About coding bladder neurogenic
The ICD-10-CM code for bladder neurogenic is N31.9 (Neuromuscular dysfunction of bladder, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N31.9.
Within N31, choose N31.9 (Neuromuscular dysfunction of bladder, unspecified) only when documentation doesn't support a more specific option: Uninhibited neuropathic bladder, not elsewhere classified (N31.0), reflex neuropathic bladder, not elsewhere classified (N31.1), flaccid neuropathic bladder, not elsewhere classified (N31.2) and other neuromuscular dysfunction of bladder (N31.8).
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.
