Unsp infection due to central venous catheter, init encntr

This code signifies an infection of unknown etiology that is directly associated with the presence of a central venous catheter. It indicates that the infection is not yet specified as bacterial, fungal, or other, but is clearly linked to the catheter as the source.

Use this code when a patient presents with signs and symptoms of a central line-associated bloodstream infection (CLABSI) or local catheter site infection, and the specific pathogen has not yet been identified through culture or other diagnostic testing. This code is appropriate for the initial encounter where the infection is first diagnosed and treatment is initiated.

• Always seek to identify the specific organism causing the infection to allow for more precise coding (e.g., B95-B97 codes).
• Do not use this code if the infection is clearly documented as non-infectious inflammation or mechanical complication.
• Remember the "A" seventh character denotes an initial encounter for active treatment of the condition.
