How m7b5 Chords Are Used In Jazz

Commonly used as secondary ii Vs to either the I, ii, iii or vi chord.
Also commonly used on the #iv to IV.
When played on the ii, is an inversion of a m6 on the iv. Resolves to 1.

Cool video. Trying to figure out the chords you're playing on That Old Feeling.
I C#M7
iii Fm7b5
vi A#7(b9)
ii D#7(b9)
ii D#m7b5
V G#7(#5,b9)
I C#M7
Is that right?

And yes you can add #5s and b9 s to any of the dominant chords according to your taste.
