is bleach episode 165 filler?

In Szayelaporro Granz's palace, a battered and exhausted 6th Division Lieutenant Renji Abarai gets to his feet, where Dondochakka Birstanne looms toward his face and asks him if he is alright. With Renji startled by this, Dondochakka questions what is wrong, prompting an annoyed Renji to push him back and remind Dondochakka that seeing the latter's face up close makes him feel like his heart is going to stop.

When Dondochakka calls him mean for reacting this way to concern, Renji punches him onto the ground.
