Their representatives repeatedly lied to me about submitting preauthorization requests for oxygen equipment. They started by trying to get me to rent equipment while I wait for the insurer to approve the order that they NEVER submitted. Weeks later, they try the same scam, but tell me there was a partial approval of the claim and I should go ahead and rent until final approval. I called my insurer to verify. They NEVER got a submission of the claim. The insurer called Aerocare who verified they never submitted the paperwork. I called Aerocare and told them I will never do business with them again. If you are wise, heed this warning.
