2025 ICD-10-CM code Q63.8
(Active) Effective Date: N/A Congenital malformations of the urinary system - Other congenital malformations of kidney 18 Feed
Other specified congenital malformations of kidney. Congenital renal calculi.
Medical necessity for interventions related to congenital kidney malformations must be documented.This includes the severity of the condition, the potential risks and benefits of treatment options, and the expected impact on the patient's health and quality of life. For instance, if a congenital malformation causes recurrent infections or impaired renal function, the medical necessity of surgical correction or other interventions is established.
Diagnosis and management of congenital kidney malformations fall under the purview of pediatric nephrologists, urologists, and/or geneticists, depending on the specific condition.They are responsible for confirming the diagnosis, outlining a treatment plan, and providing ongoing care.
In simple words: This code indicates a birth defect affecting the kidneys, specifically those not covered by other, more specific codes.An example of this is being born with kidney stones.
This code encompasses congenital malformations of the kidney that are not classified under other specific Q63 codes, such as accessory kidney (Q63.0), lobulated kidney (Q63.1), ectopic kidney (Q63.2), or hyperplastic kidney (Q63.3). One example included under this code is congenital renal calculi (kidney stones present at birth).
Example 1: A newborn infant undergoes renal ultrasound which reveals the presence of kidney stones. The infant is diagnosed with congenital renal calculi, and Q63.8 is assigned., A fetus is diagnosed prenatally with oligohydramnios and small kidneys with poorly developed tubules on ultrasound. Further investigation reveals Renal tubular dysgenesis. After birth, the infant's condition is coded as Q63.8., A child presents with recurrent urinary tract infections. Imaging studies reveal an unusual kidney shape that is not consistent with horseshoe kidney or other defined malformations. The physician diagnoses the child with an unspecified congenital kidney malformation, coded as Q63.8.
Thorough clinical documentation should support the use of Q63.8, including imaging reports (ultrasound, CT, MRI), laboratory findings, and operative reports if surgery is performed.Any specific diagnostic findings should be clearly described, such as the size and location of calculi or the specific nature of the malformation. Supporting documentation should also describe the impact of the malformation on kidney function.
