S52.365D Nondisplaced segmental fracture of shaft of radius, left arm, subsequent encounter for closed fracture with routine healing

Name of the Condition

Nondisplaced segmental fracture of shaft of radius, left arm, subsequent encounter for closed fracture with routine healing
ICD-10 Code: S52.365D

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 closed fracture with routine healing" indicates this is a follow-up visit for a fracture where the skin is intact and healing 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. The "closed fracture" designation means the skin remains intact, and "routine healing" suggests no significant complications during recovery.

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

• Mild to moderate pain at the injury site, often decreasing over time
• Residual swelling or bruising as healing progresses
• Possible stiffness or limited range of motion in the forearm or wrist
• No visible deformity, as the fracture remains nondisplaced
• Normal sensation and circulation in the hand and fingers

Diagnosis

Diagnosis typically 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, location, and healing status. The "subsequent encounter" context implies prior documentation of the initial fracture and treatment, with follow-up imaging to verify routine healing. Clinical notes should reflect the absence of complications and evidence of progressive bone union.

Treatment Options

Treatment focuses on maintaining alignment and promoting healing. This may include immobilization with a cast or splint, pain management, and gradual rehabilitation exercises to restore function. Follow-up care ensures the fracture heals without displacement or other issues. No surgical intervention is typically needed for nondisplaced fractures with routine healing.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures with routine healing, as the bone fragments remain aligned and heal without complications. Full recovery may take several weeks to months, depending on the individual's age and overall health. Follow-up appointments monitor healing progress, assess functional recovery, and adjust treatment as needed. Most patients regain normal arm function with proper care.

Complications

Complications are rare with routine healing but may include delayed union, nonunion, or malunion if the fracture does not heal properly. Infection is not a concern with closed fractures, but stiffness or reduced range of motion may occur if rehabilitation is insufficient. Persistent pain or swelling should be evaluated to rule out other issues.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed to prevent re-injury
• Use protective gear during sports or work that involves forearm stress
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Perform gentle range-of-motion exercises as directed to preserve mobility
• Follow healthcare provider recommendations for weight-bearing and activity restrictions

When to Seek Professional Help

Seek medical attention if you experience increasing pain, swelling, or bruising; loss of sensation or circulation in the hand; or difficulty moving the wrist or fingers. These symptoms may indicate a complication requiring prompt evaluation.

Tips for Medical Coders

Document the encounter as a "subsequent" visit for a closed fracture with routine healing. Ensure clinical notes specify the fracture type (nondisplaced segmental), location (shaft of radius, left arm), and healing status (routine). Code S52.365D is appropriate when the fracture is closed, healing without complications, and the encounter is for follow-up care. Verify that prior encounters or documentation support the "subsequent" designation.
