S52.502N Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Unspecified fracture of the lower end of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

An unspecified fracture of the lower end of the left radius involves a break in the distal portion of the radius bone near the wrist. This condition represents a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) that has not healed (nonunion). The term "unspecified" indicates that the exact fracture type or details are not documented in the medical record.

Causes

Typically results from trauma such as a fall onto an outstretched hand or direct impact to the wrist.

Risk Factors

• Increased likelihood with activities prone to falls, such as sports.
• Higher risk in older adults due to osteoporosis.
• Greater susceptibility in postmenopausal women.

Symptoms

• Persistent pain and swelling around the wrist.
• Difficulty or inability to move the wrist.
• Bruising and tenderness in the area of the fracture.
• Visible deformity in severe cases.
• Open wound (for type IIIA, IIIB, or IIIC open fractures).

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, primarily X-rays, to determine the exact location and severity of the fracture. Evaluation of the wound to classify the open fracture type. Additional imaging may be used to confirm nonunion.

Treatment Options

• Surgical intervention to address nonunion, such as bone grafting or internal fixation.
• Antibiotics to treat or prevent infection in open fractures.
• Immobilization using a cast or splint to support healing.
• Physical therapy to restore function and strength.

Prognosis and Follow-Up

Healing may be prolonged due to nonunion and open fracture complexity. Regular follow-up with imaging is necessary to monitor progress. Recovery depends on fracture severity, treatment effectiveness, and patient health.

Complications

• Infection at the fracture site.
• Nerve or blood vessel damage.
• Chronic pain or stiffness.
• Delayed or failed healing (nonunion).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).

When to Seek Professional Help

Seek immediate care for severe pain, swelling, deformity, or open wounds. Follow up with a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture (type IIIA, IIIB, or IIIC) with nonunion. Ensure the medical record specifies the fracture location (left radius) and the presence of nonunion. Code S52.502N is appropriate when the fracture type remains unspecified but the encounter and fracture characteristics are documented.
