Chronic kidney disease, unspecified

This code signifies the presence of long-standing kidney dysfunction without further specification of its stage or underlying cause. It indicates a persistent, often progressive, impairment of renal function that has not been precisely characterized by the provider.

Use this code when documentation confirms chronic kidney disease but lacks details regarding the specific stage (e.g., stage 1-5) or the etiology (e.g., diabetic nephropathy, hypertensive nephropathy). This is typically an interim or less specific diagnosis when more detailed information is unavailable or not yet determined.

• Avoid using this code if a more specific stage of chronic kidney disease (e.g., 585.1-585.6) is documented.
• Always query the provider for clarification on the stage and etiology of CKD if possible, to allow for more specific coding.
• This code should not be used for acute kidney injury (e.g., 584.x) or end-stage renal disease (585.6) when those specific conditions are documented.
