S72.326J Nondisplaced transverse fracture of shaft of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Open Fracture Type IIIA, IIIB, or IIIC with Delayed Healing (ICD-10 Code: S72.326J)

Summary

A nondisplaced transverse fracture of the femur shaft is a break in the long, central portion of the thigh bone where the fracture line runs horizontally across the bone, and the bone fragments remain aligned without separation. This type of fracture involves the diaphysis (main structural part) of the femur. The code S72.326J specifies a subsequent encounter for an open fracture type IIIA, IIIB, or IIIC, indicating the fracture communicates with the external environment through a large or contaminated wound, and healing is delayed. The fracture may be associated with soft tissue injury or instability, though displacement is absent.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational forces or axial loading (e.g., during sports or industrial injuries) can also cause this type of break. Open fractures occur when the trauma is severe enough to pierce the skin, exposing the fracture site to the external environment. Delayed healing may result from factors like infection, poor blood supply, 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.
• Open fractures with contamination or extensive soft tissue damage.

Symptoms

• Sharp, localized pain in the thigh.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Possible numbness or tingling if nerve involvement occurs.
• Visible wound or open area at the fracture site (for open fractures).
• Prolonged healing time or persistent pain indicating delayed union.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests, such as X-rays or CT scans, to confirm the fracture type and assess healing progress. Evaluation of the open wound for contamination or infection. Assessment of soft tissue damage and vascular status. Review of prior treatment and healing history to determine if healing is delayed.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Surgical intervention, such as internal fixation, to align and stabilize the bone if needed.
• Wound care for open fractures, including debridement and antibiotics to prevent infection.
• Pain management with medications.
• Physical therapy to restore mobility and strength once healing allows.
• Monitoring for signs of infection or complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the open fracture, extent of soft tissue damage, and response to treatment. Delayed healing may require extended immobilization or additional interventions. Regular follow-up appointments with imaging to assess healing progress are essential. Full recovery may take several months, with potential for long-term mobility or strength limitations depending on the injury.

Complications

• Infection at the fracture site or open wound.
• Delayed or nonunion of the fracture.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Malalignment or deformity if healing is incomplete.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions.
• Maintain a healthy diet rich in calcium and vitamin D to support bone healing.
• Practice good wound care if an open fracture is present.
• Use protective equipment during sports or high-risk activities.
• Address underlying conditions like osteoporosis to reduce fracture risk.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or inability to move the leg. Contact a healthcare provider if the wound shows signs of infection (e.g., redness, pus, fever) or if healing does not progress as expected. Report persistent pain, numbness, or changes in limb function during follow-up.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), location (shaft of unspecified femur), encounter type (subsequent), and open fracture classification (IIIA, IIIB, or IIIC) with delayed healing. Ensure the open wound characteristics and healing status are clearly recorded to support the code. Verify that the encounter is subsequent (not initial) and that delayed healing is explicitly noted.
