Disorder of ligament, left foot

This code signifies a non-traumatic pathology affecting the ligaments of the left foot. This could include conditions such as chronic sprains, laxity, inflammation (ligamentitis), or degeneration of the fibrous connective tissues that stabilize the foot joints. It indicates a primary disorder of the ligament itself, rather than a secondary issue from a fracture or dislocation.

Apply this code when documentation specifies a diagnosed disorder of a ligament in the left foot, such as a chronic left ankle sprain, left foot ligamentous laxity, or left plantar fasciitis where the primary pathology is identified as a ligamentous disorder. Supporting documentation should clearly state the affected foot and the nature of the ligamentous pathology.

• Ensure the documentation specifies "left foot" to differentiate from other foot laterality or unspecified sites.
• Do not use this code for acute sprains or strains; those are coded with S93.4- or S93.5-.
• Distinguish between a primary ligament disorder and a ligamentous injury secondary to another condition, such as an ankle fracture.
