Other enthesopathy of left foot and ankle

This code signifies a painful degenerative or inflammatory condition affecting the entheses (sites where tendons, ligaments, or joint capsules attach to bone) in the left foot or ankle, excluding the Achilles tendon. It indicates a non-specific enthesopathy that is not classified elsewhere.

Apply this code when documentation specifies enthesopathy of the left foot or ankle, and a more specific diagnosis (e.g., Achilles tendinitis) is not provided. Supporting documentation should include a physician's diagnosis of enthesopathy and laterality (left foot/ankle).

• Ensure the documentation clearly specifies "left" foot and/or ankle.
• Differentiate from M77.32 (Calcaneal spur, left foot), which is a specific type of enthesopathy.
• Always review for more specific enthesopathy codes (e.g., M76.62 for Achilles tendinitis, left) before assigning this general code.
