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

This code signifies a fracture of an unspecified toe or toes on the left foot that has failed to heal properly, indicating a nonunion. The patient is presenting for follow-up care related to this persistent fracture.

This code is appropriate for documenting ongoing management of a left toe fracture where imaging or clinical assessment confirms that the bone fragments have not united. It should be used for subsequent visits after the initial treatment, when the nonunion is the primary focus of the encounter.

• Ensure documentation clearly specifies "left" toe(s) and "nonunion" for accurate code assignment.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use if the specific toe (e.g., great toe, lesser toe) is documented; more specific codes exist for those scenarios.
