ICD-10-CM Q62.2
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

Q62.2 is a billable ICD-10-CM diagnosis code for congenital megaureter. 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 congenital dilatation of ureter. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Genitourinary congenital anomalies.

Questions About Q62.2Overview

What is the ICD-10 code for congenital megaureter?

The ICD-10-CM code for congenital megaureter is Q62.2 (sometimes written as Q622). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q62.2 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report congenital megaureter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Q62.2 group to?

When congenital megaureter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 699, 698, 700, with relative weights from 0.6740 to 1.6400 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q62.2 a CC or MCC?

CMS lists Q62.2 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 7 closely related codes in its exclusion list.

Is Q62.2 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for congenital megaureter on inpatient claims. The code appears in the Congenital malformations of the urinary system (Q60-Q64) range of the CMS exempt list.
