Corros 3rd deg mu sites of right lower limb, ex ank/ft, sqla

This code describes a severe, full-thickness skin injury affecting multiple areas of the right lower limb, excluding the ankle and foot, caused by corrosive substances. The corrosion has progressed to the deepest layers of the skin, indicating significant tissue damage. The "sequela" designation indicates this code is used for complications or conditions arising from the initial injury, not the acute event itself.

Use this code when documenting long-term effects, scars, or ongoing treatment related to a third-degree corrosive injury that occurred on multiple sites of the right lower limb (excluding ankle/foot). This would apply in follow-up visits for wound care, skin grafting, or management of chronic pain/disfigurement resulting from the initial burn. It is not for the initial encounter of the acute corrosive burn.

• Always use in conjunction with an external cause code (V00-Y99) to specify the circumstances of the injury.
• Ensure the laterality (right lower limb) and anatomical specificity (excluding ankle and foot) are accurately reflected in the patient's documentation.
• The "S" seventh character indicates sequela; ensure the encounter is for a late effect or complication of the original injury.
