S72.045H Nondisplaced fracture of base of neck of left femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced fracture of base of neck of left femur, subsequent encounter for open fracture type I or II with delayed healing (S72.045H)

Summary

This condition involves a break in the upper portion of the left femur (thigh bone) at the base of the femoral neck, near the hip joint. The term "nondisplaced" indicates that the bone fragments remain in their normal anatomical position. The "open fracture type I or II" designation refers to a fracture where the skin is breached, with minimal or moderate soft tissue damage. The "subsequent encounter" and "delayed healing" modifiers indicate this is a follow-up visit for a fracture that is not progressing as expected in the healing process. This type of injury requires ongoing evaluation to guide management and monitor healing.

Causes

High-impact trauma, such as falls or motor vehicle accidents, is a common cause. In older adults, particularly those with weakened bone density (e.g., osteoporosis), fractures may occur from minor trauma or low-impact events. Direct force to the hip or thigh region can also result in this injury. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Advanced age, especially in individuals over 65
• Osteoporosis or other bone-weakening conditions
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Smoking or poor nutrition, which can impair healing
• Chronic conditions like diabetes or vascular disease

Symptoms

• Persistent or worsening hip or groin pain
• Swelling, bruising, or tenderness around the hip
• Inability to bear weight on the affected leg
• Visible wound or opening at the fracture site (for open fractures)
• Limited range of motion in the hip joint
• Possible signs of delayed healing, such as lack of improvement over time

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and evaluate healing progress. Assessment of the open wound (if present) to determine infection risk. Review of prior treatment and healing timeline to identify factors contributing to delayed healing.

Treatment Options

• Immobilization with a cast, brace, or traction to stabilize the fracture
• Surgical intervention, such as internal fixation, if healing is not progressing
• Wound care for open fractures to prevent infection
• Pain management with medications
• Physical therapy to restore mobility and strength once healing allows
• Nutritional support or supplements to promote bone healing

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the patient’s overall health, and adherence to treatment. Delayed healing may extend recovery time, requiring closer monitoring. Follow-up visits are essential to assess healing progress, adjust treatment, and address complications. Most patients eventually regain function, but recovery may be prolonged.

Complications

• Nonunion (failure of the bone to heal)
• Infection at the fracture site or wound
• Avascular necrosis (loss of blood supply to the femoral head)
• Chronic pain or arthritis in the hip joint
• Muscle atrophy or weakness from prolonged immobilization
• Need for additional surgery if healing does not occur

Lifestyle & Prevention

• Maintain a diet rich in calcium and vitamin D to support bone health
• Engage in weight-bearing exercises to strengthen bones
• Use assistive devices (e.g., canes, walkers) to prevent falls, especially in older adults
• Avoid high-risk activities that increase fracture risk
• Quit smoking, as it impairs bone healing
• Manage chronic conditions like diabetes to optimize healing

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or signs of infection (e.g., fever, increased redness, or drainage from the wound). Contact your healthcare provider if pain worsens, swelling persists, or you notice no improvement in healing over time.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (left femur), and the reason for the encounter (subsequent with delayed healing). Include details on the fracture’s healing status, any complications, and the type of care provided. Ensure the open fracture classification and delayed healing modifier are clearly supported by clinical notes to justify the code.
