About coding bladder paralysis
The ICD-10-CM code for bladder paralysis is N31.2 (Flaccid neuropathic bladder, not elsewhere classified).
Within N31 (neuromuscular dysfunction of bladder, not elsewhere classified), N31.2 is specifically for flaccid neuropathic bladder, not elsewhere classified. Related codes cover Uninhibited neuropathic bladder, not elsewhere classified (N31.0), reflex neuropathic bladder, not elsewhere classified (N31.1), 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.
