S52.382K Bent bone of left radius, subsequent encounter for closed fracture with nonunion

Name of the Condition

Bent bone of left radius, subsequent encounter for closed fracture with nonunion
ICD-10 Code: S52.382K

Summary

This condition describes a bent left radius bone during a subsequent encounter, where a closed fracture has failed to heal (nonunion). The radius, the long outer bone of the forearm, remains deformed due to incomplete healing of a prior fracture that did not break the skin. Nonunion indicates the bone has not fused properly, often requiring additional intervention. The "subsequent encounter" designation applies to follow-up care after the initial injury, and "closed" means the fracture site remains intact without open wounds.

Causes

This condition typically results from a prior closed fracture of the left radius that did not heal correctly. Contributing factors may include inadequate immobilization, poor blood supply to the bone, infection, or excessive movement during healing. Trauma from falls, direct blows, or twisting injuries can initiate the initial fracture, with nonunion developing if healing is disrupted.

Risk Factors

• Poor blood supply to the fracture site
• Inadequate immobilization or premature weight-bearing
• Smoking or other factors that impair healing
• Nutritional deficiencies (e.g., vitamin D, calcium)
• Underlying conditions like diabetes or osteoporosis

Symptoms

• Persistent pain at the fracture site, often dull or aching
• Visible deformity or angulation of the forearm
• Reduced range of motion in the wrist or elbow
• Possible instability or weakness in the arm
• No open wounds or signs of infection

Diagnosis

Diagnosis involves a physical exam to assess deformity, pain, and function, followed by imaging. X-rays or CT scans confirm the nonunion and evaluate bone alignment. Additional tests may check for infection or assess blood flow. Clinical history of prior fracture and lack of healing over time support the diagnosis.

Treatment Options

Treatment focuses on promoting bone healing or stabilizing the fracture. Options may include surgical fixation (e.g., plates, screws), bone grafting to stimulate healing, or external fixation devices. Non-surgical approaches like bracing or physical therapy may be used if appropriate. Pain management and activity modification are also part of care.

Prognosis and Follow-Up

Prognosis depends on the severity of nonunion and treatment response. Surgical intervention often improves outcomes, but recovery may take months. Regular follow-up with imaging monitors healing. Long-term function depends on successful union and rehabilitation.

Complications

• Chronic pain or disability
• Persistent deformity affecting arm function
• Increased risk of future fractures
• Nerve or blood vessel damage from unstable bone
• Infection (if surgery is performed)

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a provider
• Follow immobilization or weight-bearing restrictions strictly
• Maintain a balanced diet rich in calcium and vitamin D
• Quit smoking to support healing
• Use protective gear during sports or risky activities

When to Seek Professional Help

Seek care if pain worsens, deformity increases, or new symptoms (e.g., numbness, swelling) develop. Prompt evaluation is needed if the arm feels unstable or function declines, as these may indicate complications requiring intervention.

Tips for Medical Coders

Code S52.382K is used for a subsequent encounter of a closed left radius fracture with nonunion. Document the encounter type (subsequent), fracture status (closed), and nonunion to justify the code. Ensure clinical notes specify the bone (left radius), fracture type, and healing status to support accurate coding.
