S52.224D Nondisplaced transverse fracture of shaft of right ulna, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of right ulna, subsequent encounter for closed fracture with routine healing

Summary

A nondisplaced transverse fracture of the shaft of the right 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 fracture 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 confirm the fracture is closed, nondisplaced, and in the routine healing phase.

Treatment Options

Immobilization with a cast or splint to stabilize the fracture. Pain management with over-the-counter or prescription medications. Physical therapy to restore strength and mobility once healing progresses. Follow-up imaging to monitor 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 if the bone heals in an incorrect position. Infection (rare in 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. Maintain bone health through a balanced diet and regular exercise. Fall prevention strategies, such as removing tripping hazards at home.

When to Seek Professional Help

Severe pain that worsens or does not improve with treatment. New or worsening swelling, bruising, or deformity. Signs of infection, such as fever, redness, or drainage. Numbness, tingling, or weakness in the hand or fingers.

Tips for Medical Coders

Document the fracture as nondisplaced, transverse, and confined to the shaft of the right ulna. Confirm the encounter is subsequent and the fracture is closed with routine healing. Ensure clinical documentation supports the healing phase to justify the code.
