S42.017A Nondisplaced fracture of sternal end of right clavicle, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of sternal end of right clavicle, initial encounter for closed fracture (ICD-10 Code: S42.017A)

Summary

This condition involves a break at the sternal (chest) end of the right clavicle where the bone fragments remain in their normal alignment. The clavicle, or collarbone, connects the arm to the body and is a common site for fractures due to its exposed position. A nondisplaced fracture means the bone has cracked but has not shifted out of place, and the encounter is for an initial, closed (skin intact) injury.

Causes

Fractures of the clavicle’s sternal end typically result from direct trauma to the shoulder or chest, such as a fall onto the shoulder, a blow to the chest, or a motor vehicle accident. The nondisplaced nature indicates the force was sufficient to break the bone but not to displace the fragments.

Risk Factors

Factors increasing the risk include participation in contact sports, osteoporosis or reduced bone density, and activities with a high risk of falls or collisions. Older adults may be more susceptible due to age-related bone changes.

Symptoms

Symptoms often include localized pain at the sternal end of the right clavicle, swelling, bruising, and tenderness. A visible or palpable deformity may be present, along with difficulty moving the shoulder or arm due to pain.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and deformity. X-ray imaging confirms the fracture and verifies it is nondisplaced. Additional imaging like CT or MRI may be used for complex cases.

Treatment Options

Treatment typically includes immobilization with a sling to support the arm, pain management, and activity modification. Most nondisplaced fractures heal with conservative care, though follow-up imaging may be used to monitor healing.

Prognosis and Follow-Up

Prognosis is generally favorable, with most fractures healing within 6–8 weeks. Follow-up appointments monitor pain, mobility, and healing progress. Physical therapy may be recommended to restore strength and range of motion once the fracture is stable.

Complications

Complications are rare but may include nonunion (failure to heal), malunion (healing in an abnormal position), or nerve irritation. Infection is unlikely with a closed fracture but may occur if the skin is compromised.

Lifestyle & Prevention

Preventive measures include wearing protective gear during contact sports, maintaining bone health through diet and exercise, and avoiding high-risk activities. Strengthening shoulder and upper body muscles may reduce injury risk.

When to Seek Professional Help

Seek care if pain is severe, swelling worsens, or movement is severely limited. Immediate attention is needed if numbness, tingling, or changes in skin color occur, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Document the fracture location (sternal end of right clavicle), displacement status (nondisplaced), encounter type (initial), and fracture type (closed) to support code S42.017A. Include details on imaging, treatment, and follow-up to ensure accurate coding and billing.
