Gas gangrene

This code represents gas gangrene, a severe and rapidly progressive form of clostridial myonecrosis. It is characterized by muscle necrosis, gas production within tissues, and systemic toxicity, often leading to limb loss or death if not promptly treated.

Assign this code for documented cases of gas gangrene, typically identified by clinical signs such as crepitus, severe pain, and rapid tissue destruction, often following trauma or surgery. Documentation should clearly state "gas gangrene" or "clostridial myonecrosis" and describe the affected site.

• Ensure documentation specifies "gas gangrene" to differentiate from other forms of gangrene.
• Code any associated open wounds or injuries that served as the portal of entry for the infection.
• Always sequence this code as the principal diagnosis when it is the primary reason for the admission or encounter.
