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

Name of the Condition

• Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type I or II with delayed 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 healing is delayed, indicating the fracture has not progressed as expected during treatment.

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.
• Poor blood supply to the fracture site.
• Inadequate immobilization or non-compliance with treatment.

Symptoms

• Persistent 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).
• Delayed healing signs, such as lack of radiographic progress over time.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to evaluate fracture alignment and healing progress. Assessment of the open wound (type I or II) and documentation of delayed healing. Review of prior treatment and clinical timeline to confirm subsequent encounter.

Treatment Options

• Continued immobilization with a cast or brace to support healing.
• Wound care for the open fracture site to prevent infection.
• Pain management with medications as needed.
• Possible surgical intervention if healing does not improve.
• Physical therapy to restore function once healing advances.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and adherence to treatment. Delayed healing may extend recovery time. Regular follow-up visits are necessary to monitor progress, adjust treatment, and address complications. Healing may require additional imaging to confirm union.

Complications

• Infection at the open fracture site.
• Nonunion or malunion of the fracture.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Limited range of motion in the forearm or wrist.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Ensure proper nutrition to support bone health.
• Follow immobilization and weight-bearing restrictions.
• Use protective gear during sports or activities.
• Maintain regular follow-up appointments.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., fever, wound drainage) develop. Contact a healthcare provider if there is no improvement in healing or if mobility does not improve over time.

Tips for Medical Coders

Document the fracture type (open I or II), location (left ulna shaft), displacement, and confirmation of delayed healing. Include details of the subsequent encounter, such as prior treatment and clinical assessment of healing progress. Ensure alignment with the open fracture classification and delayed healing criteria for accurate coding.
