Yes, you can log into the online platform any time to add on the CUHKMC / GHK wellness package 

Please note that for existing VHIS customers adding any wellness package, Bowtie will apply a 180-day waiting period for the "Full Reimbursement and Cash Benefit for Designated Medical Packages" and a 90-day waiting period for the "Annual Body Check/Optional Health Check Items." Your original VHIS coverage will remain unaffected.

However, if you add the wellness package at the same time as purchasing the Bowtie VHIS Flexi Plan or Bowtie Pink Plan, only the 90-day waiting period for the 'Annual Body Check/Optional Health Check Items' will apply.
