is bleach episode 276 filler?

Baraggan, Suì-Fēng, and Ōmaeda are watching the Respira's effect on Suì-Fēng's severed left arm. When the flesh and bone disintegrate into nothing, Baraggan remarks sarcastically that it's amusing to find that Shinigami are afraid of death. Ōmaeda leans close to Suì-Fēng to ask her if she's alright, but she backs away, ordering him to stay away because he makes her sick. Ōmaeda ponders that while he's seen his share of opponents, Baraggan is by far the most dangerous, even more so than Sousuke Aizen.
