Corros unsp deg mult sites of unsp low limb, ex ank/ft, sqla

This code describes the long-term effects or complications resulting from a chemical burn (corrosion) that affected multiple areas of the lower limb, excluding the ankle and foot. The specific degree of the original burn is not documented, nor is the exact location on the lower limb specified beyond "multiple sites."

Use this code when documenting a patient presenting with a current condition, symptom, or complication that is a direct consequence of a past chemical burn to multiple, unspecified sites of the lower limb (excluding ankle and foot). This applies to chronic issues like scarring, contractures, or persistent pain directly attributable to the original corrosion.

• Requires a seventh character "S" to indicate sequela, meaning the patient is being seen for a complication or late effect of the original injury.
• Ensure documentation clearly links the current condition to a previous chemical burn of the lower limb, and that the burn involved multiple sites but excluded the ankle and foot.
• Avoid using this code for acute chemical burns; those require codes from the T24.0-T24.3 series with an appropriate seventh character for initial encounter, subsequent encounter, or sequela if the acute burn is the current focus.
