About 6A651ZZ

6A651ZZ is the ICD-10-PCS code for a phototherapy procedure on the circulatory using a multiple approach with no qualifier. In ICD-10-PCS, phototherapy means extracorporeal treatment by light rays.

In plain terms, this corresponds to therapeutic photopheresis, the ICD-9-CM procedure title it maps to (99.88).

For a different body part, codes include 6A601ZZ (skin).

The same procedure with a different approach is coded 6A650ZZ (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.
