Abrasion of lip, subsequent encounter

This code signifies a superficial injury to the lip, characterized by a scrape or rub that removes the outer layer of skin, occurring during a follow-up visit for initial treatment. It indicates that the patient is receiving continuing care for a previously diagnosed lip abrasion, rather than presenting with a new injury.

Apply this code when a patient returns for subsequent evaluation or treatment of an abrasion to the lip, such as wound care, monitoring for healing, or addressing minor complications. Documentation should clearly state "subsequent encounter" or indicate follow-up care for a previously treated lip abrasion.

• Ensure the "D" seventh character is appropriate for subsequent care; "A" is for initial encounter, "S" for sequela.
• Distinguish from open wounds (lacerations) of the lip, which involve deeper tissue disruption.
• Verify laterality if specified in the documentation, though S00.511 is for unspecified lip.
