Dislocation of MTP joint of left great toe, subs

This code signifies a dislocation of the joint connecting the metatarsal bone to the first bone of the left great toe. This injury involves the complete displacement of the joint surfaces. The "D" in the code indicates that this is not the initial treatment for the injury, but rather a follow-up visit during the healing or recovery phase.

This code is appropriate for encounters where a patient is receiving follow-up care for a previously diagnosed and treated dislocation of the left great toe's metatarsophalangeal joint. This includes visits for cast changes, physical therapy, monitoring healing progress, or addressing ongoing symptoms after the initial acute treatment. It should be used after the initial treatment of the injury has concluded.

• Ensure documentation clearly states "left great toe" and "metatarsophalangeal joint" to support this specific code.
• Verify that the encounter is for subsequent care, not the initial treatment, which would require an "A" or "B" seventh character.
• Always review the medical record for laterality and the specific joint involved to avoid miscoding.
