Disp fx of posterior process of left talus, sequela

This diagnosis code indicates a prior injury to the posterior process of the left talus, specifically a fracture that was displaced. The "sequela" designation signifies that the patient is now experiencing a late effect or complication directly resulting from this old fracture, rather than an acute injury. These late effects can include chronic pain, stiffness, limited range of motion, or post-traumatic arthritis.

Apply this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a previously sustained and healed, or non-union, displaced fracture of the posterior process of the left talus. This is appropriate for follow-up visits addressing long-term issues stemming from the original injury, not for the initial treatment of the acute fracture. It is used when the acute phase of the injury has passed, and the current encounter focuses on the residual problems.

• Always assign a secondary code to describe the specific nature of the sequela (e.g., M25.572 for chronic pain in the left ankle, M19.172 for post-traumatic arthritis of the left ankle).
• Verify documentation clearly states the fracture was "displaced" and that the current encounter addresses a "sequela" or "late effect" of a prior injury.
• Do not use this code for acute fractures; use the appropriate acute fracture code from the S92.13- series.
