New codes were created to uniquely identify types of urinary incontinence that are not currently classified in ICD-10-CM. Two new codes were added within subcategory N39.49, Other specified urinary incontinence, to capture coital incontinence (N39.491) and postural (urinary) incontinence (N39.492).
Urinary incontinence is the involuntary loss of urine and is a common problem for men and women over age 65, but does occur in younger patients as well. Multiple pregnancies, being overweight, and genetic weaknesses can increase the risk.
Code N39.491, Coital incontinence, was added to capture the involuntary loss of urine (incontinence) that occurs in women during intercourse. Coital incontinence is due to underlying pelvic floor dysfunction and the causes may be due to several factors.
Code N39.492, Postural (urinary) incontinence, was created to capture the involuntary loss of urine associated with change of body position, for example, rising from a seated or lying position.
An inclusion term was added under code N39.42, Incontinence without sensory awareness, to indicate that insensible (urinary) incontinence is appropriately captured with this code. Insensible incontinence results from stress leakage of small amounts of urine and is a very common type of urinary incontinence.
