What This Code Means

Death of bone tissue in the thighbone (femur) caused by previous trauma, but the specific side (left or right) is not specified or documented.

Coding Tips

• •Use this code only when laterality cannot be determined from documentation; query provider if possible to obtain specific side information
• •This is a less specific code; attempt to clarify whether the condition affects the right or left femur for more accurate coding

Clinical Significance

Unspecified femoral osteonecrosis following trauma indicates major bone pathology affecting primary weight-bearing function with significant implications for mobility and independence. This condition typically requires advanced orthopedic intervention and comprehensive rehabilitation planning.

Documentation Requirements

• ✓Documentation of femur involvement without specified laterality
• ✓Clear history of previous trauma to hip/thigh area
• ✓Evidence of osteonecrosis in femoral bone structures
• ✓Justification for unspecified laterality (bilateral involvement or unclear documentation)
• ✓Current mobility status and weight-bearing capacity
• ✓Functional assessment and pain evaluation
• ✓Treatment planning and surgical considerations
• ✓Impact on patient independence and daily functioning
