S52.552K Other extraarticular fracture of lower end of left radius, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Other extraarticular fracture of lower end of left radius, subsequent encounter for closed fracture 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 "extraarticular" because it remains outside the joint capsule. It is a "subsequent encounter" indicating follow-up care for a previously treated fracture, and "closed" means the skin over the fracture site remains intact. The term "nonunion" signifies that the fracture has failed to heal properly after an expected period.

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, which can impede 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.
• Lack of healing progress over time, as indicated by imaging.

Diagnosis

Physical examination to assess pain, swelling, and functional impairment. Imaging tests, primarily X-rays, to confirm the fracture location, type, and severity, and to evaluate for nonunion. Additional imaging (e.g., CT scans) may be used for complex cases to evaluate bone alignment and healing status.

Treatment Options

• Immobilization with a cast or splint to support the fracture site.
• Pain management with prescribed medications.
• Surgical intervention may be necessary to realign and stabilize the bones using plates, screws, or bone grafts to promote healing.
• Physical therapy to restore strength and range of motion after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up care is essential to monitor healing progress and adjust treatment plans as needed. Regular imaging and clinical assessments help track recovery.

Complications

• Chronic pain and functional impairment.
• Increased risk of arthritis in the wrist joint over time.
• Potential need for additional surgeries if nonunion persists.
• Nerve or blood vessel damage in severe cases.

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 wrist injury risk.
• Follow post-fracture care instructions to support proper healing.

When to Seek Professional Help

Seek medical attention if persistent pain, swelling, or deformity occurs after a wrist injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment, as this may indicate nonunion or other complications.

Tips for Medical Coders

Document the fracture site (left radius), type (extraarticular, closed), and status (nonunion) clearly. Note the "subsequent encounter" context to reflect ongoing care for a previously treated fracture. Ensure clinical documentation supports the nonunion diagnosis to justify the code.
