2025 ICD-10-CM code Q61.9
Cystic kidney disease, unspecified.
Medical necessity is established by the presence of cystic kidney disease documented through appropriate diagnostic testing. Further investigation and specific treatment will depend on the type and severity of the condition.
- Congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- Q61-Q64 Congenital malformations of the urinary system
In simple words: This code represents a congenital condition characterized by cysts in the kidneys where the specific type is not known.
Cystic kidney disease, unspecified. Meckel-Gruber syndrome
Example 1: A newborn is diagnosed with multiple cysts in both kidneys, but the underlying cause and specific type of cystic kidney disease are not yet determined. The diagnosis is coded as Q61.9., A fetus is found to have cystic kidneys on ultrasound during prenatal screening. Further testing is planned after birth to determine the exact nature of the cystic disease. Initially, Q61.9 is used., An infant presents with enlarged kidneys and other abnormalities suggestive of Meckel-Gruber syndrome, which can include cystic kidneys. Until a definitive diagnosis is confirmed, Q61.9 may be used to document the kidney findings.
Documentation should include imaging studies (such as ultrasound or CT scan) demonstrating the presence of kidney cysts. Any additional clinical findings or genetic testing results relevant to the diagnosis should also be noted.
** Excludes1: acquired cyst of kidney (N28.1) Potter's syndrome (Q60.6) Excludes2: inborn errors of metabolism (E70-E88)
