Abstract: We consider planar homeomorphisms $ f\colon\mathbb{R}^2\to\mathbb{R}^2$ that are of finite distortion and map the unit disk onto a specific cusp domain $ \Omega_s$. We study the relation between the degree $ s$ of the cusp and the integrability of the distortion function $ K_f$ by sharpening a previous result where $ K_f$ is assumed to be locally exponentially integrable.
