confusion re fractionalized "stereotactic brain radiosurgery"

[28 Fracs]

I learned something recently from my doctor. 5 treatments or less is considered radiosurgery by insurance companies and bill at a higher rate than >5 fractions, or radiotherapy. 5 or less fractions is also referred to as hypo-frationization, which has the smallest track record (not to say it is bad). My doctor convinced me to avoid '1-shot' radio-surgery (my hearing still servicable) and use conventional radiotherapy (28 fractions). I completed #20 today; so far so good.

I have a 1.5cm left AN.
