Abstract: We derive the decay rate of $\pi\mu$ atom formation in $K_{\mu 4}$ decay. Using the obtained expressions we calculate the decay rate of atom formation and point out that considered decay can give a noticeable contribution as a background to the fundamental decay $K^+\to \pi^+\nu\bar{\nu}$.
