Deep necrosis of underlying tissues [deep third degree] with loss of a body part, of multiple specified sites

This code signifies a severe burn injury characterized by full-thickness tissue destruction extending into subcutaneous tissue, muscle, or bone, accompanied by the complete loss of a body part. This deep necrosis affects multiple distinct anatomical locations.

Apply this code when documentation clearly indicates a third-degree burn with tissue destruction reaching deep structures (e.g., muscle, bone) and the subsequent loss of an entire body part (e.g., a digit, limb segment) due to the burn injury. This is typically seen in catastrophic burn cases affecting multiple sites.

• Ensure documentation explicitly states "loss of a body part" in addition to deep necrosis.
• Distinguish from codes for deep necrosis without body part loss or superficial burns.
• Sequence this code after any acute burn codes, if applicable, to reflect the severity and sequelae.
