CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

Q64.19 is a billable ICD-10-CM diagnosis code for other exstrophy of urinary bladder. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 698 through 700. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 7 closely related codes. The code is exempt from POA reporting. Coders also document this condition as covered exstrophy of bladder. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Genitourinary congenital anomalies.
