Corrosions involving less than 10% of body surface

This code signifies a chemical burn, also known as a corrosion, affecting a small portion of the patient's total body surface area. The injury is caused by contact with a corrosive substance, leading to tissue damage. The severity of the burn is not specified by this code, only the extent of body involvement.

Use this code for patients presenting with chemical burns covering less than 10% of their body. This includes localized corrosions from household chemicals, industrial agents, or other caustic substances. It is appropriate for initial encounters and subsequent care related to the acute injury.

• Always code the specific corrosive agent using an external cause code (e.g., T51-T65) in conjunction with this code.
• Do not use this code for thermal burns; refer to the T20-T31 series for those injuries.
• Further specify the site of the corrosion using a more detailed T20-T25 code if the burn is to a specific body part (e.g., T20.6 for corrosion of head, face, and neck).
