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

This code signifies a long-term consequence or late effect of an open wound on an unspecified great toe, where the wound itself was not fully characterized (e.g., puncture, laceration) and the nail was also damaged. It indicates that the initial injury has healed, but residual issues related to the wound and nail damage persist.

Apply this code when documenting a patient presenting for treatment of a sequela (e.g., chronic pain, deformity, non-healing ulcer, nail dystrophy) resulting from a previously sustained, unspecified open wound to the great toe that also involved nail damage. This code is appropriate when the initial injury occurred in the past and the current encounter addresses its lasting effects.

• This "S" seventh character indicates a sequela, meaning the initial injury has healed and the current encounter addresses a complication or residual effect.
• Ensure documentation clearly supports that the current condition is a direct result of a past open wound to the great toe with nail involvement.
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code with the "A" (initial encounter) or "D" (subsequent encounter) seventh character.
