ICD-10-CMNondisplaced fracture (avulsion) of lateral epicondyle of right humerus, subsequent encounter for fracture with delayed healing
This code signifies a non-displaced avulsion fracture of the outer bony prominence of the right upper arm bone, specifically when the patient is receiving ongoing care for the fracture and it is healing slower than expected. An avulsion fracture occurs when a tendon or ligament pulls a small piece of bone away from the main bone.
Apply this code for follow-up encounters where a patient with a previously diagnosed non-displaced avulsion fracture of the right lateral epicondyle of the humerus is presenting for continued treatment due to delayed healing. This includes situations where the fracture site is still tender, swollen, or showing insufficient callus formation on imaging after the expected healing period.
