Methicillin resis staph infection, unsp site

This code signifies a bacterial infection caused by Methicillin-resistant Staphylococcus aureus (MRSA) where the specific anatomical location of the infection is not documented. It indicates the presence of a resistant strain of Staphylococcus aureus without specifying if it's a skin infection, pneumonia, bloodstream infection, etc.

Apply this code when documentation confirms a MRSA infection but lacks specificity regarding the site of infection. This is often seen in initial lab reports confirming MRSA without further clinical detail or when the provider simply states "MRSA infection" without elaborating on the affected body system.

• Always attempt to query for a more specific site of infection to allow for a more precise code assignment.
• Do not use this code if the documentation specifies the site of MRSA infection (e.g., MRSA pneumonia, MRSA cellulitis); instead, use the appropriate site-specific MRSA infection code.
• This code is often a secondary diagnosis, with the primary diagnosis reflecting the patient's main reason for the encounter.
