ICD-10 Coding for MSSA Bacteremia(A41.01, A41.01B, A41.01S)
Learn how to accurately code MSSA bacteremia using ICD-10, including primary and secondary codes, documentation requirements, and common pitfalls.
Complete code families applicable to MSSA Bacteremia
Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| A41.01 | Sepsis due to Methicillin susceptible Staphylococcus aureus | Use when sepsis is confirmed due to MSSA. |
|
| R78.81 | Bacteremia | Use when bacteremia is present without sepsis. |
|
| B95.61 | Methicillin susceptible Staphylococcus aureus as the cause of diseases classified elsewhere | Use as a secondary code to specify MSSA as the causative organism. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.
Key Information
Essential facts and insights aboutMSSA Bacteremia
Alternative codes to consider when ruling out similar conditions
Use when sepsis is due to MRSA, confirmed by susceptibility testing.
Use when MRSA is confirmed as the causative organism.
Documentation & Coding Risks
Avoid these common issues when documenting MSSA Bacteremia.
Omitting organism specificity
Impact
Clinical: Inaccurate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation
Ensure lab results specify MSSA or MRSA, Educate staff on documentation standards
Using B95.61 alone without a primary condition code
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation
Always pair B95.61 with a primary condition code like A41.01 or R78.81.
Not specifying methicillin susceptibility
Impact
Reimbursement: Incorrect DRG assignment affecting reimbursement., Compliance: Potential for audit issues., Data Quality: Misrepresentation of infection type.
Mitigation
Ensure documentation specifies MSSA versus MRSA.
Incorrect sequencing of codes
Impact
Failure to sequence primary and secondary codes correctly.
Mitigation
Educate coders on proper sequencing rules.
