This code signifies a superficial burn (first-degree corrosion) affecting multiple areas of the right shoulder and upper arm, excluding the wrist and hand. It indicates that the patient is receiving follow-up care for this injury after the initial treatment.

Apply this code when documenting subsequent encounters for a patient presenting with a first-degree chemical burn to the right shoulder and/or upper arm. This is appropriate for office visits, wound care, or other follow-up appointments related to the initial corrosion.

• Ensure the documentation clearly specifies "first-degree" and "multiple sites" within the right shoulder/upper limb region.
• Verify that the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• Confirm the injury is due to a corrosive substance, not heat or electricity, to differentiate from thermal burns.
