Corros 2nd deg mul sites of left lower limb, ex ank/ft, sqla

This code signifies a second-degree burn injury (corrosion) affecting multiple, non-contiguous areas of the left lower limb, excluding the ankle and foot. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial burn injury, occurring after the acute phase has passed.

Use this code when documenting a long-term consequence or residual effect of a second-degree chemical burn to the left thigh, knee, or calf, where multiple sites were involved. This applies to situations such as chronic pain, scarring, contractures, or non-healing ulcers directly attributable to the original corrosion.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury.
• Do not use this code for acute burn encounters; it is strictly for sequelae.
• Ensure the documentation clearly specifies "multiple sites" and excludes the ankle and foot to justify this specific code.
