I want to do a snip will discovery cover this? or do i have to use my medical aid savings to cover it?

By a "snip" are you: referring to a vasectomy?? If so I am not familiar with your health insurance situation so cannot answer. Ask the practioner who you want to do the procedure.

Contact plan.: There are many different insurance companies and most have many plan types. We cannot possibly know all the different plan benefits. You need to contact your plan directly and ask if this is a covered benefit, and which doctors are covered by them to do the procedure. Your current GP may know more and is a good person to ask for a referral to a doctor he/she knows well and trusts.
