What This Code Means

A chronic bone infection of the left thighbone (femur) that developed from bacteria spreading through the bloodstream.

Coding Tips

• •Verify left femur is explicitly documented in the medical record
• •The femur is a weight-bearing bone, so document any functional limitations or mobility issues

Clinical Significance

Chronic hematogenous osteomyelitis of the left femur is a severe bone infection that significantly impacts the patient's ability to bear weight and ambulate. The femur's critical role in mobility makes this condition particularly debilitating, often requiring extensive medical management and rehabilitation services.

Documentation Requirements

• ✓Confirmation of chronic nature (minimum 6 weeks duration or recurrence)
• ✓Evidence of hematogenous origin (bloodstream seeding)
• ✓Specific documentation of left femur involvement
• ✓Imaging studies demonstrating bone infection or destruction
• ✓Laboratory markers supporting chronic infection (ESR, CRP trends)
• ✓Functional assessment including mobility and weight-bearing status
• ✓Documentation of antibiotic therapy duration and effectiveness
• ✓Assessment of complications such as pathological fractures
