What This Code Means

A bone infection in the thighbone (femur) caused by bacteria spreading through the bloodstream, but the specific side is not documented.

Coding Tips

• •Avoid this code if laterality can be determined; query provider for clarification
• •Document which femur is affected to ensure appropriate treatment planning

Clinical Significance

Acute hematogenous osteomyelitis represents a serious bloodstream-disseminated bone infection requiring immediate antibiotic therapy to prevent complications like sepsis, bone necrosis, or chronic infection. This condition significantly impacts patient mobility, quality of life, and carries substantial morbidity risk requiring intensive medical management.

Documentation Requirements

• ✓Clear documentation of osteomyelitis as acute and hematogenous (bloodstream origin)
• ✓Identification of femur as the affected bone
• ✓Clinical evidence of bone infection (bone pain, swelling, fever, elevated inflammatory markers)
• ✓Imaging findings supporting osteomyelitis (MRI, bone scan, or CT showing bone changes)
• ✓Laboratory evidence such as elevated ESR, CRP, or white blood cell count
• ✓Documentation that laterality (right/left) is unspecified or unknown
• ✓Exclusion of other causes of bone pathology
• ✓Treatment plan including antibiotic therapy duration and route
