S91.212S
ICD-10-CMLaceration without foreign body of left great toe with damage to nail, sequela
This code signifies a past injury to the left great toe, specifically a laceration that did not involve a foreign body, and resulted in damage to the toenail. The "sequela" designation indicates that this code is used to report a condition that is a late effect or complication of the initial injury, rather than the acute injury itself.
This code is appropriate when documenting a patient presenting with a chronic issue or complication directly stemming from a previously sustained laceration to the left great toe that affected the nail. Examples include ongoing nail deformity, chronic pain, or recurrent infection at the site of the old injury. It should not be used for the initial acute injury.
