S72.364K Nondisplaced segmental fracture of shaft of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced Segmental Fracture of Shaft of Right Femur, Subsequent Encounter for Closed Fracture with Nonunion (ICD-10 Code: S72.364K)

Summary

A nondisplaced segmental fracture of the right femur shaft involves a break in the long, central portion of the thigh bone with a separate, intermediate bone fragment, where the bone fragments remain aligned. This condition is classified as a subsequent encounter, indicating ongoing care after the initial treatment phase, and includes nonunion, meaning the fracture has failed to heal properly over time. The fracture is closed, with the overlying skin intact, but the lack of healing requires continued medical attention.

Causes

Such fractures often result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational forces or axial loading (e.g., during sports or industrial injuries) can also cause this type of break. Nonunion may develop due to inadequate immobilization, poor blood supply to the fracture site, infection, or underlying health conditions that impair healing.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.
• Smoking or poor nutrition, which can hinder bone healing.
• Certain medical conditions, such as diabetes or vascular disease.

Symptoms

• Persistent or recurrent pain at the fracture site.
• Swelling, bruising, or tenderness around the affected area.
• Inability to bear weight on the affected leg.
• Possible deformity or instability if the fracture shifts.
• Limited range of motion in the hip or knee.
• Crepitus (grinding sensation) with movement.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging studies, such as X-rays or CT scans, to evaluate the fracture site and confirm nonunion. Additional tests, like bone scans or MRI, may be used to assess blood flow and tissue viability. Review of prior treatment and healing progress is essential to determine the need for further intervention.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Surgical intervention, such as internal fixation with plates or screws, to promote healing.
• Bone grafting to stimulate bone growth and repair.
• Physical therapy to restore strength and mobility.
• Pain management with medications or other modalities.
• Monitoring for signs of infection or further complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Follow-up care is critical to assess healing progress, adjust treatment plans, and prevent long-term complications. Regular imaging and clinical evaluations help determine if additional interventions are needed. Most patients require ongoing monitoring to ensure the fracture eventually heals or stabilizes.

Complications

• Chronic pain or discomfort.
• Limited mobility or functional impairment.
• Increased risk of future fractures.
• Infection at the fracture site.
• Nerve or vascular damage.
• Malunion (improper healing) or delayed union.
• Need for additional surgeries.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective equipment during sports or high-risk activities.
• Follow post-treatment guidelines for weight-bearing and activity restrictions.
• Attend all scheduled follow-up appointments to monitor progress.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Sudden, severe pain or swelling.
• Inability to move the leg or bear weight.
• Signs of infection, such as fever, redness, or pus.
• Numbness, tingling, or changes in skin color below the fracture site.
• Worsening pain or new deformity.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the record specifies the fracture type (nondisplaced segmental), location (right femur shaft), and the presence of nonunion. Include details about prior treatments, current symptoms, and any interventions performed. Verify that the code aligns with the clinical documentation to reflect the ongoing nature of the condition and the need for continued care.
