Corrosion of unspecified degree of right forearm, sequela

This code signifies a long-term complication or late effect resulting from a chemical burn (corrosion) of an unspecified degree affecting the patient's right forearm. It indicates that the acute phase of the injury has passed, and the current condition is a residual problem directly attributable to the original corrosion.

Use this code when documenting a chronic scar, contracture, nerve damage, or other persistent issue on the right forearm that is a direct consequence of a past chemical burn. This applies when the original burn is no longer active or being treated, but its lasting impact is the focus of the current encounter.

• Always sequence this code after the code describing the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a previous chemical burn of the right forearm.
• Do not use this code for active or acute chemical burns; use the appropriate T22.0-T22.3 codes for those situations.
