Disp fx of proximal phalanx of unsp great toe, sequela

This code signifies a past injury involving a break in the bone of the great toe's proximal phalanx, which was displaced at the time of the original fracture. The "sequela" designation indicates that this code is used to report conditions or complications that are the direct result of that previous fracture, even if the fracture itself has healed.

This code is appropriate when a patient presents with a current condition, such as chronic pain, deformity, nonunion, malunion, or arthritis, that is directly attributable to a previously displaced fracture of the proximal phalanx of an unspecified great toe. It should be used after the initial healing phase of the acute fracture has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M20.2X- for hallux rigidus).
• Ensure documentation clearly links the current condition to the prior displaced fracture of the great toe's proximal phalanx.
• The "S" at the end indicates "sequela," meaning it's for late effects or complications of the injury.
