Contusion of unsp great toe with damage to nail, sequela

This code describes a long-term effect or complication resulting from an initial bruise to an unspecified great toe, specifically involving damage to the toenail. This indicates that the original injury has healed, but residual issues related to the nail persist.

Apply this code when documenting a patient presenting with ongoing nail deformities, discoloration, or other chronic issues on the great toe that are directly attributable to a past contusion. This is appropriate for follow-up visits addressing these persistent sequelae, not the initial acute injury.

• Ensure documentation clearly links the current nail damage to a previous great toe contusion.
• This "S" seventh character indicates sequela, meaning it's used for complications or conditions arising as a direct result of a previous injury, after the acute phase has passed.
• Avoid using this code for acute contusions; instead, use the appropriate acute injury code.
