Corrosion of unspecified degree of left upper arm, sequela

This code signifies a long-term complication or late effect resulting from a chemical burn or corrosion injury to the left upper arm, where the original degree of the burn is not specified. It indicates that the acute phase of the injury has passed, but the patient is still experiencing residual effects such as scarring, contracture, or chronic pain directly attributable to the past corrosive exposure.

Use this code when documenting a patient presenting for treatment of a persistent issue in their left upper arm that is a direct consequence of a previous corrosive injury. This applies to follow-up visits for scar revision, management of chronic pain, or treatment of functional limitations that developed after the initial burn healed.

• Always sequence this code after the code(s) identifying the specific nature of the sequela (e.g., scar, contracture).
• Do not use this code for acute corrosive injuries; it is exclusively for late effects.
• Ensure documentation clearly links the current condition to a past corrosive burn of the left upper arm.
