Nondisp oth extrartic fx l calcaneus, subs for fx w nonunion

This code signifies a fracture of the left calcaneus (heel bone) that is located outside of a joint and has not shifted from its normal position. The "subsequent encounter with nonunion" indicates that the patient is receiving ongoing care for this fracture, and it has failed to heal properly.

This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed, nondisplaced, extraarticular left calcaneal fracture that has not united. This includes evaluations for non-surgical management of nonunion, or prior to surgical intervention for the nonunion.

• Ensure documentation clearly specifies "nonunion" for the subsequent encounter.
• Verify the fracture is extraarticular and nondisplaced.
• Confirm the laterality is explicitly documented as "left."
