This code indicates a long-term complication or late effect resulting from a corrosive burn affecting multiple areas of the right shoulder and upper limb, excluding the wrist and hand. The specific degree of the original burn is not documented or is unknown.

Apply this code when documenting a patient presenting with a current condition or sequela (e.g., scarring, contracture, chronic pain, functional impairment) directly attributable to a corrosive burn that occurred in the past. This is appropriate when the initial burn involved multiple sites on the right shoulder and upper limb, and the acute phase of the injury has resolved.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, contracture).
• Ensure the documentation clearly links the current condition to a past corrosive burn of the specified anatomical sites.
• Do not use this code for acute corrosive burns; instead, use the appropriate T22.x codes for initial encounters.
