ICD-10-CMDisplaced fracture (avulsion) of medial epicondyle of left humerus, subsequent encounter for fracture with delayed healing
This code signifies a fracture where a piece of bone has been pulled away from the main bone (avulsion) at the inner bony prominence of the left elbow (medial epicondyle of the humerus). The fracture is displaced, meaning the bone fragments are not in their normal alignment, and the patient is in a subsequent phase of care where the fracture is not healing at the expected rate.
This code is appropriate for follow-up encounters when a patient with a previously diagnosed displaced avulsion fracture of the left humeral medial epicondyle presents with evidence of delayed union. This includes situations where imaging shows persistent fracture lines or callus formation is insufficient after the typical healing period.
