Laceration w/o fb of left thumb w damage to nail, sequela

This code signifies a past injury to the left thumb involving a laceration that did not include a foreign body, and which specifically resulted in damage to the nail structure. The "sequela" designation indicates that this code is used to report the late effects or complications of that initial injury, rather than the acute event itself.

Apply this code when documenting a patient presenting with ongoing issues, deformities, or functional limitations of the left thumb nail directly attributable to a previously sustained laceration. This would include conditions like nail dystrophy, permanent nail plate changes, or chronic pain related to the nail bed damage from the original injury.

• Ensure documentation clearly states the injury is a sequela and not an acute laceration.
• Verify the laterality is specifically the left thumb.
• Confirm the absence of a foreign body in the original laceration.
