S52.263G Displaced segmental fracture of shaft of ulna, unspecified arm, subsequent encounter for closed fracture with delayed healing

Name of the Condition

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

Summary

A displaced 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 the bone is broken into two or more separate fragments, and these fragments are misaligned. This type of fracture involves the main body of the ulna and typically results from significant trauma, with the bone splitting into distinct segments that are not in their normal anatomical position. The fracture is closed (skin intact), and this is a subsequent encounter for treatment due to delayed healing.

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.
• Prolonged healing time or persistent symptoms indicating delayed union.

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, displacement, and healing status. Evaluation of healing progress to determine if delayed union is present.

Treatment Options

Immobilization with a cast or splint to stabilize the fracture. Pain management with medications or other therapies. Surgical intervention, if necessary, to realign and fix the bone fragments. Monitoring of healing progress through follow-up imaging and clinical assessments.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient factors, and adherence to treatment. Delayed healing may require extended immobilization or additional interventions. Regular follow-up appointments to monitor healing and adjust treatment as needed.

Complications

Delayed or nonunion of the fracture. Chronic pain or stiffness in the forearm. Nerve or blood vessel damage. Infection (if surgical intervention is required).

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 deformity. Inability to move the arm, wrist, or hand. Signs of infection, such as redness, warmth, or drainage. Delayed healing concerns based on clinical or imaging findings.

Tips for Medical Coders

Document the fracture type (displaced segmental), anatomical location (shaft of ulna, unspecified arm), encounter type (subsequent), and healing status (closed with delayed healing). Ensure clinical documentation supports the delayed healing classification and subsequent encounter timing. Code S52.263G is specific to closed fractures with delayed healing at a subsequent encounter.
