S52.334F Nondisplaced oblique fracture of shaft of right radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Nondisplaced oblique fracture of shaft of right radius, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
ICD-10 Code: S52.334F

Summary

A nondisplaced oblique fracture of the shaft of the right radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the fracture line runs at an angle across the bone and the bone fragments remain aligned. This code applies to a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, with routine healing. The fracture is considered open due to skin or soft tissue disruption, and the healing process is progressing without complications. Treatment during this phase focuses on monitoring healing and managing any residual soft tissue issues.

Causes

This fracture typically results from 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 an oblique pattern, with the open nature of the fracture resulting from the force of the injury piercing the skin. The subsequent encounter indicates ongoing care after the initial injury and treatment.

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 mild pain at the injury site during movement
• Minimal swelling or bruising as healing progresses
• Possible residual stiffness or limited range of motion in the wrist or forearm
• No visible bone protrusion (healing phase)
• Normal sensation in the hand (unless pre-existing nerve involvement)

Diagnosis

Diagnosis is based on clinical evaluation and imaging. A physical exam assesses pain, swelling, and range of motion. X-rays confirm the fracture type, alignment, and healing status. CT or MRI may be used to evaluate soft tissue damage or residual issues. The open fracture classification (IIIA, IIIB, or IIIC) is determined by the extent of soft tissue injury and contamination. Routine healing is confirmed by imaging showing progressive bone union without signs of infection or nonunion.

Treatment Options

Treatment during the subsequent encounter focuses on monitoring and supporting healing. This may include:

• Follow-up imaging to assess bone union
• Physical therapy to restore strength and range of motion
• Pain management as needed
• Wound care if residual soft tissue issues remain
• Activity modification to avoid re-injury
• Orthotic devices (e.g., splints) for support during healing

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, though recovery time varies. Most patients regain full function, but stiffness or minor strength deficits may persist. Follow-up appointments monitor healing progress, adjust treatment, and address any complications. Full recovery typically takes several weeks to months, depending on the fracture and individual factors.

Complications

• Delayed union or nonunion of the fracture
• Persistent infection (rare in routine healing)
• Chronic pain or stiffness
• Nerve or vascular damage (if present initially)
• Malalignment if healing is not optimal

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a provider
• Use protective gear during sports or work
• Maintain bone health with calcium and vitamin D (if applicable)
• Perform prescribed exercises to restore mobility
• Follow weight-bearing restrictions as advised

When to Seek Professional Help

Seek care if:

• Pain worsens or does not improve
• Swelling, redness, or drainage increases (signs of infection)
• Numbness, tingling, or weakness in the hand develops
• The arm cannot be used normally
• Healing stalls or symptoms return

Tips for Medical Coders

Use S52.334F for a subsequent encounter of a nondisplaced oblique fracture of the right radius shaft with an open fracture type IIIA, IIIB, or IIIC, where healing is routine. Document the fracture type, encounter stage (subsequent), and healing status clearly. Ensure the open fracture classification (IIIA, IIIB, or IIIC) is supported by clinical notes, as this impacts coding accuracy. Routine healing indicates no complications like infection or nonunion; if these occur, coding may change.
