Planning to get medical care abroad - not sure how to plan your budget, flights, and days well

Hello, friend! I'm Enkhjin from Mongolia. I'm thinking about getting some high altitude medical treatment this time, but I'm not sure what my overall budget is. I'm wondering about the flight price, booking a place, how many days off work I should do - how to plan for all of this. Has anyone gone for something like this? Any advice on how to plan or what I'm missing?

I'm thinking about going in the next few months and would like to get some preliminary information. I'm unsure about the flight price, and how many days it will take to recover after the procedure. I'd really like to hear from those who have been there - can you share your experiences? Any advice on budget, time frame, or other practicalities would be appreciated.
