Nondisp fx of post pro of r talus, subs for fx w malunion

This code signifies a fracture of the posterior process of the right talus that has not shifted from its original position, but is now healing incorrectly. This malunion indicates that the bone fragments have united in an abnormal anatomical alignment, potentially leading to functional impairment or pain.

Apply this code when documenting follow-up care for a patient whose previously diagnosed nondisplaced posterior process talus fracture on the right side is now exhibiting signs of malunion. This would typically be used after initial treatment and when the physician is addressing complications related to the improper healing of the fracture.

• Ensure documentation clearly specifies "right talus" and "posterior process" to support this specific anatomical site.
• Verify the "nondisplaced" nature of the original fracture and the current presence of "malunion" during the subsequent encounter.
• This code is for a subsequent encounter, meaning it should not be used for the initial diagnosis or active treatment of the acute fracture.
