S52.222E Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

• Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type I or II 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 in the forearm, with the bone fragments shifted out of alignment. This code applies to a subsequent encounter for an open fracture (type I or II) where the fracture is healing routinely, indicating the skin was breached but the wound is now healing without complications.

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.
• Open wound at the fracture site (type I or II open fracture) that is now healing.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate healing progress. Assessment of the wound site to determine if healing is routine.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture during healing.
• Pain management with medications as needed.
• Wound care for the open fracture site to prevent infection.
• Physical therapy to restore strength and mobility once healing allows.
• Surgical intervention if alignment or stability is compromised.

Prognosis and Follow-Up

Most fractures with routine healing respond well to treatment, with full recovery expected over several weeks to months. Follow-up visits monitor healing progress, adjust immobilization, and guide rehabilitation. Routine healing indicates no significant complications, but adherence to treatment plans is essential.

Complications

• Infection at the open fracture site.
• Delayed union or nonunion of the fracture.
• Nerve or blood vessel damage.
• Stiffness or reduced range of motion in the forearm or wrist.
• Malunion if the fracture does not heal in proper alignment.

Lifestyle & Prevention

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

When to Seek Professional Help

• Increased pain, swelling, or redness at the fracture site.
• Signs of infection (e.g., pus, fever).
• Numbness, tingling, or coldness in the hand or fingers.
• Difficulty moving the arm or wrist despite treatment.
• Wound reopening or delayed healing.

Tips for Medical Coders

This code is for a subsequent encounter of a displaced transverse fracture of the left ulna shaft with an open fracture type I or II that is healing routinely. Document the fracture type, laterality, and healing status to support coding. Ensure the encounter is subsequent (not initial) and that the fracture is classified as open type I or II with routine healing.
