  We study $\N$-graded $\phi$-coordinated modules for a general quantum vertex
algebra $V$ of a certain type in terms of an associative algebra
$\widetilde{A}(V)$ introduced by Y.-Z. Huang. Among the main results, we
establish a bijection between the set of equivalence classes of irreducible
$\N$-graded $\phi$-coordinated $V$-modules and the set of isomorphism classes
of irreducible $\widetilde{A}(V)$-modules. We also show that for a vertex
operator algebra, rationality, regularity, and fusion rules are independent of
the choice of the conformal vector.
