S42.035A Nondisplaced fracture of lateral end of left clavicle, initial encounter for closed fracture

Name of the Condition

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

Summary

A nondisplaced fracture of the lateral end of the left clavicle is a break in the outer portion of the left collarbone where the bone fragments remain aligned. This type of fracture involves the lateral (outer) segment of the clavicle, which connects to the shoulder, and is classified as closed (no skin penetration) during the initial encounter.

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.

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 strength and mobility once healing progresses.

Prognosis and Follow-Up

Most nondisplaced clavicle fractures heal well with conservative treatment. Follow-up appointments monitor healing progress, and activity restrictions are gradually lifted as the bone strengthens. Full recovery typically occurs within 6–12 weeks, depending on the individual.

Complications

• Delayed healing or nonunion (failure to heal).
• Malunion (healing in an abnormal position).
• Nerve or blood vessel injury near the fracture site.
• Chronic pain or shoulder stiffness.

Lifestyle & Prevention

• Use protective gear during contact sports.
• Maintain bone health through adequate calcium and vitamin D intake.
• Practice fall prevention strategies, especially for older adults.
• Avoid high-impact activities that increase fracture risk.

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, specify the left lateral end of the clavicle, and confirm the encounter is initial and the fracture is closed. Include details on imaging results, treatment provided, and any follow-up plans to support accurate coding.
