Nondisplaced fracture of the posterior process of the right talus, subsequent encounter for fracture with nonunion. This code indicates a follow-up visit for a patient who previously experienced a nondisplaced fracture of the posterior process of their right talus and the fracture has failed to heal, resulting in nonunion.

Example 1: A patient initially presented with a nondisplaced fracture of the posterior process of the right talus six weeks ago. They return for a follow-up appointment, and imaging reveals the fracture has not healed and is now considered a nonunion., A patient with a history of a nondisplaced fracture of the posterior process of the right talus is experiencing persistent pain and instability. Upon examination and imaging, it is determined that the fracture has failed to unite, and surgical intervention may be required., A patient who sustained a nondisplaced fracture of the posterior process of the right talus several months prior is experiencing ongoing discomfort and limited mobility. They consult with an orthopedist who confirms nonunion of the fracture through physical examination and radiographic findings.
