S42.036 Nondisplaced fracture of lateral end of unspecified clavicle

Name of the Condition

• Nondisplaced fracture of lateral end of unspecified clavicle

Summary

A nondisplaced fracture of the lateral end of the unspecified 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, which connects to the shoulder, and does not result in misalignment of the bone fragments.

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 range of motion and strength once healing progresses.
• Surgical intervention is rarely required for nondisplaced fractures but may be considered if there are complications.

Prognosis and Follow-Up

Most nondisplaced clavicle fractures heal well with conservative treatment. Recovery typically takes 6–8 weeks, during which follow-up appointments monitor healing progress. Full return to normal activities is usually possible, though high-impact activities may be restricted until cleared by a healthcare provider.

Complications

• Delayed healing or nonunion, particularly in older adults or those with poor bone health.
• Nerve or blood vessel injury near the fracture site.
• Persistent pain or stiffness in the shoulder.
• Malunion, though less common with nondisplaced fractures.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Practice fall prevention strategies, especially for older adults.
• Avoid falls by using assistive devices if needed and keeping living spaces clear of hazards.

When to Seek Professional Help

Seek medical attention if you experience severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., redness, fever). Immediate care is also recommended after a significant injury to the shoulder or clavicle.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the lateral end of the clavicle. Include details about the injury mechanism, imaging results, and treatment plan to support coding accuracy. Ensure the "unspecified" designation is appropriate if the side is not documented.
