0.000What This Code Means
A long-term bone infection from bloodstream bacteria occurring in areas of the body other than the common sites like limbs.
Coding Tips
- •Specify the anatomical site in documentation when assigning this code
- •This is a catch-all code for less common locations of chronic hematogenous osteomyelitis
Clinical Significance
This code captures chronic hematogenous osteomyelitis occurring in anatomical sites not specified by other codes, such as vertebrae, pelvis, or ribs. These locations often present unique diagnostic and treatment challenges, potentially requiring specialized surgical approaches and prolonged antibiotic therapy.
Documentation Requirements
- ✓Documentation of chronic nature (>6 weeks duration or recurrent)
- ✓Evidence of hematogenous origin (bloodstream seeding)
- ✓Specific anatomical site not covered by standard extremity codes
- ✓Imaging confirmation of bone infection at the specified site
- ✓Laboratory studies supporting chronic infection
- ✓Assessment of functional impact specific to affected bone site
- ✓Treatment plan including site-specific considerations
- ✓Documentation ruling out other causes of bone pathology
Commonly Confused Codes
M86.60 — Other chronic osteomyelitis, unspecified site (lacks site specificity)M46.20 — Osteomyelitis of vertebra, unspecified site (vertebral-specific code)M86.48 — Chronic osteomyelitis with draining sinus, other site (has draining sinus)M86.18 — Other acute osteomyelitis, other site (acute phase)M89.9 — Disorder of bone, unspecified (non-infectious bone disorder)
