Welcome to Flyertalk and welcome to the BA forum.
There is generally a 1 year rule on ticketing. You can within that 1 year get the ticket reissued with a voluntary change, then the validity is 1 year from that reissued date. But you can't push it to say 13 months or more. There isn't a lot of point in buying tickets way off, it's rarely a cheap or flexible way to travel. If you are medically unable to travel you may be covered by travel insurance perhaps.
