My 65 y.o. husband was diagnosed with CKD 6 months ago with a calculated GFR of 53. We immediately changed his diet to very low sodium, potassium and phospherous, and limited protein. In January (3 Mos. later) his PCP ordered lab work (blood and urine). There was very little change. Here it is 3 more months later, and we want to know if the change in diet is helping. Should he ask his PCP to order lab work again? He is now (recently) on Medicare with a Part G supplemental insurance. Will Medicare cover lab work again? We called medicare, but we are not confident that the information is correct because the representative didn't seem sure and didn't ask for any specifics.
Or should we just wait until November when he is scheduled to see his nephrologist? Any advice would be appreciated.
