S52.502K Unspecified fracture of the lower end of left radius, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Unspecified fracture of the lower end of left radius, subsequent encounter for closed fracture 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 a closed fracture that has failed to heal (nonunion) after an initial treatment period. 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. Nonunion may occur due to inadequate immobilization, poor blood supply, infection, or excessive movement during healing.

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.
• Factors that impair healing, such as smoking or diabetes.

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.
• Possible clicking or grinding sensation with movement.

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 and confirm nonunion. Evaluation of healing progress compared to expected timelines.

Treatment Options

• Immobilization using a cast or splint to ensure proper bone healing for less severe fractures.
• Surgery in cases where bone fragments need realignment or stabilization using pins, plates, or screws.
• Bone grafting or electrical stimulation to promote healing in nonunion cases.

Prognosis and Follow-Up

Most fractures heal well with appropriate treatment, though recovery time varies based on fracture severity and patient healing capacity. Nonunion may require additional interventions, and follow-up imaging is often necessary to monitor progress.

Complications

• Chronic pain or stiffness.
• Arthritis in the wrist joint.
• Nerve or blood vessel damage.
• Infection (if surgery is performed).
• Reduced grip strength or function.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through proper nutrition and exercise.
• Follow post-treatment instructions carefully to support healing.

When to Seek Professional Help

• Persistent or worsening pain, swelling, or deformity.
• Inability to move the wrist or hand.
• Signs of infection, such as redness, warmth, or fever.
• New or worsening numbness or tingling.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the medical record specifies the fracture location (left radius) and confirms the absence of an open wound. Note any interventions or treatments provided during the encounter.
