This code signifies a long-term complication or residual effect stemming from a second-degree corrosion (chemical burn) that affected multiple areas of the patient's right shoulder and upper arm, excluding the wrist and hand. This indicates that the acute injury has healed, but the patient is still experiencing issues directly related to that past chemical burn.

Use this code when documenting a patient presenting with a chronic condition, scar tissue, contracture, or other persistent sequelae directly attributable to a second-degree chemical burn on the specified right upper limb regions. This applies when the original injury occurred in the past and the current encounter addresses these lasting effects.

• Ensure documentation clearly links the current condition to a past second-degree chemical burn of the right shoulder and upper limb.
• Verify that the specific sites involved (multiple sites of right shoulder and upper limb, excluding wrist/hand) are accurately reflected.
• Confirm that the encounter is for the sequela (late effect) of the burn, not the acute burn itself.
