Corros unsp deg of shldr/up lmb, ex wrs/hnd, unsp site, sqla

This code signifies a long-term complication or late effect resulting from a chemical burn (corrosion) to the shoulder or upper arm, excluding the wrist and hand. The original injury's severity and specific location within this region are not specified, and the current condition is a sequela of that past event.

Use this code when documenting a patient presenting with a chronic issue, such as scarring, contracture, or chronic pain, that is directly attributable to a chemical burn sustained in the shoulder or upper limb (excluding wrist/hand) in the past. This applies when the acute phase of the original corrosion has resolved, and the current treatment addresses the residual effects.

• Always sequence this code after the code for the specific sequela (e.g., scar, contracture) if applicable.
• Ensure documentation clearly links the current condition to a past chemical burn of the specified anatomical area.
• Avoid using this code for acute chemical burns; those require codes from the T20-T25 range without the "S" seventh character.
