S52.521D Torus fracture of lower end of right radius, subsequent encounter for fracture with routine healing

Name of the Condition

• Torus fracture of lower end of right radius, subsequent encounter for fracture with routine healing

Summary

A torus fracture of the lower end of the right radius is an incomplete fracture involving the distal portion of the radius bone near the wrist. This type of fracture typically results in a buckling or compression of the bone cortex without complete displacement. The "subsequent encounter" designation indicates this is a follow-up visit for a fracture that is healing as expected, with no complications or delayed union.

Causes

Usually results from a fall onto an outstretched hand or direct impact to the wrist, where force is applied to the distal radius. The mechanism involves axial loading or bending forces that cause the bone to buckle rather than break completely.

Risk Factors

• Higher incidence in children and adolescents due to developing bone structure.
• Activities with a risk of falls, such as sports or play.
• Lack of protective gear during high-impact activities.

Symptoms

• Localized pain and swelling at the wrist.
• Tenderness to touch the affected area.
• Mild limitation in wrist movement.
• Possible visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, primarily X-rays, to confirm the fracture type and rule out other injuries. The torus fracture appears as a buckled or compressed area on imaging. The "subsequent encounter" status is determined by clinical documentation of routine healing progress.

Treatment Options

• Immobilization with a cast or splint to support healing and limit movement.
• Pain management as needed.
• Follow-up appointments to monitor healing progress.

Prognosis and Follow-Up

Most torus fractures heal well with appropriate immobilization, and routine healing is expected. Follow-up care ensures the fracture progresses without complications, and activities may be gradually resumed as healing allows.

Complications

• Rarely, malunion or delayed union if immobilization is inadequate.
• Nerve or tendon irritation from swelling or fracture fragments.
• Stiffness in the wrist or forearm if movement is restricted for too long.

Lifestyle & Prevention

• Use protective gear during sports or activities with fall risks.
• Maintain bone health through adequate nutrition and exercise.
• Practice safe falling techniques to reduce impact on the wrist.

When to Seek Professional Help

• Increased pain, swelling, or bruising.
• Numbness or tingling in the hand or fingers.
• Inability to move the wrist or forearm.
• Signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Document the fracture type (torus), location (lower end of right radius), and encounter status (subsequent) clearly in the medical record. Ensure the "routine healing" designation is supported by clinical notes indicating normal progress without complications. Code S52.521D is specific to the right radius and subsequent encounter; verify laterality and encounter details match the documentation.
