S72.301M Unspecified fracture of shaft of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Unspecified Fracture of Shaft of Right Femur, Subsequent Encounter for Open Fracture Type I or II with Nonunion

Summary

This condition refers to a fracture of the shaft (long, central part) of the right femur (thigh bone) where the specific type of fracture is not detailed. It is categorized as a subsequent encounter, meaning this is a follow-up visit for an open fracture type I or II (where the skin is broken with minimal soft tissue damage) that has failed to heal (nonunion). The unspecified nature indicates the fracture type was not further characterized.

Causes

Fractures of the femur shaft typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Open fractures occur when the bone pierces the skin or when a wound extends to the bone, often due to significant trauma. Nonunion may develop due to inadequate stabilization, poor blood supply, infection, or other factors that impede healing.

Risk Factors

• High-impact activities or trauma.
• Osteoporosis or bone-weakening conditions.
• Advanced age, which may reduce bone density.
• Prior history of fractures or bone abnormalities.
• Inadequate initial treatment or complications during healing.

Symptoms

• Persistent pain in the thigh region.
• Swelling, bruising, or tenderness at the fracture site.
• Inability to bear weight on the affected leg.
• Possible visible deformity or shortening of the leg.
• Delayed healing or lack of progress in fracture repair.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and confirm nonunion. Additional scans (e.g., CT or MRI) may be used if more detail is needed to evaluate healing or soft tissue involvement.

Treatment Options

• Surgical intervention (e.g., internal fixation with plates, screws, or rods) to stabilize the fracture and promote healing.
• Bone grafting to stimulate bone growth and repair.
• Antibiotics if infection is present.
• Immobilization with a cast or brace to support the healing process.
• Physical therapy to restore strength and mobility once healing progresses.

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 recovery can be prolonged. Regular follow-up visits and imaging are necessary to monitor healing and adjust treatment as needed.

Complications

• Persistent nonunion or delayed healing.
• Infection at the fracture site.
• Nerve or blood vessel damage.
• Malunion (healing in an incorrect position).
• Chronic pain or reduced mobility.

Lifestyle & Prevention

• Avoid high-impact activities that risk injury.
• Maintain bone health through diet and exercise.
• Use protective gear during sports or high-risk activities.
• Follow post-treatment instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or deformity, or if the leg cannot bear weight. 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 for an open fracture type I or II of the right femur shaft with nonunion. Document the encounter type (subsequent), fracture type (open I or II), and nonunion status clearly. Ensure the right femur and shaft location are specified, and the fracture is documented as unspecified.
