A40.9

HCC Category Mapping

What This Code Means

A serious bloodstream infection caused by streptococcal bacteria where the specific type of streptococcus has not been identified or documented. This is a life-threatening condition where bacteria have entered the blood and are multiplying throughout the body.

Coding Tips

• •Use this code only when the streptococcal organism is not further specified; if the specific streptococcal type (Group A, Group B, pneumococcal, etc.) is documented, use the more specific A40.0-A40.8 codes instead
• •Sepsis codes require documentation of systemic inflammatory response; ensure the clinical record clearly indicates sepsis diagnosis and consider querying the provider if only bacteremia or infection is documented without sepsis criteria

Clinical Significance

Streptococcal sepsis, unspecified, is used when documentation confirms streptococcal bloodstream infection but does not specify the streptococcal group or species. While it maps to the same HCC as specified codes, it represents suboptimal documentation specificity and may trigger coding quality audits.

Documentation Requirements

• ✓Blood cultures positive for Streptococcus species (group/species not further specified)
• ✓Clinical documentation of sepsis criteria met
• ✓Attempt to query the provider for specific streptococcal group or species identification
• ✓Severity and organ dysfunction assessment
• ✓Source of infection if identifiable
