Acute hepatitis C with hepatic coma

This code signifies an acute infection with the hepatitis C virus that has progressed to cause hepatic encephalopathy, a severe neurological complication due to liver failure. The liver's inability to detoxify the blood leads to the accumulation of toxins, affecting brain function and resulting in a coma.

Apply this code when documentation explicitly states acute hepatitis C with evidence of hepatic coma. This typically occurs in patients presenting with new-onset hepatitis C infection and altered mental status, confusion, or unresponsiveness directly attributed to liver dysfunction.

• Ensure documentation clearly specifies "acute" hepatitis C and "hepatic coma," not just general liver failure or encephalopathy.
• Do not confuse with chronic hepatitis C or acute hepatitis C without coma; separate codes exist for those conditions.
• Sequence this code as the principal diagnosis when it is the primary reason for the encounter, followed by any associated manifestations or complications.
