ICD-10-CMNondisplaced fracture (avulsion) of medial epicondyle of unspecified humerus, subsequent encounter for fracture with malunion
This code signifies a follow-up encounter for a patient who previously sustained an avulsion fracture of the medial epicondyle of an unspecified humerus. At this subsequent visit, the fracture is noted to have healed in an unsatisfactory position, resulting in malunion. The fracture itself was initially nondisplaced.
Apply this code when a patient presents for ongoing management or evaluation of a previously treated medial epicondyle avulsion fracture that has healed incorrectly. This typically involves cases where imaging confirms a malunion and the patient is past the initial healing phase. It is used for encounters addressing the complications of the malunion, not the initial injury.
