Code Description

ICD-10 M84.345 is a billable code used to indicate a diagnosis of stress fracture, left finger(s).

Key Diagnostic Point:

A stress fracture in the left finger(s) is a small crack in the bone that occurs due to repetitive force or overuse, rather than a single traumatic event. This condition is often seen in athletes or individuals who engage in repetitive hand movements. Stress fractures can arise from various factors, including low bone density, osteoporosis, and inadequate nutrition, which can compromise bone strength and integrity. In the case of the left finger(s), the fracture may involve the phalanges or metacarpals, leading to pain, swelling, and tenderness in the affected area. Diagnosis typically involves a thorough clinical evaluation, imaging studies such as X-rays or MRI, and assessment of the patient's history, including any underlying bone metabolism disorders. Treatment often includes rest, immobilization, and possibly physical therapy to restore function and prevent recurrence. Understanding the underlying causes of stress fractures, particularly in patients with osteoporosis or other bone density disorders, is crucial for effective management and prevention strategies.

  • Differentiating between stress fractures and other types of fractures
  • Identifying the specific location of the fracture within the finger(s)
  • Assessing the patient's history of bone density disorders
  • Understanding the implications of osteoporosis on fracture healing

Audit Risk Factors

  • Inadequate documentation of the fracture's cause
  • Failure to document underlying bone density disorders
  • Misclassification of the fracture type
  • Lack of imaging studies to support the diagnosis

Frequently Asked Questions

What is the difference between a stress fracture and a regular fracture?

A stress fracture is a small crack in the bone caused by repetitive force or overuse, while a regular fracture typically results from a single traumatic event. Stress fractures often occur in weight-bearing bones and may not be visible on initial X-rays.
