S42.018S Nondisplaced fracture of sternal end of left clavicle, sequela

Name of the Condition

• Nondisplaced fracture of sternal end of left clavicle, sequela (ICD-10 Code: S42.018S)

Summary

This condition represents a healed or healing nondisplaced fracture of the sternal end of the left clavicle, where the bone fragments remain aligned and the injury is in a late stage of recovery. The term "sequela" indicates residual effects or complications following the initial fracture, such as persistent pain, limited mobility, or other long-term consequences. The clavicle, or collarbone, connects the arm to the body, and fractures at its sternal (chest) end may involve minor cracks or complete breaks without misalignment.

Causes

The sequela arises from a prior nondisplaced fracture of the sternal end of the left clavicle, typically caused by direct trauma to the shoulder or chest, such as a fall, motor vehicle accident, or forceful impact. The original injury did not displace the bone fragments, but residual effects may persist as the bone heals or due to incomplete recovery.

Risk Factors

Factors that may contribute to the development of sequela include inadequate initial treatment, delayed healing, or underlying conditions like osteoporosis that affect bone repair. High-impact activities or repeated stress on the clavicle during recovery could also increase the risk of persistent symptoms.

Symptoms

Symptoms may include localized pain at the sternal end of the left clavicle, reduced range of motion in the shoulder, or tenderness. Some individuals may experience swelling, bruising, or a palpable bump at the fracture site, even after the initial injury has healed.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility. Imaging, such as X-rays or CT scans, may be used to evaluate the healing process and identify any residual misalignment or complications. The history of a prior fracture is critical to confirming the sequela.

Treatment Options

Treatment focuses on managing residual symptoms and may include pain relief, physical therapy to restore function, or activity modification. In some cases, further evaluation or intervention may be needed if symptoms persist or worsen.

Prognosis and Follow-Up

Prognosis depends on the severity of the original injury and the effectiveness of recovery. Most individuals recover fully, but some may experience long-term discomfort or limited mobility. Follow-up care may involve periodic assessments to monitor healing and adjust treatment as needed.

Complications

Potential complications include chronic pain, reduced shoulder function, or nonunion (failure of the bone to heal properly). Rarely, nerve or blood vessel damage near the clavicle may occur, leading to additional symptoms.

Lifestyle & Prevention

Lifestyle modifications, such as avoiding high-impact activities, can help prevent re-injury. Strengthening exercises and proper posture may support recovery. For prevention of future fractures, maintaining bone health through diet and exercise is recommended.

When to Seek Professional Help

Seek medical attention if pain worsens, mobility decreases significantly, or new symptoms (e.g., numbness, swelling) develop. These may indicate a complication requiring further evaluation.

Tips for Medical Coders

This code is used for a sequela of a nondisplaced fracture of the sternal end of the left clavicle. Document the prior fracture and any residual effects clearly. Ensure the code aligns with the patient’s history and current clinical findings to reflect the sequela accurately.
