Open bite of right thumb with damage to nail, sequela

This code describes a healed or residual effect from an open bite injury to the right thumb, specifically involving damage to the nail or nail bed. It indicates that the initial acute injury has resolved, but there are lasting consequences such as deformity, chronic pain, or functional impairment related to the nail.

Apply this code when documenting a patient presenting with a long-term complication or sequela directly attributable to a past open bite injury of the right thumb with nail involvement. This is appropriate for follow-up visits addressing chronic issues stemming from the original trauma, rather than the acute injury itself.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., scar, chronic pain, nail deformity).
• Ensure documentation clearly links the current condition to the past open bite injury of the right thumb nail.
• Do not use this code for the initial acute injury; instead, use the appropriate acute open bite code.
