For me, Tymlos is paid for by United Healthcare/AARP my prescription health ins. I have Medicare with Blue Shield, but my IVIG and TYmlos and other prescriptions are again thru AARP ins. This year, there is a cap on prescription meds for us medicare patients at $2,000. Once you reach that cap for the rest of the year, your ins. will pay. Some prescription ins. companies may not cover Tymlos, in which case you would want to switch to one that does. I hope this is helpful. Tymlos is terrific.
