Subluxation of MTP joint of left great toe, subs

This code signifies a partial dislocation of the metatarsophalangeal (MTP) joint of the left great toe (hallux) that has occurred previously and is now being addressed in a subsequent encounter. It indicates that the joint surfaces are no longer in full apposition but remain in partial contact.

Use this code for follow-up visits related to a previously diagnosed subluxation of the left great toe MTP joint. This includes encounters for ongoing treatment, physical therapy, re-evaluation, or monitoring after initial management. It is appropriate when the patient is no longer in the active phase of initial treatment.

• Ensure the documentation clearly specifies "left great toe" and "metatarsophalangeal joint."
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the subluxation.
• Distinguish from a sprain (S93.4-) or a complete dislocation (S93.12-) of the same joint.
