<<Disclaimer: Verify this information before applying it to your situation.>> our HMO is refusing to pay for my husband's Vitamin D (50,000 units a day) and Ferrous Sulfate...has anyone else encountered this type of problem? He is newly diagnosed; should I send the HMO copies of his bloodwork to show how low his levels are?? Would they rather pay for his fractures and transfusions...I guess they would.
