S52.222J Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Name of the Condition

• Displaced transverse fracture of shaft of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC 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 IIIA, IIIB, or IIIC) where healing is delayed. Open fractures involve a breach of the skin, and type III fractures are characterized by extensive soft tissue damage, contamination, or vascular injury. Delayed healing indicates the fracture has not progressed as expected during the normal recovery timeline.

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. Open fractures may result from severe trauma that disrupts both bone and soft tissue.

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, which may delay healing.
• Infection or contamination in open fractures, increasing healing complications.

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.
• Visible deformity if the fracture is displaced.
• Open wound at the fracture site (type IIIA, IIIB, or IIIC).
• Signs of delayed healing, such as lack of progress on imaging or prolonged pain.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate alignment and healing progress. Assessment of the open wound for type (IIIA, IIIB, or IIIC) and signs of infection or contamination. Evaluation of vascular status and soft tissue damage in open fractures.

Treatment Options

Stabilization of the fracture, often with surgical intervention (e.g., internal or external fixation) to realign and support the bone. Wound care for open fractures, including debridement and management of contamination. Antibiotics to prevent or treat infection. Monitoring for healing progress, with possible additional interventions if healing remains delayed. Physical therapy to restore function once the fracture is stable.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and response to treatment. Delayed healing may extend recovery time, requiring closer monitoring. Follow-up appointments to assess healing through imaging and clinical evaluation. Adjustments to treatment plans may be necessary if healing does not progress as expected.

Complications

Infection at the fracture site, particularly in open fractures. Nonunion or malunion of the fracture due to delayed healing. Nerve or vascular damage from the initial injury or surgical intervention. Chronic pain or reduced range of motion. Soft tissue scarring or contracture.

Lifestyle & Prevention

Avoid high-risk activities until the fracture is fully healed. Use protective gear during sports or activities with a fall risk. Maintain bone health through adequate nutrition (e.g., calcium, vitamin D) and exercise. Follow post-treatment guidelines to support healing and prevent re-injury.

When to Seek Professional Help

Persistent or worsening pain, swelling, or deformity. Signs of infection, such as redness, warmth, or pus at the wound site. Numbness, tingling, or changes in skin color (indicating vascular or nerve issues). Lack of healing progress over time, as indicated by imaging or clinical assessment.

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) of the left ulna shaft with delayed healing. Documentation must confirm the fracture type, laterality (left), and the presence of delayed healing. Ensure the encounter is classified as "subsequent" (not initial) and that the open fracture type is clearly specified. Delayed healing should be supported by clinical notes or imaging showing insufficient progress.
