S82.225N Nondisplaced transverse fracture of shaft of left tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

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

Summary

A nondisplaced transverse fracture of the shaft of the left tibia is a break that runs horizontally across the main portion of the tibia (shinbone) in the left leg, where the bone fragments remain aligned. This code applies to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) with nonunion, meaning the fracture has not healed properly after an initial injury. Open fractures involve skin penetration, and nonunion indicates a failure of the bone to fuse within the expected timeframe.

Causes

Nondisplaced transverse fractures of the tibial shaft commonly result from direct trauma, such as falls, motor vehicle accidents, or high-impact injuries. Open fractures (type IIIA, IIIB, or IIIC) occur when the fracture site communicates with the external environment, often due to severe trauma. Nonunion may develop from inadequate initial treatment, poor blood supply, infection, or excessive movement at the fracture site during healing.

Risk Factors

• Severe trauma or high-energy injuries.
• Open fracture types IIIA, IIIB, or IIIC, which increase infection risk.
• Poor blood supply to the fracture site.
• Inadequate immobilization or premature weight-bearing.
• Underlying conditions like diabetes or smoking, which impair healing.
• Previous fractures or surgeries in the same area.

Symptoms

• Persistent pain at the fracture site, often worsening with activity.
• Swelling, bruising, or tenderness along the shin.
• Difficulty bearing weight or walking.
• Possible signs of infection, such as redness, warmth, or drainage (in open fractures).
• Visible deformity or instability if nonunion is severe.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a review of the patient’s history and mechanism of injury. Imaging studies, such as X-rays, CT scans, or MRIs, are used to assess the fracture alignment, identify nonunion, and evaluate for signs of infection or open wound involvement. Additional tests, like blood work or wound cultures, may be performed to rule out infection in open fractures.

Treatment Options

Treatment focuses on promoting bone healing and addressing nonunion. Options may include surgical intervention, such as internal fixation with plates or screws, bone grafting, or external fixation devices. Antibiotics are often required for open fractures to prevent or treat infection. Physical therapy is typically recommended to restore function and strength once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of infection, and the success of treatment. Nonunion may require extended healing time or additional procedures. Regular follow-up appointments with imaging studies are necessary to monitor progress. Most patients can expect gradual improvement, but full recovery may take several months to a year, especially with complex open fractures.

Complications

• Infection, particularly in open fractures.
• Delayed or failed healing (nonunion).
• Nerve or vascular damage.
• Chronic pain or instability.
• Post-traumatic arthritis in the affected leg.
• Need for additional surgeries.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow weight-bearing restrictions and immobilization guidelines.
• Maintain a healthy diet rich in calcium and vitamin D to support bone healing.
• Quit smoking, as it impairs bone healing.
• Use protective gear during sports or high-risk activities to prevent injuries.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe pain, swelling, or deformity.
• Signs of infection, such as fever, redness, or drainage.
• Numbness, tingling, or loss of circulation in the foot.
• Inability to bear weight or walk.

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) with nonunion of the left tibial shaft. Documentation must clearly indicate the fracture type, the presence of nonunion, and that this is a subsequent encounter (not initial). Coders should verify the fracture’s alignment (nondisplaced) and ensure the open fracture classification (IIIA, IIIB, or IIIC) is supported by clinical notes.
