Q62.2Congenital megaureter

Q62.2 is the ICD-10-CM diagnosis code for congenital megaureter. It belongs to category Q62 (congenital obstructive defects of renal pelvis and congenital malformations of ureter), 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 Q62 (congenital obstructive defects of renal pelvis and congenital malformations of ureter), Q62.2 is specifically for congenital megaureter. Related codes cover congenital hydronephrosis (Q62.0), congenital occlusion of ureter (Q62.1), other obstructive defects of renal pelvis and ureter (Q62.3), agenesis of ureter (Q62.4), duplication of ureter (Q62.5), malposition of ureter (Q62.6), congenital vesico-uretero-renal reflux (Q62.7) and other congenital malformations of ureter (Q62.8).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 753.22 (congenital obstruction of ureterovesical junction).
