(5)__A health benefit plan may not impose a limitation on coverage or benefits for mental illness unless that same limitation is also imposed on the coverage and benefits for physical illness covered under the policy or contract.

(6)__Copayments required under a policy or contract for benefits and coverage for mental illness must be actuarially equivalent to any coinsurance requirements or, if there are no coinsurance requirements, may not be greater than any copayment or coinsurance required under the policy or contract for a benefit or coverage for a physical illness.
