N31 — Neuromuscular dysfunction of bladder, not elsewhere classified
Is N31 billable?
No — N31 is a non-billable header code. N31 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 5 billable codes beneath N31.
