S52.355F Nondisplaced comminuted 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 comminuted fracture of shaft of radius, left arm, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
ICD-10 Code: S52.355F

Summary

A nondisplaced comminuted fracture of the shaft of the radius involves a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the bone is shattered into multiple pieces but the fragments remain in their original alignment. This injury is classified as an open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage, and is a subsequent encounter, meaning it follows initial treatment. The fracture is healing routinely, suggesting stable alignment and no complications. Management focuses on monitoring healing and addressing any residual soft tissue concerns.

Causes

This fracture typically results from high-impact trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving significant force (e.g., motor vehicle collisions, sports injuries). The open nature of the fracture (types IIIA, IIIB, or IIIC) arises from severe trauma that breaches the skin and causes extensive soft tissue damage, while the nondisplaced fragments remain in alignment.

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

• Persistent pain at the injury site, though reduced from initial trauma
• Swelling or bruising that may gradually improve
• Possible residual soft tissue changes from the open fracture
• Limited range of motion in the forearm or wrist
• Sensation of instability or discomfort during movement

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses pain, swelling, and range of motion. X-rays or CT scans verify the nondisplaced, comminuted nature of the fracture and confirm routine healing. Documentation of the open fracture type (IIIA, IIIB, or IIIC) and subsequent encounter status is critical for coding accuracy.

Treatment Options

Treatment focuses on monitoring healing and supporting recovery. This may include immobilization (e.g., a cast or brace) to protect the bone, pain management, and physical therapy to restore function. Wound care is managed based on the initial open fracture type, and follow-up imaging ensures the fracture remains aligned and heals without complications.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though recovery time depends on the extent of soft tissue damage. Follow-up appointments monitor healing progress, assess range of motion, and adjust treatment as needed. Most patients regain full function, but residual stiffness or weakness may occur.

Complications

• Delayed union or nonunion of the fracture
• Infection from the initial open fracture
• Chronic pain or stiffness in the forearm
• Nerve or vascular damage from the original trauma
• Reduced grip strength or mobility

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports or work to prevent falls
• Maintain bone health through diet and exercise to reduce fracture risk
• Follow post-injury rehabilitation guidelines to restore strength and mobility

When to Seek Professional Help

Seek care if you experience increasing pain, swelling, or redness; signs of infection (e.g., fever, pus); or new numbness or weakness in the hand or fingers. These may indicate complications requiring prompt intervention.

Tips for Medical Coders

Code S52.355F is used for a nondisplaced comminuted fracture of the left radius shaft with an open fracture type IIIA, IIIB, or IIIC, documented as a subsequent encounter with routine healing. Ensure documentation specifies the fracture type, limb (left), and healing status to support accurate coding. Verify that the encounter is subsequent (not initial) and that healing is routine, as these details are essential for correct code assignment.
