S72.145M Nondisplaced intertrochanteric fracture of left femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

Nondisplaced intertrochanteric fracture of left femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A nondisplaced intertrochanteric fracture of the left femur is a break in the upper thigh bone, specifically between the greater and lesser trochanters, where the bone fragments remain aligned. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "open fracture type I or II" means the fracture communicates with the external environment through a skin wound with minimal or moderate soft tissue damage. "Nonunion" refers to the failure of the bone to heal properly after an extended period. This condition requires ongoing care to address both the unhealed fracture and the open wound.

Causes

Intertrochanteric fractures often result from trauma, such as falls or direct impact to the hip. In older adults, weakened bones due to osteoporosis are a common contributing factor. The open nature of the fracture typically arises from the same traumatic event that causes the bone break, with the skin wound resulting from the force of the injury. Nonunion may occur due to inadequate stabilization, poor blood supply to the bone, infection, or other factors that impede healing.

Risk Factors

• Advanced age, particularly in individuals over 65
• Osteoporosis or other bone-weakening conditions
• History of previous fractures
• Sedentary lifestyle or reduced bone density
• Traumatic events such as falls or high-impact injuries
• Poor blood supply to the fracture site
• Infection or other complications affecting healing

Symptoms

• Persistent pain in the hip or groin area
• Inability to bear weight on the left leg
• Swelling and bruising around the hip
• Visible or palpable wound at the fracture site
• Limited mobility or discomfort with movement
• Possible signs of nonunion, such as persistent pain or instability

Diagnosis

Diagnosis involves a physical examination to assess pain, mobility, and wound status, followed by imaging tests such as X-rays to visualize the fracture and check for nonunion. Additional imaging like CT scans or MRI may be used for detailed assessment of the fracture site and surrounding tissues. Laboratory tests may be performed to evaluate for infection or other complications.

Treatment Options

• Surgical intervention to stabilize the fracture and promote healing, such as internal fixation with screws or plates
• Wound care to manage the open fracture, including cleaning and dressing changes
• Antibiotics if infection is present or suspected
• Physical therapy to restore mobility and strength once healing progresses
• Possible bone grafting or other procedures to address nonunion

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the patient's overall health. Nonunion may require additional interventions, and open fractures carry a risk of infection. Regular follow-up appointments are necessary to monitor healing, assess for complications, and adjust treatment as needed. Recovery may take several months, with ongoing rehabilitation to restore function.

Complications

• Nonunion or delayed healing of the fracture
• Infection at the fracture site or wound
• Malunion (improper healing of the bone)
• Avascular necrosis (loss of blood supply to the bone)
• Chronic pain or instability
• Limited mobility or functional impairment

Lifestyle & Prevention

• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Engage in weight-bearing exercises to strengthen bones
• Use assistive devices like canes or walkers to prevent falls, especially in older adults
• Address osteoporosis or other bone conditions with appropriate medical management
• Follow post-treatment instructions carefully to support healing and reduce complications

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or visible wound changes at the fracture site, or if you notice signs of infection such as fever, redness, or drainage. Contact your healthcare provider if pain worsens, mobility decreases, or you have concerns about healing progress during follow-up care.

Tips for Medical Coders

When coding for S72.145M, ensure documentation supports the subsequent encounter status, the open fracture type (I or II), and the presence of nonunion. Verify that the fracture is specifically of the left femur and that the encounter is for treatment of the nonunion following an open fracture. Documentation should clearly indicate the type of open fracture and the reason for the subsequent visit (e.g., evaluation of nonunion, wound care, or adjustment of treatment).
