M86.061

HCC Category Mapping

What This Code Means

A bone infection in the right shin bones (tibia and fibula) caused by bacteria spreading through the bloodstream.

Coding Tips

• •This code includes both the tibia and fibula of the right leg; do not use if only one bone is affected
• •Verify right side is documented; use M86.062 for left-sided infection

Clinical Significance

Acute hematogenous osteomyelitis of the right tibia and fibula represents a severe bloodstream-disseminated infection requiring immediate intervention to prevent complications such as growth disturbances, chronic infection, or sepsis. The dual bone involvement increases complexity and treatment duration compared to single-bone infections.

Documentation Requirements

• ✓Documentation of osteomyelitis as acute and hematogenous in origin
• ✓Specific identification of right tibia and fibula involvement
• ✓Clinical presentation consistent with bone infection (pain, fever, swelling, inability to bear weight)
• ✓Imaging studies confirming osteomyelitis in tibia and/or fibula bones
• ✓Laboratory markers supporting infection (elevated ESR, CRP, leukocytosis)
• ✓Blood culture results if available to identify causative organism
• ✓Documentation of treatment response and antibiotic sensitivity
• ✓Assessment of functional impact on ambulation or weight-bearing
