S52.222F Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Summary

A displaced transverse fracture of the shaft of the left ulna is a horizontal break across the long, central portion of the ulna bone in the forearm, with the bone fragments shifted out of alignment. This code applies to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) where the skin is breached, and the fracture is healing as expected 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.
• Open wound at the fracture site (type IIIA, IIIB, or IIIC open fracture).

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate alignment. Assessment of the open wound to determine fracture type (IIIA, IIIB, or IIIC) and healing status.

Treatment Options

Stabilization of the fracture, such as with a cast or external fixator. Wound care for the open fracture site. Pain management and physical therapy to restore function. Monitoring for signs of infection or delayed healing.

Prognosis and Follow-Up

With routine healing, most fractures heal within several months. Follow-up visits to assess alignment, wound healing, and functional recovery. Physical therapy may be needed to regain strength and mobility.

Complications

Infection at the open fracture site. Delayed union or nonunion of the fracture. Nerve or vascular damage. Reduced range of motion or chronic pain.

Lifestyle & Prevention

Avoid high-risk activities that may lead to falls or trauma. Use protective gear during sports or work. Maintain bone health through diet and exercise to reduce fracture risk.

When to Seek Professional Help

Increased pain, swelling, or redness at the fracture site. Signs of infection, such as fever or pus. Numbness, tingling, or coldness in the hand or fingers. Difficulty moving the arm or wrist.

Tips for Medical Coders

Use this code for a subsequent encounter of a displaced transverse fracture of the left ulna shaft with an open fracture type IIIA, IIIB, or IIIC that is healing routinely. Document the fracture type, encounter type, and healing status to support code assignment.
