Displaced fracture of neck of left talus, sequela

This code signifies a past fracture of the neck of the left talus that was displaced, and the patient is now experiencing a long-term complication or residual effect directly related to that previous injury. These sequelae can include chronic pain, nonunion, malunion, degenerative arthritis, or persistent functional limitations. The original fracture has healed, but its lasting impact is still present.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a previously sustained and healed displaced fracture of the neck of the left talus. This is appropriate for follow-up encounters where the focus is on managing the chronic effects, rather than the acute treatment of the initial fracture. Examples include chronic ankle instability or post-traumatic arthritis stemming from the old injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M19.172 for post-traumatic arthritis).
• Ensure documentation clearly links the current condition to the previous displaced fracture of the left talus neck.
• The "S" seventh character indicates sequela and should only be used for complications or conditions arising as a direct result of a healed injury.
