S72.465H Nondisplaced supracondylar fracture with intracondylar extension of lower end of left femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced supracondylar fracture with intracondylar extension of lower end of left femur, subsequent encounter for open fracture type I or II with delayed healing

Summary

This condition involves a fracture at the distal (lower) end of the left femur, extending from the supracondylar region (above the condyles) into the intracondylar area (within the condyles). The fracture disrupts the knee joint’s structural integrity, potentially affecting stability and function. The pattern includes both the metaphyseal region above the condyles and the articular surface of the condyles, with bone fragments remaining aligned (nondisplaced). It is classified as an open fracture type I or II (skin break with minimal contamination) and is a subsequent encounter, indicating ongoing care for delayed healing.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct force to the knee. Sports injuries involving sudden twisting or axial loading. Low-energy trauma in individuals with weakened bone density may also result in this fracture pattern.

Risk Factors

• Advanced age and associated bone density loss.
• Osteoporosis or other metabolic bone disorders.
• Participation in high-risk activities or contact sports.
• Prior history of knee or femur injuries.
• Conditions affecting bone strength, such as chronic steroid use.

Symptoms

• Severe knee pain and swelling.
• Bruising or visible deformity around the knee.
• Inability to bear weight or move the knee.
• Possible numbness or tingling if nerves are compressed.
• Persistent pain or swelling indicating delayed healing.

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays or CT scans to confirm the fracture pattern, displacement, and healing status. Documentation of the open fracture type (I or II) and evidence of delayed healing (e.g., lack of radiographic progression) is critical for coding.

Treatment Options

Treatment may include immobilization with a cast or brace, pain management, and close monitoring for healing. Surgical intervention could be considered if healing does not progress. Open fracture care involves wound management to prevent infection. Physical therapy may be recommended to restore function once healing allows.

Prognosis and Follow-Up

Prognosis depends on the fracture’s alignment, healing progress, and any complications. Delayed healing may extend recovery time, requiring ongoing monitoring. Follow-up appointments with imaging are typical to assess healing and adjust treatment as needed.

Complications

• Infection (especially with open fractures).
• Nonunion or malunion of the fracture.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a provider.
• Use protective gear during sports or high-risk activities.
• Maintain bone health through diet and exercise (if appropriate).
• Follow weight-bearing restrictions to support healing.

When to Seek Professional Help

Seek care if experiencing increased pain, swelling, redness, or drainage from the wound; inability to move the knee; or signs of infection (e.g., fever, chills). Persistent pain or lack of healing progress also warrants evaluation.

Tips for Medical Coders

Document the fracture’s location (left femur), displacement status (nondisplaced), extension (intracondylar), encounter type (subsequent), open fracture classification (type I or II), and evidence of delayed healing (e.g., clinical or radiographic findings) to support accurate coding. Ensure all elements of the code description are clearly documented in the medical record.
