My wife had an ablation a year and a half ago. Her lower left chamber was okay. The upper right was all scar tissue so five hours of surgery could only accomplish so much. (She never smoked)
She just had a pacemaker put in this past April. She had a lot of complications with swelling, oozing, etc. but it calmed down and is working (constantly).
She went on Medicare before I did. The agent that we worked with for her supplement recommended the "F" plan and I followed suit. If we get a bill, the "radar" goes up. It happens on occasion but a phone call usually clears it up.
But we had one that billed us about one year after my wife had a procedure. They claimed that we had not provided our secondaries info. Lie! They said that we had not signed me as okay to converse with. Lie! I forwarded two hipa forms which they claimed to have never received. I called my secondary. Turned out that they sent improper paperwork three times to our secondary. The last time that they called, after they told me that they needed to speak to my wife and could not speak to me, I told them to see us in court. (My wife is hearing impaired so I do all of the phone work.) I then sent Medicare all of the info. Not sure if that worked but we never heard from them again.
I would have to look at our statements to see what her TAVR, ablation and Pacemaker costs were. If I recall correctly, my knee joint alone was around 50k just for the joint.
By the way, I go over all of our Medicare statements looking for false claims. I have called Medicare for at least three Covid test kits that we never asked for or received.
