S52.325F Nondisplaced transverse fracture of shaft of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Nondisplaced transverse fracture of shaft of left radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Summary

A nondisplaced transverse fracture of the shaft of the left radius is a horizontal break in the long, outer bone of the forearm (radius) where the bone fragments remain aligned. This specific code applies to a subsequent encounter for an open fracture (types IIIA, IIIB, or IIIC) with routine healing, indicating the fracture is in the healing phase after an initial injury that involved a break in the skin and required management for infection risk. The injury may affect arm function depending on the severity of associated soft tissue damage and the healing process.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving twisting forces at the wrist or elbow. High-impact events like motor vehicle collisions or sports injuries can also cause the bone to break in a transverse pattern. The open fracture classification (IIIA, IIIB, or IIIC) indicates varying degrees of soft tissue damage and contamination at the time of injury.

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
• Conditions that impair wound healing (e.g., diabetes, vascular disease)

Symptoms

• Sustained pain at the fracture site during healing
• Swelling, bruising, or tenderness around the forearm
• Difficulty moving the arm or wrist (may improve with healing)
• Possible residual deformity or limited range of motion
• Numbness or tingling in the hand or fingers (if nerve involvement occurred)
• Signs of routine healing (e.g., reduced swelling, callus formation)

Diagnosis

Diagnosis involves a physical examination to assess healing progress, including checking for tenderness, range of motion, and signs of infection. Imaging tests like X-rays are typically used to confirm the fracture is nondisplaced and healing as expected. Documentation should note the open fracture type (IIIA, IIIB, or IIIC) and the routine healing status to support the code assignment.

Treatment Options

Treatment focuses on monitoring healing and managing symptoms. This may include immobilization (e.g., cast or splint) if needed, pain management, and physical therapy to restore function. Routine follow-up ensures the fracture heals without complications, and any signs of infection or delayed healing are addressed promptly.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though full recovery may take several weeks to months. Follow-up appointments are essential to assess healing progress, adjust treatment, and guide rehabilitation. Most patients regain full arm function, but stiffness or minor limitations may persist depending on the initial injury severity.

Complications

• Infection (if the open fracture was severe)
• Delayed or nonunion of the fracture
• Nerve or vascular damage (if present initially)
• Chronic pain or stiffness
• Malunion (rare with nondisplaced fractures)
• Limited range of motion in the wrist or elbow

Lifestyle & Prevention

• Avoid high-impact activities until fully healed
• Use protective gear during sports or work
• Maintain bone health with calcium and vitamin D (if applicable)
• Follow rehabilitation guidelines to restore strength and mobility
• Report any new pain, swelling, or signs of infection immediately

When to Seek Professional Help

Seek medical attention if you experience increasing pain, swelling, redness, or drainage at the fracture site; fever; numbness or tingling that worsens; or difficulty moving the arm. These may indicate infection, delayed healing, or other complications requiring intervention.

Tips for Medical Coders

This code (S52.325F) is used for a subsequent encounter of a nondisplaced transverse fracture of the left radius shaft with an open fracture type IIIA, IIIB, or IIIC, where healing is routine. Documentation must specify the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing. Ensure the encounter is classified as "subsequent" (not initial) and that the fracture is nondisplaced. Avoid using this code for closed fractures or initial encounters.
