Contusion of left great toe with damage to nail, sequela

This code signifies a persistent or late-developing complication stemming from a past contusion (bruise) to the great toe on the left foot, specifically involving damage to the toenail. This could manifest as chronic nail deformity, discoloration, onycholysis, or other long-term issues directly attributable to the initial injury.

Apply this code when documenting a patient presenting with a current, ongoing problem of the left great toenail that is a direct consequence of a previously sustained contusion. This is appropriate for follow-up visits where the initial injury has healed, but the nail damage persists as a sequela.

• Ensure documentation clearly links the current nail damage to a past great toe contusion.
• Do not use for acute injuries; this code is specifically for sequelae (late effects).
• Consider additional codes for any associated infections or other current conditions.
