Healthcare in Puglia

We’ve been living in Puglia for 14 months, have our residency and have registered with the health authority. So, we have our Tessera Sanitaria for the next 5 years and a local GP. As my wife has recently had her 60th birthday – receiving a UK state pension - we are now trying to establish how this affects the cost of certain medical services. ( – e.g X-rays, ECG, blood tests, prescriptions, etc).We’ve had a look at the guidelines in the official publications printed by the Italian government and read a number of other articles but (surprise!!) the situation is not that clear. Any information anyone can provide on this topic would be gratefully received.
