About coding Overflow incontinence
The ICD-10-CM code for Overflow incontinence is N39.490 (Overflow incontinence).
Within N39.49 (other specified urinary incontinence), N39.490 is specifically for Overflow incontinence. Related codes cover Coital incontinence (N39.491), postural (urinary) incontinence (N39.492) 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.
