ICD-10-CMNondisplaced comminuted fracture of shaft of humerus, left arm, subsequent encounter for fracture with nonunion
This code signifies a left humerus shaft fracture that is broken into multiple pieces (comminuted) but remains in its natural anatomical alignment (nondisplaced). The "subsequent encounter" indicates the patient is receiving ongoing care for the fracture, and "nonunion" specifies that the bone fragments are failing to heal together.
This code is appropriate for follow-up visits where a patient with a previously diagnosed left humerus shaft fracture is being treated for a confirmed nonunion. This includes scenarios such as surgical intervention for nonunion, casting/bracing adjustments, or medication management specifically addressing the lack of bone healing.
