Unsp open wound of right great toe w damage to nail, sequela

This code signifies a long-term or late effect of an open wound on the right great toe, where the wound's initial injury also involved damage to the toenail. It indicates that the patient is presenting for care related to the residual problems or complications stemming from this past injury, rather than the acute injury itself.

This code is appropriate for encounters addressing sequelae such as chronic pain, deformity, non-healing ulceration, or persistent nail abnormalities (e.g., onychodystrophy, ingrown nail) that are directly attributable to a previously sustained open wound of the right great toe with nail damage. It should be used when the acute phase of the original injury has passed.

• Always assign an additional code to specify the nature of the sequela (e.g., chronic pain, deformity).
• Ensure documentation clearly links the current condition to the past open wound and nail damage.
• Do not use this code for initial or subsequent encounters for the acute injury; those require codes from the acute injury chapters.
