Can a psychologist bill to Medicare for a walk and talk session?

Context

I was hoping to please clarify which billing code is appropriate for a generally registered psychologist session using a valid mental health treatment plan lasting more than 50 minutes that is conducted at a regular location that is outside (walking session). Is 80115 the out of office code appropriate to be used for each session? My understanding was that this may constitute an unusual pattern of billing, however the code 80110 mentions specifically ‘in consulting rooms’.
