Corrosion of third degree of right toe(s) (nail), sequela

This code describes a severe chemical burn affecting the right toe(s) or toenail, characterized by full-thickness tissue destruction. This type of injury involves damage through all layers of the skin, potentially extending to underlying tissues, and is documented as a long-term complication or late effect of the initial corrosion.

Use this code for patients presenting with residual problems or chronic conditions directly resulting from a third-degree chemical burn to the right toe(s) or toenail, where the acute phase of the injury has passed. This includes scarring, contractures, chronic pain, or other persistent issues attributable to the original corrosive exposure.

• Assign this code only when the "S" seventh character is appropriate, indicating a sequela or late effect.
• Ensure documentation clearly specifies the right toe(s) or nail and confirms a third-degree chemical burn.
• Do not use for acute chemical burns; those require codes from the T25.73- series without the "S" seventh character.
