Pnctr w fb of right great toe w damage to nail, sequela

This code signifies a past injury to the right great toe, specifically a puncture wound that introduced a foreign object, and resulted in lasting damage to the toenail. The "sequela" indicates that the current encounter is for a complication or late effect directly attributable to this previous injury.

Apply this code when a patient presents with a chronic issue, such as nail deformity, onychomycosis, or persistent pain, that is a direct consequence of a previously sustained puncture wound with a foreign body in their right great toe. This is appropriate when the initial injury has healed, but its effects on the nail persist and require ongoing management.

• Ensure documentation clearly links the current nail damage to a prior puncture wound with a foreign body.
• The "S" seventh character indicates sequela, meaning the initial injury occurred in the past.
• Do not use this code for the initial treatment of the acute puncture wound.
