Neuromuscular dysfunction of bladder, not elsewhere classified (N31) ICD-10-CM
The N31 code range covers neuromuscular dysfunction of bladder, not elsewhere classified with 6 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the N31 Code Range
Neuromuscular bladder dysfunction involves problems with the bladder’s nerve or muscle function. N31 groups these conditions when they are not classified elsewhere.
The subdivisions distinguish uninhibited N31.0, reflex N31.1, and flaccid N31.2 neuropathic bladder. N31.8 identifies other neuromuscular bladder dysfunction, while N31.9 identifies unspecified neuromuscular bladder dysfunction.
