About 6A751Z4
6A751Z4 is the ICD-10-PCS code for a ultrasound therapy procedure on the circulatory using a multiple approach with no qualifier (qualifier: head and neck vessels). In ICD-10-PCS, ultrasound therapy means extracorporeal treatment by ultrasound.
In plain terms, this corresponds to therapeutic ultrasound of vessels of head and neck, the ICD-9-CM procedure title it maps to (00.01).
The same procedure with a different approach is coded 6A750Z4 (single).
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.
