Oth fracture of left lesser toe(s), subs for fx w nonunion

This code signifies a left lesser toe fracture, excluding the great toe, that has failed to heal properly and is currently under active treatment. The "nonunion" aspect indicates that the bone ends have not united and are not expected to without further intervention, such as surgery. This represents a chronic and complicated stage of fracture healing.

This code is appropriate for documenting ongoing care for a patient whose left lesser toe fracture has been diagnosed with nonunion. It applies when the patient is receiving treatment, such as casting, bracing, or surgical planning, specifically addressing the nonunion. This code would be used for follow-up visits after the initial injury and diagnosis of nonunion.

• Ensure documentation clearly states "nonunion" and specifies the left lesser toe(s).
• Verify the encounter is for subsequent care related to the fracture, not the initial injury.
• Distinguish from malunion, which implies healing in an incorrect position, versus a complete failure to heal.
