S82.224N Nondisplaced transverse fracture of shaft of right tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Nondisplaced transverse fracture of shaft of right tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

A nondisplaced transverse fracture of the shaft of the right tibia is a break that runs horizontally across the main portion of the tibia (shinbone) in the right leg, where the bone fragments remain aligned. This fracture is classified as an open fracture type IIIA, IIIB, or IIIC, meaning the overlying skin is broken and the wound is severe with significant contamination or tissue loss. The term "nonunion" indicates the fracture has failed to heal properly after an extended period. This is a subsequent encounter, meaning it represents follow-up care for an established, healing-compromised fracture.

Causes

Nondisplaced transverse fractures of the tibial shaft commonly occur due to direct trauma, such as falls, motor vehicle accidents, or sports injuries. High-energy impacts, like those from contact sports or industrial accidents, can also cause these injuries. Open fractures occur when the trauma is severe enough to break the skin, exposing the bone to the external environment. Nonunion may result from inadequate initial treatment, poor blood supply to the bone, infection, or excessive movement at the fracture site during healing.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Previous lower leg injuries.
• Age-related bone density loss, particularly in older adults.
• Lack of protective gear during physical activities.
• Smoking or poor nutrition, which can impair bone healing.
• Infections at the fracture site.

Symptoms

• Persistent pain at the fracture site, often worsening with activity.
• Swelling, bruising, or tenderness along the shin that does not improve over time.
• Difficulty bearing weight or walking, even with support.
• Visible deformity or misalignment in severe cases.
• Possible drainage or wound opening if the fracture is open.
• Limited range of motion in the ankle or knee.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a review of the patient’s medical history and mechanism of injury. Physical examination assesses pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture type, alignment, and presence of nonunion. Advanced imaging, like CT scans or MRIs, may be ordered to evaluate bone healing and soft tissue damage. Laboratory tests, including blood work, may be performed to check for infection or nutritional deficiencies affecting healing.

Treatment Options

Treatment focuses on promoting bone healing and managing the open fracture. Non-surgical options may include immobilization with a cast or brace, pain management, and antibiotics to prevent or treat infection. Surgical intervention, such as internal fixation with plates or screws, bone grafting, or external fixation, may be necessary to stabilize the fracture and encourage union. Wound care is critical for open fractures to prevent infection. Physical therapy is often recommended to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the patient’s overall health. Nonunion fractures may require additional interventions, such as surgery or bone stimulation, to achieve healing. Follow-up care is essential to monitor progress, adjust treatment plans, and address complications. Regular imaging and clinical assessments help track bone healing and functional recovery. Long-term outcomes may include residual pain, stiffness, or reduced mobility, particularly if healing is delayed.

Complications

• Infection at the fracture site or wound.
• Delayed or failed healing (nonunion or malunion).
• Nerve or blood vessel damage.
• Chronic pain or arthritis in the affected joint.
• Limited mobility or functional impairment.
• Need for additional surgeries.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs bone healing.
• Use protective gear during sports or work to reduce injury risk.
• Maintain a healthy weight to minimize stress on the bones.
• Attend all follow-up appointments and adhere to treatment plans.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe or worsening pain.
• Increased swelling, redness, or drainage from the wound.
• Fever or signs of infection.
• Sudden inability to bear weight or move the leg.
• New or worsening deformity.

Tips for Medical Coders

This code represents a subsequent encounter for an open fracture type IIIA, IIIB, or IIIC of the right tibial shaft with nonunion. Document the fracture type (IIIA, IIIB, or IIIC), the presence of nonunion, and the fact that this is a follow-up visit. Ensure the encounter is coded as subsequent (not initial) and that the open fracture classification is clearly documented. Note that nonunion implies the fracture has not healed after a typical recovery period, and this should be supported by clinical findings or imaging.
