Hi Stormgirl - as outlined in my previous post, yes PHI pay for the theatre fees for the the EPU and ET procedures. You can find out which day hospital is used for these, and ring & ask the costs.
PHI will also pay a small amount for anaesthetist - but they don't really pay all that much for that. It's the theatre fees that are the biggest expense. Everything else for IVF has nothing to do with PHI and will not be covered.
