About XXE5X5A

XXE5X5A is the ICD-10-PCS code for a measurement procedure on the circulatory using an external approach with immune response, whole blood cellular assessment via microfluidic deformability (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 XXE5X4A (infection, positive blood culture small molecule sensor array technology).

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 FY2026, effective October 1, 2025.
