Update. Had successful procedure in public hospital (Cappagh), woke up in private room. I don't think I had any different medical, physio or catering treatment than anybody else in the hospital. So, over 30 years payments for a private room in a public hospital for 4 nights! Also had to pay for occupational therapy equipment which is free to public patients.
Not criticising surgical, hospital, nursing care - all of that was excellent.
I still have a major problem with paying a substantial annual amount for private health insurance having seen at first hand the excellent medical service provided to all in public hospitals.
The only drawback was that because my health insurance did not cover treatment in private hospitals I had to wait for over 8 months for the procedure. I'm paying a consultant the full whack for all visits pre and post-op and also any xrays required. Luckily, I'm fairly fit and don't need physiotherapy, because I would have had to pay for that because I was under the care of a private consultant.
So, beware of all of the costs involved in any medical procedure, no matter how straightforward it may appear, unless your private health insurance covers you for any event in any medical facility anywhere.
