Acute On Chronic Renal Disease

Usage Guidelines & Examples

• Use this diagnosis code when a patient with known chronic renal disease presents with acute worsening of renal function.
• Do not use this code if the patient has only acute renal failure without a history of chronic disease.
• Similar codes include N17 for acute kidney failure and N18 for chronic kidney disease, but they do not specify the acute on chronic aspect.
• Common errors include failing to document the chronic aspect or misclassifying acute renal failure as primary.
• In complex cases, ensure to differentiate between acute exacerbation and new onset of renal failure.
