S42.035G Nondisplaced fracture of lateral end of left clavicle, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of lateral end of left clavicle, subsequent encounter for fracture with delayed healing

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 in their normal alignment. This type of fracture involves the lateral (outer) segment of the clavicle, which connects to the shoulder joint. The "subsequent encounter" modifier indicates this is a follow-up visit for an established fracture, and "delayed healing" specifies that the fracture is not progressing as expected during the normal healing timeline.

Causes

Clavicle fractures often occur due to 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. Delayed healing can result from factors like poor blood supply, inadequate immobilization, or underlying health conditions affecting bone repair.

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.
• Smoking or poor nutrition, which can impair healing.

Symptoms

• Persistent 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 (may be subtle in nondisplaced cases).
• Prolonged healing time compared to typical fracture recovery.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and deformity. Imaging, typically X-rays, confirms the fracture and its location. In cases of delayed healing, additional imaging (e.g., CT or MRI) may be used to evaluate bone union and rule out complications. Clinical documentation must specify the fracture's status and the reason for delayed healing to support the code.

Treatment Options

Treatment focuses on promoting healing and may include:

• Continued immobilization with a sling or brace.
• Pain management with medications.
• Physical therapy to restore range of motion and strength.
• Monitoring for signs of improved healing or complications.
• In rare cases, surgical intervention if healing does not progress.

Prognosis and Follow-Up

Most nondisplaced clavicle fractures heal with conservative management, but delayed healing may extend recovery time. Regular follow-up appointments are necessary to assess progress through imaging and clinical evaluation. Full recovery can take several months, depending on the individual's health and adherence to treatment.

Complications

• Nonunion (failure of the bone to heal).
• Malunion (healing in an abnormal position).
• Chronic pain or stiffness.
• Nerve or blood vessel damage near the fracture site.
• Reduced shoulder function.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health with a balanced diet rich in calcium and vitamin D.
• Avoid smoking, which impairs bone healing.
• Practice fall prevention strategies, especially for older adults.
• Follow post-injury care instructions to support proper healing.

When to Seek Professional Help

Seek medical attention if you experience:

• Increasing pain, swelling, or deformity.
• Numbness, tingling, or weakness in the arm or hand.
• Signs of infection (e.g., redness, warmth, fever).
• No improvement in symptoms after several weeks of treatment.

Tips for Medical Coders

This code (S42.035G) requires documentation of a nondisplaced fracture of the lateral end of the left clavicle, a subsequent encounter, and delayed healing. Ensure the medical record specifies the fracture's location, laterality, and the reason for delayed healing (e.g., lack of radiographic evidence of union). The "subsequent encounter" modifier applies to follow-up care, and "delayed healing" must be clinically supported to justify the code.
