Diaphragmatic hernia with gangrene

This code signifies a diaphragmatic hernia that has progressed to tissue necrosis due to compromised blood supply. This is a severe complication where a portion of an organ, typically intestine, has herniated through the diaphragm and become gangrenous.

Apply this code when documentation explicitly states a diaphragmatic hernia with associated gangrene. This typically occurs in incarcerated or strangulated hernias where blood flow to the herniated tissue is cut off. Supporting documentation will include operative reports detailing necrotic tissue, pathology reports confirming gangrene, or physician notes describing this severe complication.

• Always confirm the presence of gangrene; do not assume it based on incarceration or strangulation alone.
• Distinguish between congenital and acquired diaphragmatic hernias if specified, though this code does not differentiate.
• Code any associated complications or underlying causes, such as intestinal obstruction, if documented.
