S52.136H Nondisplaced fracture of neck of unspecified radius, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced fracture of neck of unspecified radius, subsequent encounter for open fracture type I or II with delayed healing
• Medical term: S52.136H

Summary

A nondisplaced fracture of the neck of the unspecified radius is a break in the radius bone near the wrist where the bone fragments remain in their normal alignment. This code represents a subsequent encounter for an open fracture type I or II (where the fracture communicates with the external environment) that is healing more slowly than expected. The "subsequent encounter" indicates ongoing care after the initial treatment phase, and "delayed healing" reflects a prolonged recovery timeline.

Causes

Nondisplaced fractures often result from trauma to the forearm, such as falls onto an outstretched hand, direct blows, or accidents. Open fractures occur when the broken bone pierces the skin or external forces create a wound at the fracture site. Delayed healing may stem from factors like infection, poor blood supply, or inadequate immobilization during initial treatment.

Risk Factors

• Osteoporosis or weakened bone density
• High-impact activities or sports with fall risks
• Advanced age, which may reduce bone resilience
• Previous fractures or bone health conditions
• Open fracture type I or II, which increases infection risk

Symptoms

• Persistent pain at the fracture site
• Swelling and tenderness in the forearm or wrist
• Possible open wound (for type I or II)
• Limited range of motion in the affected arm
• Prolonged healing timeline compared to typical recovery

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate alignment. Additional scans like CT or MRI may be ordered to assess bone healing and soft tissue damage. Clinical evaluation of the wound (for open fractures) and monitoring of healing progress are also critical.

Treatment Options

• Pain management with medications such as NSAIDs
• Immobilization with a cast or splint to support healing
• Wound care for open fractures to prevent infection
• Physical therapy to restore mobility and strength
• Possible surgical intervention if healing does not progress

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and overall health. Delayed healing may extend recovery time, but most fractures eventually heal with proper care. Follow-up appointments are necessary to monitor progress, adjust treatment, and address complications. Regular imaging may be used to track bone healing.

Complications

• Infection at the fracture site (especially with open fractures)
• Nonunion or malunion of the fracture
• Chronic pain or stiffness
• Nerve or blood vessel damage
• Reduced range of motion in the wrist or forearm

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports or activities with fall risks
• Maintain bone health through diet and exercise (e.g., calcium, vitamin D)
• Follow immobilization and wound care instructions carefully
• Attend all follow-up appointments to monitor healing

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Increased pain, swelling, or redness at the fracture site
• Signs of infection (e.g., fever, pus, warmth)
• Numbness or tingling in the hand or fingers
• Difficulty moving the wrist or forearm
• Worsening of the open wound

Tips for Medical Coders

This code (S52.136H) is used for a subsequent encounter of a nondisplaced fracture of the neck of the unspecified radius with an open fracture type I or II that is healing slowly. Documentation should specify the fracture type, encounter stage (subsequent), and evidence of delayed healing (e.g., imaging showing incomplete union over time). Ensure the open fracture classification (type I or II) and healing status are clearly documented to support code assignment.
