S72.035Q Nondisplaced midcervical fracture of left femur, subsequent encounter for open fracture type I or II with malunion

Name of the Condition

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

Summary

A nondisplaced midcervical fracture of the left femur is a break in the middle portion of the femoral neck (the region connecting the femoral head to the shaft) on the left side, with the bone fragments remaining in their normal alignment. This code specifies a subsequent encounter for an open fracture type I or II with malunion, indicating the fracture has healed improperly and the overlying skin was breached but the wound is limited. Management focuses on addressing the malunion and monitoring for 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. Malunion can occur if the fracture heals in an abnormal position, often due to inadequate immobilization or poor blood supply.

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.
• Malunion risk increases with inadequate treatment, poor nutrition, or smoking.

Symptoms

• Persistent hip or groin pain, especially with weight-bearing
• Difficulty bearing 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 visible signs of prior open wound healing

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and malunion. Review of prior treatment and wound history to confirm open fracture type and healing status. Assessment of functional limitations and gait.

Treatment Options

• Pain management with analgesics or anti-inflammatories
• Physical therapy to improve strength and mobility
• Orthopedic evaluation for potential corrective surgery (e.g., osteotomy)
• Monitoring for complications related to malunion or prior open fracture
• Weight-bearing restrictions as advised by a healthcare provider

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Most patients experience improved symptoms with treatment, but some may have long-term mobility limitations. Regular follow-up with imaging and physical assessments is recommended to monitor healing and adjust management as needed.

Complications

• Chronic pain or arthritis in the hip joint
• Reduced mobility or gait abnormalities
• Increased risk of future fractures due to malunion or bone weakness
• Potential infection from prior open fracture (rare)
• Need for additional surgery to correct malunion

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D intake
• Engage in weight-bearing exercise to strengthen bones
• Use fall prevention strategies, especially in older adults
• Avoid high-risk activities without proper protection
• Quit smoking to improve bone healing

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, or signs of infection (e.g., fever, redness, drainage). Follow up with a healthcare provider if symptoms worsen or new limitations develop.

Tips for Medical Coders

Document the fracture location (midcervical, left femur), displacement status (nondisplaced), encounter type (subsequent), open fracture classification (type I or II), and malunion. Include details on prior treatment, wound status, and functional impact to support code assignment. Ensure alignment with clinical notes and imaging reports.
