Lacerat extensor musc/fasc/tend thmb at wrs/hnd lv, sequela

This code signifies a chronic or late-effect injury involving a laceration to the extensor muscle, fascia, and/or tendon of an unspecified thumb. The injury occurred at the wrist or hand level and is no longer in its acute phase, indicating ongoing issues or complications from the original trauma.

Use this code when documenting a patient presenting with a sequela (e.g., chronic pain, stiffness, limited range of motion, or functional impairment) directly attributable to a past laceration of the thumb's extensor structures. This applies when the initial injury has healed, but its long-term effects are being treated or evaluated.

• Ensure the documentation clearly states the injury is a "sequela" or "late effect" and not an acute injury.
• Verify the laceration specifically involves the extensor muscle, fascia, or tendon of the thumb.
• Confirm the injury location is at the wrist or hand level.
