Tox eff of corrosv alkalis and alk-like substnc, asslt, sqla

This code signifies a long-term or residual health problem resulting from a corrosive alkali or alkali-like substance exposure that occurred due to an assault. These substances cause severe chemical burns and tissue damage, and the sequelae can include scarring, strictures, organ dysfunction, or chronic pain.

Apply this code when documenting a current condition that is a direct consequence of a past assault involving corrosive alkalis, such as lye or drain cleaner. This is appropriate for follow-up visits addressing chronic issues like esophageal strictures or skin disfigurement stemming from the initial injury.

• Always use in conjunction with a code describing the specific sequela (e.g., esophageal stricture, scar).
• Ensure documentation clearly links the current condition to a past assault by a corrosive alkali.
• This code is for the sequela of the toxic effect, not the initial acute poisoning.
