In Feb 2025 Missouri Baptist Hospital arranged for Lincare to be my oxygen equipment provider. My insurance information was not properly recorded by Lincare, resulting in my being billed the amount that should have been paid by my supplemental to Medicare. Stephanie Doyle is my sales rep and she tells me she has nothing to do with billing. Next I attempted to register with their patient portal to communicate since Stephanie has stopped responding to my emails. The registration process requires you reply with a code they send to my phone. Their system did not send a code after multiple attempts. I want to be reimbursed the amount I paid that should have been paid by my insurance and I want them to stop sending bills even after the insurance information has been corrected.
