S72.059M Unspecified fracture of head of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Unspecified fracture of head of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Summary

An unspecified fracture of the head of the femur, with a subsequent encounter for an open fracture type I or II and nonunion, involves a break in the upper portion of the thigh bone affecting the femoral head (the ball-shaped top of the femur). This type of fracture occurs near the hip joint and is classified as open (compound) when the bone fragment pierces the skin, exposing the fracture site. Nonunion indicates the fracture has not healed properly after an extended period. This code is used for follow-up care of an open fracture that has failed to unite, requiring ongoing management to address both the fracture and the open wound.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Open fractures may result from trauma that disrupts the skin and underlying tissues. Nonunion can occur due to inadequate immobilization, poor blood supply, infection, or severe displacement of the fracture fragments.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Conditions that impair wound healing or increase fracture risk
• Smoking or poor nutrition, which can hinder bone healing

Symptoms

• Persistent hip or groin pain, often severe
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Visible wound or open fracture site (if still present)
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Possible signs of infection, such as redness, warmth, or drainage

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and determine if nonunion is present. Assessment of the open wound for signs of infection or healing. Evaluation of the patient’s medical history to identify factors contributing to nonunion.

Treatment Options

Surgical intervention to stabilize the fracture, such as internal fixation or hip replacement, may be necessary to promote healing. Management of the open wound, including debridement and antibiotics if infection is present. Bone grafting or other procedures to stimulate bone growth in cases of nonunion. Physical therapy to restore mobility and strength once the fracture shows signs of healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of infection, and the patient’s overall health. Nonunion may require extended treatment and rehabilitation. Regular follow-up appointments are essential to monitor healing, assess for complications, and adjust treatment as needed. Long-term mobility and function may be affected, particularly if the fracture does not heal properly.

Complications

• Infection at the fracture site or open wound
• Chronic pain or arthritis in the hip joint
• Persistent nonunion requiring additional surgery
• Leg length discrepancy or deformity
• Reduced mobility or disability
• Nerve or blood vessel damage

Lifestyle & Prevention

• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Engage in weight-bearing exercises to strengthen bones, as recommended by a healthcare provider.
• Use assistive devices, such as canes or walkers, to reduce fall risk, especially in older adults.
• Avoid high-impact activities that increase fracture risk until cleared by a healthcare provider.
• Quit smoking and limit alcohol consumption, as both can impair bone healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or visible signs of an open fracture. Contact your healthcare provider if you notice increased swelling, redness, warmth, or drainage from the wound, as these may indicate infection. Follow up regularly with your provider to monitor healing and address any concerns about nonunion or complications.

Tips for Medical Coders

This code is used for a subsequent encounter for an open fracture type I or II of the femoral head with nonunion. Document the fracture type (open I or II), the presence of nonunion, and the encounter type (subsequent) clearly in the medical record. Ensure the code aligns with the patient’s current clinical status and treatment plan. Verify that the fracture site and type are accurately described to support appropriate coding.
