Medical Insurance 80D

In case of Deduction under section 80D i have one doubt. In a case where the husband and wife was filing ITR seperately, they have taken a familiy medical insurance policy of Rs. 50 Lakh (Annual Premium Rs. 50000). At the time of filing ITR, each one claim Rs. 25000 as deduction under section 80D. Whether the procedure was correct or whether seperate insurance policy should be taken individually?
