Cystic kidney disease, unspecified

This code signifies a diagnosis of cystic kidney disease when the specific type of cystic kidney disease is not documented or cannot be determined. It indicates the presence of fluid-filled sacs within the kidney tissue without further specification of etiology or morphology.

Use this code when the medical record clearly states "cystic kidney disease" but lacks details to classify it further (e.g., polycystic, medullary, simple). This code is appropriate when the provider has not specified the type of cyst or when diagnostic workup is incomplete or inconclusive regarding the specific type of cystic kidney disease.

• Avoid using this code if documentation specifies a particular type of cystic kidney disease (e.g., autosomal dominant polycystic kidney disease).
• Query the provider for more specific documentation if possible to allow for a more precise code assignment.
• This code should be sequenced as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
