Open bite of unspecified toe(s) with damage to nail, sequela

This code signifies a healed injury to an unspecified toe, resulting from an open bite, where the nail was damaged. The "sequela" indicates that this code is used for the long-term effects or complications of the original injury, not the acute event itself. This could include nail deformities, chronic pain, or other persistent issues related to the initial bite.

Apply this code when documenting follow-up care for a patient who previously sustained an open bite to an unspecified toe, and the bite caused damage to the nail. This is appropriate for conditions like a permanently disfigured nail, chronic onychomycosis secondary to the trauma, or persistent pain at the site of the old injury. Do not use for the initial treatment of the acute bite.

• Requires an additional code to specify the exact sequela, if known (e.g., a code for nail dystrophy).
• Ensure documentation clearly states the injury was an "open bite" and involved "nail damage" to an unspecified toe.
• The "S" seventh character indicates this is a sequela, meaning it's for conditions arising from the initial injury after the acute phase has passed.
