S52.231D Displaced oblique fracture of shaft of right ulna, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Displaced Oblique Fracture of Shaft of Right Ulna, Subsequent Encounter for Closed Fracture with Routine Healing
• ICD Code: S52.231D
• Also referred to as: Right Ulna Shaft Fracture

Summary

A displaced oblique fracture of the shaft of the right ulna is a break in the long, straight portion of the right ulna bone, where the fracture line is angled and the bone fragments are not aligned. This code applies to a follow-up encounter for a closed fracture (skin intact) with healing progressing as expected.

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 along the forearm.
• Swelling and bruising around the injured area.
• Limited range of motion or difficulty moving the wrist or hand.
• Visible deformity or bump at the fracture site.

Diagnosis

Physical examination to assess swelling, bruising, and range of motion. Imaging tests, such as X-rays, to visualize the fracture and confirm alignment. Follow-up imaging may be used to monitor healing progress.

Treatment Options

• Immobilization: Casting or splinting to maintain bone position during healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore strength and mobility once healing allows.
• Surgery: May be considered if alignment issues persist or healing is compromised.

Prognosis and Follow-Up

Most fractures heal with proper immobilization and care, with full recovery expected in several weeks to months. Follow-up visits are important to monitor healing and adjust treatment as needed. Routine healing typically results in good functional outcomes.

Complications

• Delayed union or nonunion of the fracture.
• Malunion (improper healing leading to misalignment).
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or stiffness in the forearm.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid falls by improving home safety (e.g., removing tripping hazards).
• Follow post-injury guidelines to support proper healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, coldness) develop. Contact a provider if the cast or splint becomes loose or damaged, or if healing does not progress as expected.

Tips for Medical Coders

Document the fracture type (displaced oblique), location (shaft of right ulna), encounter type (subsequent), and healing status (routine) to support accurate coding. Include details on imaging, treatment, and follow-up to confirm the fracture is closed and healing as expected.
