Code Description

ICD-10 M84.452 is a billable code used to indicate a diagnosis of pathological fracture, left femur.

Key Diagnostic Point:

A pathological fracture of the left femur occurs when the bone breaks due to underlying conditions that weaken the bone structure, rather than from a traumatic injury. Common causes include osteoporosis, metastatic cancer, or other bone density disorders. Osteoporosis, characterized by decreased bone mass and deterioration of bone tissue, significantly increases the risk of fractures, particularly in older adults. In patients with osteoporosis, even minor falls or stresses can lead to fractures. The left femur, being one of the largest and strongest bones in the body, can still succumb to these conditions, resulting in significant morbidity. Diagnosis typically involves imaging studies such as X-rays or MRIs to confirm the fracture and assess the underlying bone quality. Treatment may include surgical intervention, such as fixation or replacement, alongside management of the underlying condition to prevent future fractures. Proper documentation of the fracture's cause, the patient's bone health status, and any relevant comorbidities is essential for accurate coding and reimbursement.

Frequently Asked Questions

What is the difference between a pathological fracture and a traumatic fracture?

A pathological fracture occurs due to underlying bone disease or weakness, while a traumatic fracture results from an external force or injury. Proper documentation is essential to differentiate between the two for accurate coding.
