This code describes the long-term effects or complications arising from a third-degree chemical burn affecting multiple areas of the patient's right shoulder and upper arm, excluding the wrist and hand. These sequelae could include chronic pain, scarring, contractures, or functional limitations that persist after the acute injury has healed.

Use this code when documenting a patient presenting with residual conditions directly attributable to a past third-degree chemical burn on the specified right upper limb regions. This applies when the initial injury is no longer acute and the focus of care is on managing the lasting consequences.

• Always assign this "S" code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the previous third-degree chemical burn of the right shoulder/upper limb.
• Verify that the burn was indeed chemical (corrosion) and not thermal, and that it was third degree.
