N32.0Bladder-neck obstruction

N32.0 is the ICD-10-CM diagnosis code for Bladder-neck obstruction. It belongs to category N32 (other disorders of bladder), block N30-N39 (other diseases of the urinary system) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003), DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 596.0 (bladder neck obstruction).
