About coding bladder sphincter diverticulum
The ICD-10-CM code for bladder sphincter diverticulum is N32.3 (Diverticulum of bladder). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N32.3.
Within N32 (other disorders of bladder), N32.3 is specifically for diverticulum of bladder. Related codes cover Bladder-neck obstruction (N32.0), Vesicointestinal fistula (N32.1), Vesical fistula, not elsewhere classified (N32.2), other specified disorders of bladder (N32.8) and bladder disorder, unspecified (N32.9).
Don't report N32.3 together with the conditions in its Excludes1 note: congenital diverticulum of bladder (Q64.6) and diverticulitis of bladder (N30.8-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
