S52.222D Displaced transverse fracture of shaft of left ulna, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Displaced transverse fracture of shaft of left ulna, subsequent encounter for closed fracture with routine healing

Summary

A displaced transverse fracture of the shaft of the left ulna is a horizontal break across the long, central portion of the ulna bone (one of the two forearm bones) where the bone fragments are shifted out of alignment. This code applies to 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.

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.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Pain management with medications or other therapies.
• Physical therapy to restore strength and mobility once healing progresses.
• Surgical intervention if the fracture requires realignment or stabilization.

Prognosis and Follow-Up

Most fractures heal with proper treatment, though recovery time varies. Follow-up appointments monitor healing progress and adjust care as needed. Routine healing indicates the fracture is progressing without complications.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in a misaligned position.
• Infection (rare, but possible with open fractures).
• Nerve or blood vessel damage near the fracture site.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Follow post-injury guidelines to support healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. Contact a provider if the cast or splint becomes loose or uncomfortable.

Tips for Medical Coders

Document the fracture type (displaced transverse), location (shaft of left ulna), encounter type (subsequent), and healing status (routine healing). Ensure clinical notes support the closed fracture and healing phase to justify the code.
