I got extremely lucky with top surgery; it was covered by my insurance so all I had to pay was a tiny copay, along with money for supplies, medication, post-surgical binder, etc. All in all, it came to less than 100$ I think.
But yes, depending on where you live and what your insurance is you might have trans related healthcare that's covered. You can contact and ask about your coverage and copay/deductible, and if they don't cover it outright you also still have the option to make your case and try to get it covered. Best of luck!
