ICD-10 Code B95.61 – Methicillin susceptible Staphylococcus aureus infection as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B95.61 – Methicillin susceptible Staphylococcus aureus infection as the cause of diseases classified elsewhere
What it is
This code identifies methicillin-susceptible Staphylococcus aureus as the organism causing another documented condition. It is used as an additional code, not as the primary diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record will show S. aureus identified as the infecting organism and the related disease process, such as an abscess, wound infection, or other site-specific infection.
When to use this code
Use B95.61 when the provider documents methicillin-susceptible S. aureus as the cause of a current condition classified elsewhere. Pair it with the code for the underlying infection or disease site. Use it only when the organism is clearly reported in the chart.
Do not use for
Do not use this code for methicillin-resistant Staphylococcus aureus; that requires a different code. Do not assign it when S. aureus is merely suspected, colonizing, or not linked to a documented condition.
Coding tip
Check that the organism and the related diagnosis are both documented before you add B95.61.
