About 4A130B1
4A130B1 is the ICD-10-PCS code for a monitoring procedure on the arterial using an open approach with pressure (qualifier: peripheral). In ICD-10-PCS, monitoring means determining the level of a physiological or physical function repetitively over a period of time.
In plain terms, this corresponds to systemic arterial pressure monitoring, the ICD-9-CM procedure title it maps to (89.61).
For a different body part, codes include 4A140B1 (venous).
The same procedure with a different approach is coded 4A133B1 (percutaneous) and 4A13XB1 (external).
With a different device, use 4A13051 (flow), 4A130H1 (sound), 4A130J1 (pulse) and 4A130R1 (saturation).
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.
