S52.552M Other extraarticular fracture of lower end of left radius, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Other extraarticular fracture of lower end of left radius, subsequent encounter for open fracture type I or II with nonunion

Summary

This condition involves a fracture at the distal (lower) end of the left radius bone, near the wrist, that does not extend into the joint space. The fracture is classified as "open" (type I or II), meaning the skin is broken but contamination is minimal. The term "nonunion" indicates the fracture has failed to heal properly after an extended period. This is a subsequent encounter, meaning the patient is receiving follow-up care for the established nonunion.

Causes

Most commonly caused by trauma, such as falls onto an outstretched hand, direct blows to the wrist, or high-impact injuries during physical activities. Weakened bone structure due to conditions like osteoporosis may also contribute to fracture occurrence and subsequent nonunion.

Risk Factors

• Increased age, particularly in older adults with reduced bone density.
• Participation in contact sports or activities with a high risk of wrist injury.
• History of osteoporosis or prior fractures.
• Poor blood supply to the fracture site.
• Inadequate immobilization or premature weight-bearing during initial healing.

Symptoms

• Persistent pain, swelling, and tenderness localized to the wrist area.
• Bruising and limited range of motion in the affected wrist.
• Possible visible deformity or abnormal positioning of the wrist.
• Open wound at the fracture site (type I or II).
• No clinical or radiographic evidence of healing progress over time.

Diagnosis

Physical examination to assess pain, swelling, and functional impairment. Imaging tests, primarily X-rays, to confirm the fracture location, type, and the presence of nonunion (e.g., persistent fracture line, lack of callus formation). Additional imaging (e.g., CT scans) may be used to evaluate bone alignment and healing potential.

Treatment Options

• Surgical intervention to realign and stabilize the bones using plates, screws, or bone grafts.
• Immobilization with a cast or splint to support healing.
• Pain management with prescribed medications.
• Physical therapy to restore range of motion and strength.
• Monitoring for infection or other complications related to the open fracture.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, patient health, and response to treatment. Follow-up care is essential to monitor healing progress, adjust treatment plans, and address any complications. Regular imaging and clinical assessments are typically required.

Complications

• Persistent pain or functional impairment.
• Infection at the fracture site.
• Delayed or failed healing (nonunion).
• Arthritis or joint stiffness due to prolonged immobilization.
• Nerve or blood vessel damage.

Lifestyle & Prevention

• Avoid high-impact activities that risk wrist injury.
• Maintain bone health through adequate calcium and vitamin D intake.
• Use protective gear during sports or activities with fall risks.
• Follow post-treatment guidelines for immobilization and weight-bearing restrictions.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, deformity, or an open wound at the wrist. Contact your healthcare provider if symptoms worsen or do not improve with treatment, or if you notice signs of infection (e.g., redness, warmth, pus).

Tips for Medical Coders

Document the fracture type (open, type I or II), the presence of nonunion, and the subsequent encounter status. Ensure clinical notes specify the fracture location (lower end of left radius) and any contributing factors (e.g., trauma, osteoporosis) to support coding accuracy.
