Contracture, unspecified ankle

This code signifies a persistent limitation in the range of motion of an ankle joint, where the specific cause or type of contracture is not documented. It indicates a fixed resistance to passive stretching, leading to restricted movement of the ankle.

Apply this code when documentation clearly states an ankle contracture but lacks further specificity regarding its etiology (e.g., post-traumatic, inflammatory, neurological). This code is appropriate when the physician's assessment identifies a contracture of the ankle, and no more precise ICD-10-CM code is available based on the provided clinical details.

• Always seek further specificity from the provider if the documentation only states "ankle contracture" to determine if a more precise code exists.
• Do not use this code if the documentation specifies the type of contracture (e.g., M24.571 for right ankle, M24.572 for left ankle, or a more specific code if the cause is known).
• Ensure the laterality is not specified in the documentation, as this code is for an "unspecified ankle." If laterality is known, use M24.571 or M24.572.
