About N39.44
N39.44 is the ICD-10-CM diagnosis code for nocturnal enuresis. 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 N39.4 (other specified urinary incontinence), N39.44 is specifically for nocturnal enuresis. Related codes cover Urge incontinence (N39.41), incontinence without sensory awareness (N39.42), Post-void dribbling (N39.43), continuous leakage (N39.45), mixed incontinence (N39.46) and other specified urinary incontinence (N39.49).
The conditions in its Excludes2 note aren't part of N39.44, but may be coded alongside it if the patient has both: nocturnal polyuria (R35.81).
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 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 788.36 (nocturnal enuresis).
