Abrasion of unspecified thumb, subsequent encounter

This code signifies a superficial injury to the thumb, characterized by the scraping or rubbing off of the outer layer of skin, without specifying which thumb was affected. It indicates that the patient is receiving follow-up care for an abrasion that was previously treated.

Apply this code when a patient presents for a subsequent visit related to an abrasion of an unspecified thumb, such as for wound check, dressing change, or monitoring healing progress. This code is appropriate after the initial treatment of the abrasion has already been coded.

• Ensure documentation clearly indicates a subsequent encounter for the abrasion.
• Verify that the abrasion is indeed of the thumb and not another digit.
• If the specific thumb (right or left) is documented, a more specific code should be used.
