Burn 3rd deg mu sites of shldr/up lmb, except wrs/hnd, sqla

This code signifies a third-degree burn affecting multiple areas of the shoulder and/or upper limb (excluding the wrist and hand), where the acute injury has healed and the patient is now presenting for treatment of a complication or late effect of that burn. These sequelae could include scarring, contractures, chronic pain, or other long-term issues resulting from the original severe burn.

Apply this code when documenting follow-up care for a patient who previously sustained a full-thickness burn to multiple sites of the shoulder and/or upper limb (excluding wrist/hand), and the current encounter addresses a residual condition directly attributable to that burn. Examples include surgical revision of burn scars, physical therapy for burn-related contractures, or management of chronic neuropathic pain post-burn.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to the historical third-degree burn of the specified anatomical sites.
• Verify that the burn is indeed a "sequela" (S) and not an active burn (A, D, or S for initial, subsequent, or sequela, respectively, for the burn itself).
