ICD-10-CMPuncture wound without foreign body of right great toe with damage to nail, initial encounter
This code signifies a penetrating injury to the right great toe, specifically a puncture wound that does not involve a retained foreign object. The injury has also caused damage to the toenail. This code is used for the initial treatment of such an injury.
This code is appropriate when a patient presents for the first time with a puncture wound to their right great toe, and examination confirms no foreign body is present, but the toenail has sustained damage. Examples include stepping on a nail that goes through the nail and skin but does not break off, or a sharp object piercing the toe and nail.
