ICD-10-CMNondisplaced fracture (avulsion) of lateral epicondyle of left humerus, subsequent encounter for fracture with delayed healing
This code signifies a non-displaced avulsion fracture of the lateral epicondyle of the left humerus that is not healing at the expected rate. An avulsion fracture occurs when a small piece of bone is pulled away from the main bone by a tendon or ligament. "Delayed healing" indicates the fracture has not united within the typical timeframe for this type of injury.
Use this code for follow-up encounters where a patient with a previously diagnosed non-displaced avulsion fracture of the left humeral lateral epicondyle is still undergoing treatment, and the physician documents that the healing process is prolonged or slower than anticipated. This code is appropriate when the fracture has not yet fully consolidated but is not considered a nonunion.
