S52.225F Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

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

Summary

A nondisplaced transverse fracture of the shaft of the left ulna is a straight-line break across the long, central portion of the ulna bone (one of the two forearm bones) where the bone fragments remain in their normal anatomical alignment. The fracture runs horizontally through the bone shaft, and the lack of displacement means the bone pieces are not shifted out of position. This is a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC), indicating the fracture has breached the skin and is in a phase of routine healing after initial treatment.

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 common in nondisplaced cases).

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging studies, such as X-rays, to confirm the fracture type, location, and healing status. Evaluation of the open wound to determine the fracture type (IIIA, IIIB, or IIIC) and assess for infection or complications.

Treatment Options

Monitoring of routine healing with periodic imaging to ensure proper bone alignment and progression. Wound care for the open fracture site to prevent infection. Pain management through medications or other therapies. Physical therapy to restore strength and mobility once healing allows. Follow-up care to address any ongoing issues related to the fracture or wound.

Prognosis and Follow-Up

With proper treatment, nondisplaced fractures typically heal well, and routine healing is expected. Follow-up appointments are necessary to monitor progress, assess for complications, and adjust care as needed. Full recovery may take several weeks to months, depending on the severity of the injury and individual healing factors.

Complications

Infection at the open fracture site. Delayed healing or nonunion of the bone. Nerve or vascular damage from the initial injury or during healing. Limited range of motion or stiffness in the forearm or wrist.

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. Engage in regular weight-bearing exercise to strengthen bones. Use proper safety measures, such as wearing seatbelts or protective equipment, to reduce the risk of falls or accidents.

When to Seek Professional Help

Increased pain, swelling, or redness around the fracture site. Signs of infection, such as fever, pus, or foul odor from the wound. Numbness, tingling, or loss of circulation in the hand or fingers. Difficulty moving the arm or wrist despite treatment.

Tips for Medical Coders

This code is used for a subsequent encounter of a nondisplaced transverse fracture of the left ulna shaft with an open fracture type IIIA, IIIB, or IIIC, where routine healing is occurring. Documentation should specify the fracture type, the encounter type (subsequent), and confirmation of routine healing. Ensure the open fracture classification (IIIA, IIIB, or IIIC) is clearly documented to support the code assignment.
