Nondisplaced trimalleolar fracture of r low leg, sequela

This code signifies a past injury involving a trimalleolar fracture of the right lower leg that has since healed, but the patient is now experiencing a complication or residual effect directly attributable to that prior fracture. A trimalleolar fracture involves the medial, lateral, and posterior malleoli of the ankle. The "nondisplaced" aspect indicates the bone fragments did not significantly shift out of alignment at the time of the original injury.

Apply this code when documenting a patient encounter for a long-term complication or sequela arising from a previously sustained, nondisplaced trimalleolar fracture of the right lower leg. This includes conditions such as chronic pain, post-traumatic arthritis, malunion, nonunion, or persistent instability directly linked to the old fracture. It should be used when the acute phase of the fracture has passed, and the patient is being treated for the lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M19.171 for post-traumatic arthritis of the right ankle).
• Ensure documentation clearly links the current condition to the previous nondisplaced trimalleolar fracture of the right lower leg.
• Verify that the fracture was indeed nondisplaced and involved the right lower leg to ensure accurate code selection.
