About XXE5X4A

XXE5X4A is the ICD-10-PCS code for a measurement procedure on the circulatory using an external approach with infection, positive blood culture small molecule sensor array technology (qualifier: new technology group 10). In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.

With a different device, use XXE5X2A (infection, phenotypic fully automated rapid susceptibility technology with controlled inoculum) and XXE5X5A (immune response, whole blood cellular assessment via microfluidic deformability).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2025, effective October 1, 2024.
