Corrosion of first degree of unspecified palm, subs encntr

This code signifies a superficial chemical burn affecting the palm of the hand, where only the outermost layer of skin is damaged. It indicates a subsequent encounter for this injury, meaning the patient is receiving follow-up care after the initial treatment. There is no specific information available regarding which palm (left or right) was affected.

This code is appropriate for documenting follow-up visits for a first-degree chemical burn to an unspecified palm. Examples include routine wound checks, dressing changes, or re-evaluation of the injury after initial treatment. It should be used when the specific palm involved is not documented in the medical record.

• Ensure the documentation clearly states "first degree" and "corrosion" (chemical burn) to support this code.
• Verify that the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• If the laterality (left or right palm) is specified in the medical record, a more specific code should be chosen.
