Corrosion of unsp deg mult sites of unsp wrs/hnd, sequela

This code signifies a long-term complication or late effect resulting from a chemical burn (corrosion) affecting multiple, unspecified areas of the wrist and hand. The original injury's severity is not specified, and the current condition is a residual problem rather than the acute injury itself.

Use this code when documenting a patient presenting with a chronic issue, such as scarring, contracture, or nerve damage, that is directly attributable to a past chemical burn on their wrist and hand. This applies when the specific degree of the original burn and the exact sites on the wrist and hand are not precisely documented or are generalized.

• Always append the "S" for sequela when the patient is being treated for the residual effects of a past injury.
• Avoid using this code for acute chemical burns; instead, use the appropriate acute corrosion codes.
• Ensure documentation clearly links the current condition to a previous chemical burn of the wrist and hand.
