specified urinary incontinence), N39.492 is specifically for postural (urinary) incontinence. Related codes cover Overflow incontinence (N39.490), Coital incontinence (N39.491) and other specified urinary incontinence (N39.498).

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 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 was added in FY2017, effective October 1, 2016.

Before ICD-10, this condition was coded in ICD-9-CM as 788.39 (other urinary incontinence).
