Depleting Savings Account for Chronic Benefits

Mum's savings being depleted for chronic blood tests. This problem is recurring for years now with no permanent resolution from Momentum. Lancet submit the correct ICD codes that Momentum systems cannot automatically "read" and as such claims are processed from savings. My mum is 79 years old now and each year i need to come to this platform for resolution. How many other heart patients are you cheating with inefficient systems? I am now looking to lodge an official claim with the Ombudsman in this regard or go to the media with this.
