Mediclaim under Section 80 D

I have bought insurance cover for my senior citizen parents above 70 years under group health plan from my firm on co payment basis for 2020-2021. Unfortunately, I had to seek expense reimbursement as my mother went hospitalization. As per T&C of plan I was eligible for reimbursement of only 85% of expenses. Can I claim non-reimbursed amount from my tax liability for FY - 2020-21
