Coding Tips

• •Document all affected sites in the medical record to justify the use of this multiple sites code

This condition suggests compromised immune status, carries extremely high risk for treatment failure, and requires intensive multidisciplinary management with significant impact on patient morbidity and mortality.

• ✓Clear evidence of multiple bone involvement
• ✓Specification of each anatomical site affected when possible
• ✓Evidence supporting chronic nature of infections
• ✓Comprehensive imaging studies of affected areas
• ✓Laboratory evidence of systemic inflammation or infection
• ✓Detailed treatment history including multiple antibiotic courses
