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 Q63Overview

What is the ICD-10 code for other congenital malformations of kidney?

Q63 is the ICD-10-CM category for other congenital malformations of kidney, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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

No. This is a category header that groups the codes for other congenital malformations of kidney, and headers cannot be submitted on claims. Claims for other congenital malformations of kidney need a more specific code from this category, such as Q63.0, Q63.1, and Q63.2.

Can Q63 be reported with a code from N04?

Not as a rule. The Excludes1 note on Q63 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).
