S52.365F Nondisplaced segmental fracture of shaft of radius, left arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, left arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
ICD-10 Code: S52.365F

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 IIIA, IIIB, or IIIC" indicates this is a follow-up visit for a fracture where the skin was broken with severe contamination or tissue loss, and "with routine healing" specifies the fracture is progressing normally without complications.

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, and the severity (types IIIA, IIIB, or IIIC) reflects the extent of soft tissue damage and contamination.

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

Symptoms

• Sudden, severe pain at the injury site
• Swelling, bruising, or deformity of the forearm
• Inability to move the wrist or elbow without pain
• Visible wound or open skin at the fracture site (for open fractures)
• Numbness or tingling in the hand or fingers (if nerves are affected)

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays to confirm the fracture type and alignment. For open fractures, additional evaluation of the wound and surrounding tissue may be necessary to determine the severity of contamination or tissue loss. Clinical documentation should specify the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing during the subsequent encounter.

Treatment Options

Treatment focuses on stabilizing the fracture and promoting healing. This may include immobilization with a cast or splint, pain management, and monitoring for infection in open fractures. Surgical intervention is sometimes required to clean the wound or repair damaged tissue, especially for severe open fractures. Physical therapy may be recommended to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

With proper treatment and routine healing, most nondisplaced segmental fractures of the radius heal well, though recovery time varies. Follow-up visits are essential to monitor healing and adjust treatment as needed. Open fractures require close observation for signs of infection or delayed healing, and rehabilitation may be necessary to regain full function.

Complications

Potential complications include infection (especially with open fractures), delayed union or nonunion of the bone, nerve or blood vessel damage, and long-term stiffness or weakness in the arm. Severe open fractures (types IIIB or IIIC) carry a higher risk of complications due to extensive tissue damage.

Lifestyle & Prevention

To reduce fracture risk, maintain bone health through a diet rich in calcium and vitamin D, engage in weight-bearing exercise, and avoid activities with a high fall risk. For those with osteoporosis, consult a healthcare provider about bone-strengthening medications. Use protective gear during sports or high-risk activities, and practice proper techniques to avoid traumatic injuries.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury, or if an open wound is present. Contact your healthcare provider if you notice increasing pain, redness, or drainage from the fracture site, as these may indicate infection or delayed healing.

Tips for Medical Coders

When coding S52.365F, ensure documentation specifies the fracture as nondisplaced, segmental, and of the left radius shaft. Confirm the encounter is subsequent (not initial) and that the open fracture is classified as type IIIA, IIIB, or IIIC. Document "routine healing" to justify the code, as this indicates the fracture is progressing without complications. Verify laterality (left arm) and fracture type details to avoid miscoding.
