ICD 10 CM S42.446S | Description & Clinical Information

ICD 10 S42.446S describes a specific type of fracture that occurs in the medial epicondyle of an unspecified humerus, which is a bony projection located on the inner side of the elbow that is responsible for muscle attachment, and this type of fracture is considered nondisplaced, meaning that there is no misalignment of the fractured fragments, and it is typically caused by high impact trauma resulting from incidents such as falling on an extended elbow, experiencing a forceful direct blow to the elbow, dislocating the elbow, or participating in sports activities, and it is important to note that the provider did not document whether the injury involves the right or left humerus at this encounter for a sequela, which is a condition that results from the fracture.

Clinical Information

The diagnosis describes by the ICD-10 CM S42.446S code is a specific fracture in the humerus bone of the upper arm. This condition occurs when the medial epicondyle, a bony prominence on the inner side of the humerus, suffers a nondisplaced fracture. Such a fracture is stable and remains in place, without disrupting the alignment of the bone parts.

People with this condition may experience severe pain and swelling in the upper arm, as well as bruising, tenderness, and pain while moving the arm or bearing weight. They may also suffer from limited range of motion as the injury affects the elbow joint.

To diagnose the condition, medical providers typically first evaluate the patient’s symptoms, medical history, and perform a physical examination. Additionally, imaging techniques such as X-rays, magnetic resonance imaging (MRI), and computed tomography (CT) may be employed to confirm the diagnosis, assess the extent of the injury, and identify any potential complications.

Stable and closed fractures of the medial epicondyle rarely require surgery, as they tend to heal on their own within a few weeks. In contrast, unstable fractures, which occur when the bone is displaced or fractures in more than one location, require fixation. In this case, doctors may need to use surgical implants or other devices to hold the bone in place while it heals.

Open fractures where the bone has pierced through the skin require surgery to clean and close the wound effectively. After the surgery, a person may be given antibiotics to prevent infection. Other treatment options for this condition may include the application of an ice pack, a splint or cast to restrict limb movement during the healing process, physical therapy to regain range of motion, as well as medications such as analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.

It is crucial to follow the treatment plan laid out by the healthcare provider, as well as any recommendations regarding rest, exercise, and rehabilitation. Adequate rest and care can help prevent complications associated with the condition, such as joint stiffness, bone deformities, and chronic pain. Overall, prompt and proper diagnosis and treatment of the S42.446S condition can help ensure effective healing, alleviate symptoms, and promote a full recovery.
