S72.324H Nondisplaced transverse fracture of shaft of right femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Right Femur, Subsequent Encounter for Open Fracture Type I or II with Delayed Healing (ICD-10 Code: S72.324H)

Summary

A nondisplaced transverse fracture of the shaft of the right femur is a break in the long, central portion of the right thigh bone, where the fracture line runs horizontally across the bone and the bone fragments remain aligned. This type of fracture involves the diaphysis (main structural part) of the femur. The code specifies a subsequent encounter, meaning the patient is receiving follow-up care for an open fracture type I or II (a break in the skin with minimal contamination or soft tissue damage) that is healing more slowly than expected.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct force to the thigh. Rotational or axial loading injuries (e.g., during sports or industrial accidents) can also cause this type of break. The open fracture component suggests the trauma was severe enough to penetrate the skin, though the fracture remains nondisplaced. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.
• Smoking or poor nutrition, which can impair bone healing.
• Certain medical conditions (e.g., diabetes) that affect circulation or immune function.

Symptoms

• Persistent or worsening pain at the fracture site, despite treatment.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Possible numbness or tingling if nerve involvement occurs.
• Delayed union (fracture not healing within the typical timeframe) or nonunion (fracture failing to heal).

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays or CT scans are used to evaluate the fracture site and check for signs of healing. Additional tests (e.g., blood work) may be ordered to rule out infection or underlying conditions affecting healing. The diagnosis confirms the fracture type, open status, and delayed healing.

Treatment Options

Treatment focuses on promoting healing and may include: immobilization with a cast or brace to stabilize the bone; pain management with medications; physical therapy to restore strength and mobility once healing progresses; and in some cases, surgical intervention (e.g., bone grafting or fixation) if healing does not improve. Follow-up imaging is used to monitor progress.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury, overall health, and adherence to treatment. Most fractures with delayed healing eventually heal with proper care, but recovery may take longer than typical. Regular follow-up appointments are necessary to assess healing and adjust treatment. Patients should avoid activities that stress the fracture site until cleared by a healthcare provider.

Complications

• Nonunion (fracture fails to heal).
• Infection at the fracture site or open wound.
• Nerve or blood vessel damage.
• Chronic pain or stiffness.
• Malalignment if the fracture displaces during healing.
• Prolonged immobility leading to muscle atrophy or joint stiffness.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs bone healing.
• Use protective equipment during sports or high-risk activities.
• Maintain a healthy weight to reduce stress on bones.
• Engage in low-impact exercises (e.g., swimming) to preserve mobility during recovery.

When to Seek Professional Help

Seek immediate medical attention if: pain worsens or is uncontrolled; swelling, redness, or drainage from the wound increases; numbness or tingling in the leg persists or worsens; or the leg cannot bear weight. Contact a healthcare provider if healing does not progress as expected or if symptoms return after improvement.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), location (shaft of right femur), open status (type I or II), and the reason for subsequent encounter (delayed healing). Ensure clinical notes specify the fracture’s alignment, open wound details, and evidence of delayed healing (e.g., imaging reports or provider assessments). The code S72.324H requires clear documentation of the fracture’s characteristics and the subsequent encounter context to support accurate coding.
