Income tax - medical insurance by employer

Dear experts,

A company is paying Group Mediclaim Insurance for 1 year with GST and it will be recovered by employees salary, due to recovering the medical insurance from salary can be the employee avail 80D benefits?

Can we recover Insurance amount with GST from the employee or we only recover insurance amount?

If we recovering the insurance amount with GST form the employee's salary, shall we still allow to claim the Input tax credit by the company?

Please advice.
