S52.365H Nondisplaced segmental fracture of shaft of radius, left arm, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, left arm, subsequent encounter for open fracture type I or II with delayed healing
ICD-10 Code: S52.365H

Summary

A nondisplaced segmental fracture of the shaft of the radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the bone is separated into two or more fragments that remain in their original alignment. This injury typically results from significant trauma and may impair arm function depending on associated soft tissue damage. The "nondisplaced" nature means the bone fragments are not shifted out of position, which can influence treatment and recovery. The "subsequent encounter for open fracture type I or II with delayed healing" indicates this is a follow-up visit for a fracture that broke the skin with minimal contamination and is not healing as expected within the typical timeframe.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, high-impact blows to the forearm, or accidents involving twisting forces at the wrist or elbow. Motor vehicle collisions, sports injuries, or forceful impacts may also cause the bone to break into multiple segments without displacing them. Open fractures result when the broken bone pierces the skin, often from the same traumatic events. Delayed healing may stem from factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Participation in contact sports or activities with a high risk of falls
• Osteoporosis or weakened bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving repetitive stress or heavy lifting
• Smoking or poor nutrition, which can impair bone healing

Symptoms

• Persistent pain at the injury site beyond the expected healing period
• Swelling, bruising, or deformity of the forearm
• Inability to move the wrist or elbow fully
• Visible signs of the original open wound (if present)
• Possible numbness or tingling in the hand or fingers

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the fracture type and check for alignment. Additional tests, like CT scans or MRIs, may be ordered to evaluate soft tissue damage or assess healing progress. The healthcare provider will also review the patient’s medical history and previous treatment to determine the cause of delayed healing.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace to stabilize the bone. Physical therapy is often recommended to restore strength and mobility once healing progresses. In cases of severe delayed healing, surgical intervention, such as bone grafting or internal fixation, may be necessary. Antibiotics or wound care may be required if there are signs of infection from the original open fracture.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the patient’s overall health, and adherence to treatment. Most nondisplaced fractures heal with proper care, but delayed healing may extend recovery time. Regular follow-up appointments are essential to monitor progress and adjust treatment as needed. Full recovery can take several months, with gradual return to normal activities guided by the healthcare provider.

Complications

• Nonunion (failure of the bone to heal)
• Malunion (healing in an incorrect position)
• Infection, especially if the original fracture was open
• Chronic pain or stiffness in the forearm or wrist
• Nerve or blood vessel damage in severe cases

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a balanced diet rich in calcium and vitamin D to support bone health
• Use protective gear during sports or activities with fall risks
• Quit smoking, as it impairs bone healing
• Follow prescribed physical therapy to restore function

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe or worsening pain
• Increased swelling, redness, or drainage from the wound
• Numbness, tingling, or loss of circulation in the hand or fingers
• Inability to move the wrist or elbow

Tips for Medical Coders

Document the fracture type (open I or II), the affected side (left arm), and the reason for the subsequent encounter (delayed healing) to accurately assign S52.365H. Include details about the fracture’s alignment, any prior treatments, and the status of the original open wound. Ensure the medical record reflects the clinical rationale for delayed healing, such as imaging findings or patient factors, to support code specificity.
