S72.034M Nondisplaced midcervical fracture of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced midcervical fracture of right femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A nondisplaced midcervical fracture of the right femur is a break in the middle portion of the femoral neck (the region connecting the femoral head to the shaft) on the right side, where the bone fragments remain in their normal alignment. This code specifies a subsequent encounter for an open fracture type I or II with nonunion, indicating the fracture has not healed properly after an initial injury where the skin was breached but the wound was limited. Management focuses on addressing the nonunion and any residual open wound complications.

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 the same mechanisms, with the skin being penetrated by the fracture or an external object. Nonunion can occur due to inadequate stabilization, poor blood supply, infection, or excessive movement at the fracture site.

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)
• Open fractures may be more likely in cases involving significant trauma or penetrating injuries.
• Factors contributing to nonunion include smoking, diabetes, or inadequate initial treatment.

Symptoms

• Persistent hip or groin pain
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Possible signs of nonunion, such as persistent pain or instability
• Open wound remnants or drainage (if present)

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and determine nonunion. Assessment of the open wound (if present) for signs of infection or healing. Evaluation of blood supply and bone healing potential through clinical and imaging findings.

Treatment Options

• Surgical intervention, such as internal fixation or bone grafting, to promote union
• Wound care for any residual open fracture site
• Pain management and physical therapy to restore function
• Monitoring for infection or other complications
• Possible use of bone stimulators to enhance healing

Prognosis and Follow-Up

Prognosis depends on the success of treatment and resolution of nonunion. Follow-up imaging is typically required to assess bone healing. Long-term monitoring may be necessary to ensure proper alignment and function. Complications like infection or persistent nonunion can affect recovery.

Complications

• Nonunion or delayed union
• Infection of the open fracture site
• Avascular necrosis of the femoral head
• Post-traumatic arthritis
• Chronic pain or instability
• Need for additional surgical interventions

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Maintain bone health through diet and exercise (e.g., calcium, vitamin D)
• Use protective measures during high-risk activities
• Follow post-operative care instructions to support healing
• Attend all follow-up appointments to monitor progress

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, or signs of infection (e.g., fever, increased swelling, drainage). Contact a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

This code is used for a subsequent encounter of a nondisplaced midcervical fracture of the right femur with nonunion, specifically for open fracture type I or II. Documentation should clearly indicate the fracture type, nonunion status, and that this is a subsequent encounter. Ensure alignment with the ICD-10-CM guidelines for fracture coding and nonunion specifications.
