Patient EducationClinical

Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters.

Questions About Q63.2Overview

What is the ICD-10 code for ectopic kidney?

The ICD-10-CM code for ectopic kidney is Q63.2 (sometimes written as Q632). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q63.2 (Other congenital malformations of kidney) a billable code?

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

What MS-DRG does Q63.2 group to?

When ectopic kidney 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 Q63.2 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 ectopic kidney on inpatient claims. The code appears in the Congenital malformations of the urinary system (Q60-Q64) range of the CMS exempt list.

Can Q63.2 be reported with a code from N04?

Not as a rule. The Excludes1 note at Q63, which applies to Q63.2, lists "congenital nephrotic syndrome (N04.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
