Postprocedural hepatorenal syndrome

This code describes the development of hepatorenal syndrome (HRS) as a direct consequence of a medical or surgical procedure. HRS is a severe and potentially life-threatening complication characterized by acute kidney injury in patients with advanced liver disease, typically cirrhosis, without intrinsic renal pathology. The postprocedural context implies that the intervention itself triggered or exacerbated the underlying liver dysfunction leading to renal failure.

Use this code when documentation clearly links the onset of hepatorenal syndrome to a recent medical or surgical procedure. This includes scenarios where procedures like paracentesis, transjugular intrahepatic portosystemic shunt (TIPS) placement, or other interventions in patients with pre-existing liver disease precipitate renal failure. Documentation should specify both the procedure performed and the subsequent development of HRS.

• Ensure documentation explicitly states the causal link between the procedure and the development of hepatorenal syndrome.
• Do not use this code for HRS unrelated to a procedure; instead, use K76.7 (Hepatorenal syndrome, not elsewhere classified).
• Code the underlying liver disease (e.g., cirrhosis) and the specific procedure performed as additional diagnoses.
