Cardiac rehabilitation for Pacemaker Implantation

I am a 74-year-old woman, and I received a pacemaker 20 days ago. I asked my new cardiology nurse for a referral to cardiac rehabilitation, and she said that unless there was a heart attack, they don't refer to rehab for just a pacemaker implant. I also have a calcium score of 111, so I do have heart disease. I checked with Medicare and they will cover it if it is referred by the cardiologist. Has anyone else faced this? I am so certain that I could benefit both physically and emotionally from that type of support.
