What This Code Means

B95.61 is the ICD-10-CM diagnosis code for methicillin susceptible staphylococcus aureus infection as the cause of diseases classified elsewhere. Methicillin-susceptible Staphylococcus aureus (MSSA) bacteria identified as the cause of another disease or infection in the patient. B95.61 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering bacterial and viral infectious agents (b95-b97).

B95.61 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models.
