About coding Marion's disease
The ICD-10-CM code for Marion's disease is N32.0 (Bladder-neck obstruction).
Within N32 (other disorders of bladder), N32.0 is specifically for Bladder-neck obstruction. Related codes cover Vesicointestinal fistula (N32.1), Vesical fistula, not elsewhere classified (N32.2), diverticulum of bladder (N32.3), other specified disorders of bladder (N32.8) and bladder disorder, unspecified (N32.9).
Don't report N32.0 together with the conditions in its Excludes1 note: congenital bladder-neck obstruction (Q64.3-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

- congenital bladder-neck obstruction (Q64.3-)
