Dislocation of MTP joint of unsp great toe, subs

This code signifies a dislocation of the joint connecting the metatarsal bone to the phalanx of the great toe, where the specific great toe (left or right) is not documented. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

Apply this code when a patient presents for subsequent treatment, such as cast changes, physical therapy, or re-evaluation of a previously diagnosed and treated metatarsophalangeal joint dislocation of the great toe, and the medical record does not specify which great toe was affected. This is appropriate for encounters occurring after the initial acute care of the injury.

• Requires a seventh character "D" for subsequent encounter.
• Only use when the specific great toe (left or right) is not documented in the medical record.
• Always sequence this code after any applicable external cause codes.
