(OP)
a post tension slab on grade for a house foundation, you can visually see one of the cables partially. how do you fix this?

If wear and tear will damage the sheathing, then a bonded topping in the vicinity. If not needed for fire rating, then likely just leave it... local stresses may be higher due to greater eccentricity.

If bonded, check the development of the strand. After a certain point, the tendon should regain its full capacity since it is bonded to the concrete. Do you need it for strength or just crack control? Check with VSL. They are good about helping with different type of repairs. Not sure what you would do in your case, but I would think you would need to use some sort of external anchor and a post tensioning rod. You might be able to chip away some of the concrete and embed this in the slab, and "splice" across the damaged areas, but this could be tricky. Again, check with VSL or another PT supplier.
