Not paying for orthopedic devices in hospital

<p>I had an operation on the 8th of June 2016 where I was supp**** with an arm sling due to an shoulder operation. I recently received my account from the supplier as well as Discovery stating they do not pay for the sling on my in-hospital benefits. I do not agree with this as this was indeed an in-hospital event and not out of hospital. I feel that Discovery is suppose to pay for it.</p>
