Subluxation of tarsometatarsal joint of unsp foot, sequela

This code describes a chronic or residual condition resulting from a previous subluxation (partial dislocation) of one of the tarsometatarsal joints in an unspecified foot. This indicates ongoing issues or long-term effects stemming from the original injury, rather than the acute event itself.

Use this code when documenting a patient presenting with persistent pain, instability, or functional limitations in the midfoot that are directly attributable to a prior tarsometatarsal joint subluxation. This is appropriate for follow-up encounters addressing the long-term sequelae after the initial injury has healed to its maximum medical improvement.

• Always use this code as a secondary diagnosis following a primary code describing the specific sequela (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to a past tarsometatarsal subluxation.
• Avoid using this code for acute or initial injury encounters; those require codes from the acute injury chapter.
