Corrosion of unspecified degree of left axilla, sequela

This code signifies a long-term complication or late effect resulting from a chemical burn (corrosion) to the left armpit area. The original burn's severity is not specified, but the code indicates that the patient is now experiencing residual issues directly attributable to that past injury.

Use this code when documenting conditions such as scarring, contractures, chronic pain, or functional limitations in the left axilla that are a direct consequence of a previously sustained chemical burn. This applies when the acute phase of the corrosion has passed, and the patient is being treated for the lasting effects.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a past chemical burn of the left axilla.
• Do not use this code for active, acute chemical burns; those require codes from the T20-T25 range without the "S" seventh character.
