This code signifies a chemical burn (corrosion) affecting multiple areas of the left shoulder and upper arm, excluding the wrist and hand. The severity of the burn is not specified, indicating that the degree of tissue damage is unknown or not documented. This code is used for encounters following the initial treatment of the injury.

Use this code for follow-up visits, subsequent care, or during the healing phase of a chemical burn to multiple sites of the left shoulder and upper limb. This includes scenarios such as wound checks, dressing changes, or physical therapy appointments related to the initial corrosion injury.

• Ensure documentation clearly states "corrosion" or "chemical burn" and specifies multiple sites on the left shoulder and upper limb.
• Confirm that the encounter is for subsequent care, not the initial treatment of the burn.
• If the degree of the burn is known and documented, a more specific code should be used.
