What code is used for a postoperative diagnosis of a catheter-related bloodstream infection (CRBSI)?

The correct code for a postoperative diagnosis of a catheter-related bloodstream infection (CRBSI) is T80.211A. This code specifically represents a complication related to a medical device, such as a central venous catheter, highlighting the relationship between the infection and the catheter.

When coding for complications like CRBSI, specificity is important, and T80.211A indicates that the infection is due to the catheter, signifying it occurred as a consequence of the device rather than due to other factors or in the absence of a device. This distinction is crucial for accurate billing and clinical documentation.

In contrast, the other codes listed represent different scenarios or degrees of complications related to catheters and devices, but they do not specifically address the postoperative nature or the bloodstream infection linked directly to the catheter. Thus, these alternatives would not correctly apply to the specific situation of identifying a CRBSI following a surgical procedure involving a catheter.
