S52.266G Nondisplaced segmental fracture of shaft of ulna, unspecified arm, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of ulna, unspecified arm, subsequent encounter for closed fracture with delayed healing

Summary

A nondisplaced segmental fracture of the shaft of the ulna, unspecified arm, is a break in the long, straight portion of the ulna bone (one of the two forearm bones) where there are two separate fracture lines creating a free-floating bone segment, and the bone fragments remain in their normal anatomical alignment. This type of fracture involves the main body of the ulna and typically results from trauma, with the bone splitting into distinct segments without displacement. The term "subsequent encounter for closed fracture with delayed healing" indicates this is a follow-up visit for a fracture where the skin is intact, and healing is progressing more slowly than 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 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.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, to confirm the fracture type and assess healing progress. Evaluation of healing status to determine if delayed healing is present.

Treatment Options

Immobilization with a cast or splint to stabilize the fracture. Pain management with medications or other therapies. Follow-up imaging to monitor healing. Possible surgical intervention if healing does not progress as expected.

Prognosis and Follow-Up

Most nondisplaced fractures heal with proper immobilization, but delayed healing may require extended follow-up. Regular monitoring with imaging and clinical assessments is necessary to track progress. Recovery time varies depending on the individual and the extent of the injury.

Complications

Delayed or nonunion of the fracture. Chronic pain or stiffness in the forearm. Nerve or blood vessel damage in severe cases. Infection (rare, but possible if open fracture occurs).

Lifestyle & Prevention

Avoid high-risk activities that may lead to falls or trauma. Maintain bone health through proper nutrition and exercise. Use protective gear during sports or activities with a risk of injury. Follow post-injury care instructions to support healing.

When to Seek Professional Help

Persistent or worsening pain, swelling, or bruising. Difficulty moving the arm or hand. Signs of infection, such as redness, warmth, or drainage. Numbness or tingling in the hand or fingers.

Tips for Medical Coders

Document the fracture type (nondisplaced segmental), location (shaft of ulna, unspecified arm), and encounter details (subsequent, closed, delayed healing) to ensure accurate coding. Include clinical notes supporting the diagnosis of delayed healing, such as imaging findings or provider observations, to justify the code selection.
