Corrosion of third degree of right upper arm, sequela

This code indicates a third-degree chemical burn (corrosion) affecting the right upper arm, where the acute injury has healed and the patient is now experiencing a complication or residual effect of that past burn. Third-degree burns involve full-thickness destruction of the skin and underlying tissues.

Apply this code when documenting a patient presenting with a long-term complication, such as scarring, contracture, chronic pain, or functional impairment, directly attributable to a previously sustained third-degree chemical burn of the right upper arm. This code is used after the initial healing phase of the acute injury.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a past third-degree chemical burn of the right upper arm.
• Verify the laterality (right) and anatomical site (upper arm) are precisely documented.
