To affirm the judgment before us, it is enough to say the government’s arguments for reversal fail to withstand scrutiny. Other questions about the statute’s meaning can await other cases. The dissent would like us to provide more guidance, post, at 13–14, but the briefing before us focused on the issue whether the Medicare Act borrows the APA’s interpretive-rule exception, and we limit our holding accordingly. In doing so, we follow the well-worn path of declining “to issue a sweeping ruling when a narrow one will do.” McWilliams v. Dunn, 582 U. S. ___, ___ (2017) (slip op., at 14).
