Contusion of right great toe with damage to nail, sequela

This code signifies a bruise to the right great toe, specifically involving injury to the toenail, where the effects of the original injury are now considered a sequela. This means the initial trauma occurred in the past, and the current encounter addresses a residual condition or complication stemming from that original contusion and nail damage.

This code is appropriate for follow-up encounters where a patient presents with ongoing issues related to a previous contusion of the right great toe with nail damage. Examples include chronic nail deformity, persistent pain, or recurrent infection directly attributable to the past injury. It should be used when the acute phase of the injury has passed, and the current treatment addresses a long-term consequence.

• Always use an external cause code (e.g., W00-Y38) to describe the circumstances of the original injury, if known.
• Ensure documentation clearly states that the current condition is a sequela of a past contusion and nail damage, not an acute injury.
• Do not use this code for initial or acute injury encounters; instead, use the appropriate acute contusion code.
