Corrosion of unspecified degree of left palm, init encntr

This code signifies a chemical burn of the left palm where the specific depth or severity of the burn (e.g., first, second, or third degree) is not documented. It indicates damage to the skin and underlying tissues caused by corrosive substances.

This code is appropriate for initial encounters when a patient presents with a chemical burn to their left palm, and the medical record does not specify the degree of the burn. It should be used when the provider's documentation clearly states "corrosion" or "chemical burn" but omits the depth.

• Ensure the documentation explicitly states "left palm" and "corrosion" or "chemical burn."
• Only use this code for the initial treatment of the injury. Subsequent encounters will require a different seventh character.
• If the degree of the chemical burn is known, a more specific code from the T23.0-T23.3 series should be used instead.
