Corrosion of third degree of unspecified axilla, sequela

This code signifies a third-degree chemical burn (corrosion) affecting an unspecified axilla, where the injury has healed but is still causing ongoing problems or complications. Third-degree burns involve full-thickness skin destruction, often leading to scarring, contractures, or nerve damage.

Use this code when documenting a patient presenting with a long-term complication or residual effect directly attributable to a past third-degree chemical burn of the axilla. This includes scenarios such as scar revision, chronic pain, or functional impairment resulting from the original injury.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the corrosion.
• Ensure the "S" seventh character is used only for sequelae, indicating a complication or condition arising from a healed injury.
• Do not use this code for acute or active third-degree chemical burns; use the appropriate acute corrosion code instead.
