Code Description

ICD-10 M84.353 is a billable code used to indicate a diagnosis of stress fracture, unspecified femur.

Key Diagnostic Point:

A stress fracture of the femur is a small crack in the bone that occurs due to repetitive force or overuse, often seen in athletes or individuals with increased physical activity. Unlike acute fractures, stress fractures develop gradually and may not be immediately apparent on standard X-rays. The femur, being the longest and strongest bone in the body, can still be susceptible to stress fractures, particularly in its mid-shaft region. Risk factors for stress fractures include low bone density, osteoporosis, and certain metabolic bone disorders that affect bone strength and resilience. Patients may present with localized pain, swelling, and tenderness along the femur, which typically worsens with activity and improves with rest. Diagnosis often involves imaging studies such as MRI or bone scans, which can detect stress fractures that are not visible on X-rays. Treatment generally includes rest, modification of activities, and in some cases, physical therapy to strengthen surrounding muscles and improve bone health. Monitoring bone density and addressing any underlying metabolic issues is crucial for preventing future fractures.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of stress fractures, improving the ability to capture data on bone health and related conditions. This specificity aids in better tracking of treatment outcomes and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of stress fractures, improving the ability to capture data on bone health and related conditions. This specificity aids in better tracking of treatment outcomes and resource allocation.
