Pnctr w fb of right thumb w damage to nail, sequela

This code describes a long-term complication or late effect resulting from a penetrating injury to the right thumb, specifically involving a foreign object that has also caused damage to the nail. The injury is no longer in its acute phase but is presenting with residual issues.

Apply this code when documenting a patient presenting for treatment of a sequela (e.g., chronic pain, deformity, infection, non-healing wound) directly attributable to a past puncture wound of the right thumb with a foreign body and associated nail damage. This code is appropriate when the initial injury has healed, but its lasting effects require ongoing medical attention.

• Always assign a sequela code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past puncture wound and nail damage.
• Verify the laterality (right thumb) and the presence of both a foreign body and nail damage in the patient's history.
