Yukumoto v. TawaraharaAnnotate this Case
Health insurers do not have a broad, unrestricted right of subrogation against third-party tortfeasors who cause injury to their insureds but, rather, are limited to reimbursement rights established by statute.
In this personal injury case, the circuit court ruled that Haw. Rev. Stat. 663-10 and/or Haw. Rev. Stat. 431:13-103(a)(1) abrogated Hawai’i Medical Service Association’s (HMSA) contractual and common law rights in subrogation against a third-party tortfeasors responsible for injury to its insured. The Supreme Court affirmed, holding (1) a health insurer does not have equitable subrogation rights against a third-party tortfeasor in the context of personal injures; (2) a health insurer’s subrogation and reimbursement rights are limited by section 663-10 and section 431-13:103(a)(1); (3) any contractual provision that conflicts with section 663-10 is invalid; and (4) section 663-10 takes precedence over HMSA’s subrogation rights.
