About 4B09XSZ

4B09XSZ is the ICD-10-PCS code for a measurement procedure on the respiratory using an external approach with pacemaker. In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.

In plain terms, this corresponds to other nonoperative respiratory measurements, the ICD-9-CM procedure title it maps to (89.38).

For a different body part, codes include 4B02XSZ (cardiac).

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

It has been valid since ICD-10-PCS took effect on October 1, 2015.
