S52.264E Nondisplaced segmental fracture of shaft of ulna, right arm, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of ulna, right arm, subsequent encounter for open fracture type I or II with routine healing

Summary

A nondisplaced segmental fracture of the shaft of the ulna, right arm, is a break in the long, straight portion of the ulna bone (one of the two forearm bones) where the bone is broken into two or more separate fragments, but these fragments remain in their normal anatomical alignment. This type of fracture involves the main body of the ulna and is classified as an open fracture type I or II, meaning there is a break in the skin with minimal contamination or a larger wound with moderate contamination, respectively. The fracture is described as "subsequent encounter," indicating follow-up care after the initial treatment, and "with routine healing" confirms the fracture is progressing normally without complications.

Causes

Direct trauma to the forearm, such as from a fall, blow, or accident. High-impact injuries, including sports-related incidents or motor vehicle collisions. Indirect forces transmitted through the wrist or elbow, potentially causing a break in the ulna shaft.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Previous fractures or bone abnormalities that may predispose to injury.
• Advanced age, which can reduce bone strength.

Symptoms

• Pain and tenderness localized to the forearm.
• Swelling and bruising around the injured area.
• Difficulty moving the arm, wrist, or hand due to pain or instability.
• Possible visible deformity if the fracture is displaced (though less likely with nondisplaced fractures).
• Open wound (for type I or II) with or without minimal contamination.

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the fracture type, location, and alignment. Additional tests, like CT scans, may be ordered if more detailed visualization is needed. The open fracture classification (type I or II) is determined by the size and contamination of the skin wound.

Treatment Options

Treatment focuses on immobilization with a cast or splint to allow healing. For open fractures, wound care is essential to prevent infection. Pain management and physical therapy may be recommended to restore function. Surgical intervention is rarely needed for nondisplaced fractures but may be considered if alignment is compromised.

Prognosis and Follow-Up

With routine healing, the prognosis is generally good, and most fractures heal within 6–8 weeks. Follow-up appointments monitor healing progress through imaging and physical assessments. Full recovery of strength and mobility may take several months, depending on the individual's response to treatment.

Complications

• Infection, particularly with open fractures.
• Delayed healing or nonunion if the fracture does not heal properly.
• Stiffness or reduced range of motion in the forearm or wrist.
• Nerve or blood vessel damage, though rare with nondisplaced fractures.

Lifestyle & Prevention

• Avoid high-risk activities or use protective gear during sports.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Use proper techniques to prevent falls, such as wearing appropriate footwear.
• Seek prompt treatment for any forearm injuries to reduce complication risks.

When to Seek Professional Help

• Severe or worsening pain that is not relieved by rest or medication.
• Increased swelling, redness, or drainage from the wound.
• Signs of infection, such as fever or pus.
• Numbness, tingling, or loss of circulation in the hand or fingers.
• Inability to move the arm or wrist after initial treatment.

Tips for Medical Coders

This code (S52.264E) is used for a subsequent encounter of a nondisplaced segmental fracture of the ulna shaft, right arm, with an open fracture type I or II and routine healing. Documentation should specify the fracture type, laterality, encounter type (subsequent), and healing status. Ensure the open fracture classification (type I or II) and routine healing are clearly documented to support accurate coding.
