This code signifies a chemical burn of an indeterminate severity affecting the shoulder or any part of the upper limb, excluding the wrist and hand, at an unspecified location. It indicates that the patient is receiving follow-up care for an injury that has already been initially treated.

Apply this code when documenting subsequent encounters for chemical burns to the upper arm or shoulder region where the specific degree of the burn or the exact site within the region is not documented. This is appropriate for office visits, wound care, or rehabilitation appointments following the initial treatment.

• Ensure the documentation clearly states "subsequent encounter" for appropriate code selection.
• Avoid using this code if the degree of corrosion (e.g., first, second, third degree) is specified in the medical record.
• Do not use this code for chemical burns of the wrist or hand; separate codes exist for those locations.
