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.

When congenital malformation of kidney, unspecified 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 Q63.9 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 malformation of kidney, unspecified on inpatient claims. The code appears in the Congenital malformations of the urinary system (Q60-Q64) range of the CMS exempt list.
Can Q63.9 be reported with a code from N04?
Not as a rule. The Excludes1 note at Q63, which applies to Q63.9, 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).
