ICD-10-CM Code For Congenital Obstructive Defects Of Renal Pelvis And Congenital Malformations Of Ureter: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q62 includes congenital obstructive defects of the renal pelvis and congenital malformations of the ureter, covering anomalies such as pelviureteric junction obstruction and ureteral duplication or ectopic ureter. These ICD-10-CM diagnosis codes are used to document congenital urinary tract obstructions, anatomic abnormalities, and related complications such as hydronephrosis or impaired renal function. Accurate coding within the ICD-10-CM Q62 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM Q62: Congenital Obstructive Defects Of Renal Pelvis And Congenital Malformations Of Ureter Overview

This group includes congenital obstructive defects of the renal pelvis and congenital malformations of the ureter that affect urine flow and urinary tract anatomy. These conditions target the urinary system, specifically the kidney pelvis and ureteral structures. Accurate coding is important for clinical documentation and supports appropriate reimbursement by reflecting the complexity and severity of the congenital anomaly.

When to Use

Use a code from this group when documenting a congenital obstruction at the renal pelvis or a congenital ureteral malformation identified by imaging, clinical exam, or surgical findings. Select the most specific code to reflect the exact anatomic abnormality and any associated complications such as hydronephrosis or impaired renal function.

Typical Clinical Scenarios

A newborn with antenatal hydronephrosis detected on prenatal ultrasound is referred to pediatric urology after birth for postnatal renal and bladder ultrasound and a voiding cystourethrogram to evaluate urinary tract anatomy and obstruction. Imaging demonstrates unilateral dilation of the renal pelvis with narrowing at the ureteropelvic junction consistent with congenital obstruction of the renal pelvis; a congenital urinary tract malformation code from this group is assigned for the anatomic diagnosis and future follow-up. Typical codes: Q62.0, Q62.5
A school-age child presents with recurrent febrile urinary tract infections and intermittent flank pain; renal ultrasound and MAG3 renal scan reveal a duplicated collecting system with an obstructed upper pole moiety and associated ureterocele causing partial obstruction of the ipsilateral ureter. Because the obstructive anomaly of the ureter and renal pelvis explains the recurrent infections and impaired drainage, a congenital ureteral malformation code is used to document the structural abnormality driving management. Typical codes: Q62.31, Q62.32, Q62.39
An adult is incidentally found on CT abdomen performed for unrelated abdominal pain to have a previously undiagnosed congenital megaureter with significant dilation of the ureter and hydronephrosis; renal function testing shows reduced ipsilateral renal function and the patient is counseled about potential intervention. The congenital dilatation/obstructive malformation of the ureter or renal pelvis is coded to capture the chronic congenital abnormality contributing to the impaired renal drainage and function. Typical codes: Q62.60, Q62.61, Q62.69
