S52.225D Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for closed fracture 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 a closed fracture with routine healing, indicating the injury is in the healing phase and the skin remains intact.

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 tests, such as X-rays, to confirm the fracture and evaluate alignment. Additional imaging (e.g., CT scans) may be used for complex cases. Documentation should reflect the fracture type, location, and healing status.

Treatment Options

Immobilization with a cast or splint to stabilize the bone during healing. Pain management with over-the-counter or prescription medications. Physical therapy to restore strength and mobility once healing progresses. Follow-up imaging to monitor fracture healing.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and care. Follow-up appointments are typically scheduled to assess healing progress and adjust treatment as needed. Full recovery may take several weeks to months, depending on the individual and fracture severity.

Complications

Delayed healing or nonunion if the fracture does not heal properly. Malunion, where the bone heals in an abnormal position. Infection (rare, especially with closed fractures). Nerve or blood vessel damage near the fracture site.

Lifestyle & Prevention

Avoid high-risk activities until fully healed. Use protective gear during sports or activities with fall risks. Maintain bone health through a balanced diet rich in calcium and vitamin D. Engage in regular weight-bearing exercise to support bone density.

When to Seek Professional Help

Persistent or worsening pain, swelling, or bruising. Signs of infection, such as fever, redness, or drainage. Numbness, tingling, or weakness in the hand or fingers. Difficulty moving the arm or wrist after immobilization is removed.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), location (shaft of left ulna), encounter type (subsequent), and healing status (routine healing) to support accurate coding. Ensure clinical notes specify the fracture is closed and healing without complications. Verify that the encounter aligns with the "subsequent" phase of care for proper code assignment.
