Subluxation of MTP joint of unsp great toe, init

This code signifies a partial dislocation of the joint connecting the metatarsal bone to the phalanx of the great toe, where the joint surfaces are still in partial contact. It specifically refers to the initial presentation or treatment of this injury.

Apply this code for patients presenting with a newly diagnosed or first-time treatment for a subluxation of the metatarsophalangeal joint of the great toe, when the affected side (left or right) is not documented. This often occurs due to trauma or repetitive stress.

• Ensure documentation clearly states "subluxation" and not a full "dislocation" (which would be a different code series).
• Only use this code when the laterality (left or right) of the great toe is unspecified in the medical record.
• The "A"第七 character indicates an initial encounter for active treatment of the injury.
