Generally yes. Missouri accepts out-of-state healthcare directives in practice, but doesn't have an explicit reciprocity statute, so recognition rests on hospital practice and emergency-care doctrine.RSMo § 404.703(4) via § 404.805.2 (durability of out-of-state instruments); otherwise general comity — § 404.810 does not incorporate § 404.730Verified Jul 15, 2026 Missouri has no explicit recognition statute for out-of-state healthcare POAs. § 404.703(4) (definitions, applied to the DPOA-HC Act by § 404.805.2) treats a power of attorney as durable if durable under the law of the place where executed or of the principal's residence when executed — statutory support for the durability of out-of-state documents. The general-act reciprocity provision (§ 404.730.5-.6, "durable and may be carried out and enforced in this state") is NOT incorporated by § 404.810. § 404.865 addresses delegation prohibition only. Out-of-state healthcare POAs generally honored under comity if substantially compliant with Missouri law. The document portability tool covers reciprocity rules in detail.
