Abrasion of right thumb, subsequent encounter

This code signifies a superficial injury to the outer layer of skin on the right thumb, specifically an abrasion, that is being treated during a follow-up visit. It indicates that the initial injury has already been assessed and this encounter is for ongoing care, such as wound checks or dressing changes.

Apply this code when a patient presents for a subsequent visit related to an abrasion of their right thumb. This includes scenarios where the patient is returning for wound re-evaluation, to have dressings changed, or for monitoring of healing progress after the initial treatment.

• Ensure the encounter is truly "subsequent" and not the initial treatment for the abrasion.
• Verify the laterality is specifically the "right thumb."
• Do not use for open wounds extending beyond the epidermis or for more severe injuries.
