Subluxation of MTP joint of unsp great toe, sequela

This code signifies a chronic or late-effect condition resulting from a previous subluxation of the metatarsophalangeal (MTP) joint of the great toe. It indicates that the joint is no longer fully dislocated but remains partially misaligned, causing ongoing symptoms or functional impairment. This residual instability or deformity is a direct consequence of the initial injury.

Use this code when documenting a patient presenting with persistent issues, such as pain, stiffness, or functional limitations, in the great toe MTP joint, which are attributed to a past subluxation. This applies to situations where the acute injury has resolved, but its long-term effects are still being managed. It is appropriate for follow-up visits addressing chronic complications.

• Always assign a secondary code to describe the specific sequela, such as chronic pain (e.g., G89.29) or degenerative arthritis (e.g., M19.071).
• Ensure documentation clearly links the current condition to a previous subluxation, even if the initial injury occurred years prior.
• Do not use this code for acute or initial subluxations; those require codes from the acute injury section.
