Subluxation of tarsal joint of left foot, initial encounter

This code signifies a partial dislocation of one or more of the tarsal bones in the left foot. This means the joint surfaces are no longer perfectly aligned but still maintain some contact, causing pain, swelling, and impaired function. It represents the initial episode of care for this specific injury.

Use this code for a patient presenting with a newly diagnosed subluxation of a tarsal joint in their left foot, such as a subtalar or talonavicular subluxation. This applies to the first time the patient is receiving active treatment for this specific injury, whether in an emergency department, physician's office, or hospital setting.

• Ensure documentation specifies "left foot" and "tarsal joint" to support this code.
• The "A" in the seventh character indicates an "initial encounter" for active treatment of the injury.
• Do not use this code for a complete dislocation (luxation) or for subluxations of other foot joints (e.g., metatarsal).
