Burn third deg of unsp site left lower limb, ex ank/ft, sqla

This code signifies a third-degree burn on the left lower limb, excluding the ankle and foot, where the acute injury has healed and the patient is now experiencing long-term complications or effects. These sequelae can include scarring, contractures, chronic pain, or functional impairment resulting from the original severe burn.

Use this code when documenting follow-up care for a patient whose third-degree burn on the left lower limb (e.g., thigh, knee, calf) has resolved, but they are presenting with residual conditions directly attributable to that burn. This applies to situations where the primary focus of the encounter is managing the lasting impact of the burn, not the acute burn itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., L90.5 for scar, M24.5 for contracture).
• Ensure documentation clearly links the current condition to the previous third-degree burn on the specified anatomical site.
• The "S" seventh character indicates sequela and should only be used for complications or conditions arising after the acute phase of the burn has passed.
