Q64.0Epispadias

Q64.0 is the ICD-10-CM diagnosis code for epispadias. It belongs to category Q64 (other congenital malformations of urinary system), block Q60-Q64 (congenital malformations of the urinary system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q64 (other congenital malformations of urinary system), Q64.0 is specifically for epispadias. Related codes cover exstrophy of urinary bladder (Q64.1), congenital posterior urethral valves (Q64.2), other atresia and stenosis of urethra and bladder neck (Q64.3), malformation of urachus (Q64.4), congenital absence of bladder and urethra (Q64.5), congenital diverticulum of bladder (Q64.6), other and unspecified congenital malformations of bladder and urethra (Q64.7), other specified congenital malformations of urinary system (Q64.8) and 1 more.

Don't report Q64.0 together with the conditions in its Excludes1 note: hypospadias (Q54.-).

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 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544) and DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), in MDC 12 (Diseases and Disorders of the Male Reproductive System), 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 is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

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 752.62 (epispadias).
