S82.436H Nondisplaced oblique fracture of shaft of unspecified fibula, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced oblique fracture of shaft of unspecified fibula, subsequent encounter for open fracture type I or II with delayed healing

Summary

This condition describes a break in the shaft of the fibula (one of the two lower leg bones) with an oblique (angled) fracture line. The bone fragments remain aligned (nondisplaced), and the fracture is classified as open (type I or II), meaning the skin is breached but the wound is typically small and clean. This is a subsequent encounter, indicating follow-up care for a fracture that is healing more slowly than expected.

Causes

Direct trauma to the lower leg, such as from falls, sports injuries, or motor vehicle accidents. Twisting injuries during physical activity can also cause this type of fracture.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or weakened bone density.
• Previous fractures or bone-related conditions.

Symptoms

• Pain, swelling, or tenderness along the leg.
• Difficulty bearing weight or walking.
• Bruising or discoloration around the injury site.
• Possible open wound (type I or II) at the fracture site.
• Prolonged healing time compared to typical recovery.

Diagnosis

Physical examination by a healthcare professional to assess tenderness, swelling, and wound characteristics. Imaging tests, such as X-rays, to confirm the fracture type, location, and alignment. Evaluation of the open wound to determine its type (I or II). Assessment of healing progress to identify delayed healing.

Treatment Options

• Immobilization using a cast or brace to ensure the bone heals correctly.
• Pain management with medications like NSAIDs.
• Physical therapy to restore mobility and strength once healing progresses.
• Monitoring for signs of infection or complications related to the open fracture.
• Possible additional interventions if healing remains delayed.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and adherence to treatment. Follow-up appointments are crucial for monitoring healing progression through imaging and physical assessments. Delayed healing may require extended immobilization or additional interventions.

Complications

• Infection at the open fracture site.
• Nonunion or malunion of the fracture.
• Chronic pain or reduced mobility.
• Nerve or vascular damage in severe cases.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through proper nutrition and exercise.
• Follow healthcare provider recommendations for weight-bearing restrictions.

When to Seek Professional Help

Seek immediate care if experiencing increased pain, swelling, redness, or discharge from the wound. Contact a healthcare provider if healing does not progress as expected or if new symptoms develop.

Tips for Medical Coders

Document the fracture type (open I or II), subsequent encounter status, and evidence of delayed healing. Ensure clinical notes specify the fracture's alignment (nondisplaced) and shaft location of the unspecified fibula. Include details on wound characteristics and healing progress to support coding accuracy.
