Nondisp dome fracture of left talus, subs for fx w malunion

This code describes a situation where the rounded upper portion of the left talus bone, which forms part of the ankle joint, has fractured but the bone fragments are still in their normal anatomical position. The patient is in a subsequent phase of care, and the fracture has healed incorrectly, resulting in a malunion.

Use this code when a patient presents for follow-up care of a previously diagnosed nondisplaced dome fracture of the left talus, and imaging or clinical assessment confirms that the fracture has healed in an abnormal alignment. This would apply to scenarios such as physical therapy for a malunited fracture, or evaluation for corrective surgery.

• Ensure documentation clearly states "nondisplaced" and specifies the "dome" of the talus.
• Verify that the encounter is "subsequent" and that "malunion" is explicitly documented as the outcome of the fracture healing.
• Laterality (left) is crucial for accurate code assignment.
