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 does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This is a secondary code used with the primary diagnosis code for the MSSA infection.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B95.61 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a secondary code used with the primary diagnosis code for the MSSA infection
- •MSSA is susceptible to methicillin and related antibiotics, distinguishing it from MRSA
