Which principle must be followed when coding for both severe sepsis and localized infection?

When coding for both severe sepsis and a localized infection, it is essential to select options based on the principle of documenting each diagnosis in a way that reflects the patient's condition accurately. Coding in a sequence based on severity allows healthcare providers and payers to understand the full clinical picture, prioritizing the most critical aspects of the patient's health status.

Severe sepsis represents a life-threatening condition that arises from an infection, while localized infections indicate areas of infection which might not be as severe on their own. However, both conditions are significant to the patient's care and treatment plan. By coding both diagnoses, providers ensure that the severity of the patient's condition is well represented, supporting appropriate treatment and reimbursement.

This approach highlights the complexity of the patient's situation, where multiple conditions are contributing to their health status. It also aligns with coding guidelines that advocate for comprehensive documentation of a patient's conditions.
