Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
Assign Q00-QA1 codes for documented congenital anomalies or genetic disorders at any age, coding non-inherent manifestations separately and sequencing Z38 first on the birth admission.

Q64 MS-DRGs
As the principal diagnosis, the billable codes under Q64 group to MS-DRG 698, 699, 700, 729, or 730 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
- DRG 698 Other Kidney and Urinary Tract Diagnoses with MCC (21 of 22 codes)
- DRG 699 Other Kidney and Urinary Tract Diagnoses with CC (21 of 22 codes)
- DRG 700 Other Kidney and Urinary Tract Diagnoses without CC/MCC (21 of 22 codes)
- DRG 729 Other Male Reproductive System Diagnoses with CC/MCC (1 of 22 codes)
- DRG 730 Other Male Reproductive System Diagnoses without CC/MCC (1 of 22 codes)
About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
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. It goes to your bladder, which stores the urine until you go to the bathroom.
