Sepsis Due to a Localized Infection
A 45-year-old patient was admitted with mental status changes. She had a long-standing history of methicillin resistant Staphylococcus aureus (MRSA) osteomyelitis of the ankle and end-stage renal failure (ESRD), receiving hemodialysis. Laboratory workup showed a white count of 28,000 and blood cultures positive for MRSA. The provider determined that the patient’s mental status change was due to sepsis and his final diagnostic statement listed, “sepsis secondary to osteomyelitis.†What is the appropriate sequencing of the principal diagnosis, the localized infection (osteomyelitis) or the systemic infection (sepsis)? How are coders to determine whether the localized infection is the underlying cause of the sepsis? ...

Article Overview
This premium coding article discusses how to approach diagnosis sequencing when a systemic infection occurs in the setting of a localized infection. It is aimed at coding professionals who need to interpret sepsis-related documentation, understand the role of the underlying infection, and apply official guidance in a compliant way.
Why This Topic Matters
Sepsis cases tied to a localized infection can affect principal diagnosis selection and overall claim accuracy. Understanding the coding guidance helps support consistent abstraction of the record and appropriate sequencing in infection-related scenarios.
