Corros 2nd deg mul sites of shldr/up lmb, ex wrs/hnd, sqla

This code signifies a second-degree chemical burn affecting multiple areas of the shoulder and upper limb, excluding the wrist and hand, where the acute injury has healed and residual effects or complications are being treated. These sequelae could include scarring, contractures, or chronic pain resulting from the initial corrosive injury.

Apply this code when documenting follow-up care for a patient experiencing long-term consequences from a second-degree chemical burn to the specified upper limb regions. This would be appropriate for conditions like scar revision, physical therapy for range of motion limitations, or management of persistent neuropathic pain directly attributable to the past corrosive injury.

• Always use this code as a secondary diagnosis, following a code for the specific sequela being treated.
• Ensure the documentation clearly specifies "second degree" and "multiple sites" within the shoulder and upper limb (excluding wrist/hand).
• Verify that the encounter is for the sequela of the burn, not the acute burn itself.
