The provider of a service or equipment under sub.

The department shall reduce payments for services or equipment under sub. (11) by the amount of the specified or allowable copayment or coinsurance. A provider may deny care or services or equipment under sub. (11) if the recipient does not pay the specified or allowable copayment or coinsurance. If a provider provides care or services or equipment under sub. (11) to a recipient who is unable to share costs as specified in sub. (11), the recipient is not relieved of liability for those costs.
