N31.0Uninhibited neuropathic bladder, not elsewhere classified

N31.0 is the ICD-10-CM diagnosis code for Uninhibited neuropathic bladder, not elsewhere classified. It belongs to category N31 (neuromuscular dysfunction of bladder, not elsewhere classified), 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 N31 (neuromuscular dysfunction of bladder, not elsewhere classified), N31.0 is specifically for Uninhibited neuropathic bladder, not elsewhere classified. Related codes cover reflex neuropathic bladder, not elsewhere classified (N31.1), flaccid neuropathic bladder, not elsewhere classified (N31.2), other neuromuscular dysfunction of bladder (N31.8) and neuromuscular dysfunction of bladder, unspecified (N31.9).

Use an additional code to identify any associated urinary incontinence (N39.3-N39.4-).

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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), 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 596.54 (neurogenic bladder NOS).
