is bleach episode 183 filler?

At the Second Division barracks, Lieutenant Marechiyo Ōmaeda orders his search team to stand by and wait, since there is three other squads who have sent out search units looking for Ichigo Kurosaki, Rukia Kuchiki, and Shū Kannogi. Meanwhile, Izuru receives a Hell Butterfly which relays Captain Shūsuke Amagai's message about teaming up with Ichigo; while Ichigo, Amagai, Rukia, and Kannogi converse, they are seen by two Seventh Division Shinigami who decide they need to report this development to Captain Sajin Komamura.

Amagai reveals that he is helping Ichigo because of Makoto, who seems to have some sort of affiliation to the Kasumiōji Clan.
