Corros second deg of head, face, and neck, unsp site, sqla

This code indicates a healed or residual scar, contracture, or other long-term effect resulting from a second-degree chemical burn to an unspecified area of the head, face, or neck. It signifies that the acute injury has resolved, but permanent tissue damage or functional impairment persists.

Use this code when documenting the late effects of a second-degree chemical burn to the head, face, or neck, after the initial healing phase is complete. This applies to situations where the patient is being treated for complications or sequelae directly attributable to the past burn, such as scar revision or management of chronic pain.

• Always use this code with an external cause code (V00-Y99) to identify the circumstances of the original injury, if known.
• Do not use this code for active, acute second-degree chemical burns; instead, use the appropriate T20.2- code.
• Ensure documentation clearly links the current condition to the previous second-degree chemical burn of the head, face, or neck.
