S42.036A Nondisplaced fracture of lateral end of unspecified clavicle, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of lateral end of unspecified clavicle, initial encounter for closed fracture

Summary

A nondisplaced fracture of the lateral end of the clavicle is a break in the outer portion of the collarbone where the bone fragments remain aligned. This type of fracture involves the lateral (outer) segment of the clavicle and is classified as closed, meaning the skin is intact. The initial encounter indicates this is the first time the fracture is being treated.

Causes

Clavicle fractures typically result from direct trauma to the shoulder, such as a fall onto the shoulder, a blow to the area, or a forceful impact during sports or accidents. Falls onto an outstretched hand may also transmit stress to the clavicle, leading to fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or weakened bone density.
• Older age, due to increased fall risk and bone fragility.
• Previous shoulder or clavicle injuries.

Symptoms

• Pain, swelling, or tenderness over the lateral clavicle.
• Bruising or discoloration around the shoulder.
• Difficulty moving the arm or shoulder.
• A visible bump or deformity at the fracture site (less common with nondisplaced fractures).

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and deformity. Imaging, typically X-rays, confirms the fracture and its location. In complex cases, CT or MRI may be used to evaluate alignment or associated soft tissue damage.

Treatment Options

• Immobilization with a sling or brace to stabilize the fracture and promote healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore range of motion and strength once healing progresses.
• Follow-up imaging to monitor bone alignment and healing.

Prognosis and Follow-Up

Most nondisplaced clavicle fractures heal well with conservative treatment. Healing typically occurs within 6–12 weeks, depending on the patient’s age and overall health. Follow-up appointments are important to assess healing and adjust treatment as needed.

Complications

• Delayed healing or nonunion (rare).
• Malunion (misalignment of the bone during healing).
• Nerve or blood vessel injury (uncommon).
• Chronic pain or stiffness in the shoulder.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid falls by using assistive devices if needed, especially in older adults.
• Strengthen shoulder and upper body muscles to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, redness, drainage) at the fracture site.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the lateral end of the clavicle. Note the initial encounter and closed nature of the fracture. Ensure the medical record supports the absence of displacement and the integrity of the skin.
