Laceration w fb of finger w damage to nail, sequela

This code describes a past injury to a finger, excluding the thumb, where the skin was torn (lacerated) and a foreign object was embedded. Crucially, the injury also involved damage to the fingernail or nail bed, and the patient is now presenting with a long-term complication or residual effect of that original trauma.

This code is appropriate when documenting a patient presenting with a sequela (e.g., chronic pain, deformity, non-healing wound, nail dystrophy) resulting from a previously sustained laceration of a finger (not the thumb) that included a foreign body and associated nail damage. This would be used in follow-up encounters long after the initial acute injury has been treated.

• Ensure the documentation clearly indicates the current condition is a residual effect of a past injury, not an acute event.
• Verify the injury involved a finger other than the thumb and specifically mentions both a foreign body and damage to the nail.
• Always sequence this sequela code first, followed by any additional codes describing the specific nature of the sequela.
