Subluxation of MTP joint of left lesser toe(s), sequela

This diagnosis code indicates a partial dislocation of the joint connecting the metatarsal bone to the phalanx bone in one or more of the left lesser toes (toes 2-5). This specific code is used when the subluxation is a long-term consequence or complication of an earlier injury or condition, rather than an acute event.

Apply this code when documentation clearly states a subluxation of the metatarsophalangeal joint of the left lesser toe(s) that is a residual effect of a previous injury or disease. This would be appropriate for chronic instability, deformity, or pain resulting from an old trauma or degenerative process affecting the joint.

• Ensure the medical record explicitly states "sequela" or indicates a chronic condition resulting from a prior injury.
• Confirm the affected joint is the metatarsophalangeal joint and the location is the left lesser toe(s).
• Do not use for acute subluxations; those would be coded with an initial or subsequent encounter character.
