Complete code families applicable to MRSA
Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| B95.62 | Methicillin-resistant Staphylococcus aureus as the cause of diseases classified elsewhere | Use when MRSA is identified as the causative agent of an infection classified elsewhere. |
|
| A41.02 | Sepsis due to Methicillin-resistant Staphylococcus aureus | Use when sepsis is confirmed to be due to MRSA. |
|
| J15.212 | Pneumonia due to Methicillin-resistant Staphylococcus aureus | Use when pneumonia is confirmed to be due to MRSA. |

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 aboutMRSA
Alternative codes to consider when ruling out similar conditions
Use when the infection is due to methicillin-susceptible Staphylococcus aureus.
Use when the causative organism is not specified.
Use when the bacterial cause is not specified.
Documentation & Coding Risks
Avoid these common issues when documenting MRSA.
Omitting the infection site code
Impact
Clinical: Incomplete clinical picture, Regulatory: Non-compliance with coding guidelines, Financial: Potential claim denials
Mitigation
Always document and code the infection site first, Review coding guidelines regularly
Using B95.62 as the principal diagnosis
Impact
Reimbursement: Claims may be denied if B95.62 is used as the principal diagnosis., Compliance: Non-compliance with ICD-10 sequencing rules., Data Quality: Inaccurate representation of the patient's condition.
Mitigation
Always sequence the infection site code before B95.62.
Using Z16.11 with MRSA codes
Impact
Reimbursement: May lead to claim rejections due to redundancy., Compliance: Violates ICD-10 coding guidelines., Data Quality: Redundant coding affecting data accuracy.
Mitigation
Do not use Z16.11 with MRSA codes as resistance is inherent.
Incorrect sequencing of MRSA codes
Impact
Using B95.62 as the principal diagnosis can trigger audits.
Mitigation
Educate staff on proper sequencing rules.
