Corrosion of unsp degree of back of unsp hand, sequela

This code signifies a long-term complication or late effect resulting from a chemical burn (corrosion) on the back of an unspecified hand. The original burn's severity is not documented, and the specific hand involved is also unknown. This diagnosis indicates that the patient is experiencing residual issues from a past corrosive injury.

Apply this code when documenting a patient presenting with a chronic condition, scar, contracture, or other lasting sequela directly attributable to a chemical burn on the back of the hand, where the initial burn's degree was not specified and the laterality is unknown. This is used after the acute phase of the injury has passed.

• Always assign a sequela code when the patient is being treated for the residual effects of a past injury, not the acute injury itself.
• Ensure documentation clearly links the current condition to a previous corrosive burn on the back of the hand.
• If the degree of corrosion or laterality is known, a more specific sequela code should be chosen.
