Question juridique clé
Whether the insured owed the claimed unpaid cost-sharing, premiums, administrative fees, and default interest so that definitive legal opening could be granted.
Solution extraite
Yes. The claimed amounts were sufficiently substantiated and the insurer’s decision constituted a valid basis for definitive legal opening.
Motifs extraits
The court found the cost-sharing and premium arrears undisputed as to amount. The set-off argument based on alleged counterclaims for hospital costs was irrelevant in this proceeding and, in any event, no right of set-off existed for either party in the context of outstanding premiums or cost-sharing.
