I claim the ornamental design for a display screen or portion thereof with complex case and disease management graphical user interface, as shown and described.
FIG. 1 is a view of a display screen or portion thereof with complex case and disease management graphical user interface of my new design;
FIG. 2A is a partial view of a display screen or portion thereof with complex case and disease management graphical user interface of my new design, the partial view of FIG. 2A showing an upper part of the design;
FIG. 2B is a partial view of the display screen or portion thereof with complex case and disease management graphical user interface of my new design, the partial view of FIG. 2B showing a middle part of the design that borders the partial view of FIG. 2A at the bottom of the partial view of FIG. 2A;
FIG. 2C is a partial view of the display screen or portion thereof with complex case and disease management graphical user interface of my new design, the partial view of FIG. 2C showing a middle part of the design that borders the partial view of FIG. 2B at the bottom of the partial view of FIG. 2B; and,
FIG. 2D is a partial view of the display screen or portion thereof with complex case and disease management graphical user interface of my new design, the partial view of FIG. 2D showing a lower part of the design that borders the partial view of FIG. 2C at the bottom of the partial view of FIG. 2C.
The broken line made up of single-length dashes, showing a display screen in each view, forms no part of the claimed design. The broken lines made up of alternating long and short dashes, showing borders between the partial views, forms no part of the claimed design.
