ICD-10 Code A41.02 – Sepsis due to Methicillin resistant Staphylococcus aureus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A41.02 – Sepsis due to Methicillin resistant Staphylococcus aureus
What it is
This code identifies sepsis caused by methicillin-resistant Staphylococcus aureus (MRSA). Use it when the documentation links the bloodstream infection or systemic sepsis to MRSA.
Clinical signs
Clinical features vary; refer to documentation. Sepsis typically presents with systemic illness from infection, and the record should support MRSA as the causative organism.
When to use this code
Use A41.02 when the provider documents sepsis due to MRSA, including cases where MRSA is identified as the source of the septic process. You should code it only when the causal relationship is clear in the chart. If the note says MRSA infection without sepsis, choose a different code.
Do not use for
Do not use this code for localized MRSA infections without sepsis, or for sepsis caused by organisms other than MRSA. Check documentation if the organism or sepsis relationship is unclear.
Coding tip
Confirm both sepsis and MRSA are documented together; if the source is stated separately, code the infection and sepsis per documentation.
