When Doctors Opt Out Of Medicare

I opted out of Medicare several years ago. This means I don’t see Medicare patients other than in the emergency room when I’m on unassigned call. I don’t submit bills to Medicare or to those patients. I just let it slide.

Last Wednesday I received the following letter from a large radiology group in my home town:

September 2010

RE:  PECOS Enrollment

To our referring physicians and their office managers:

At __________we have begun a project to identify ordering physicians who are not enrolled in Medicare’s Provider Enrollment, Chain and Ownership System (PECOS).  Our purpose is to remind physicians of the importance of enrollment to them and to us.

Beginning in January, 2011 those providers filing Medicare claims listing an NPI number on the claim of an unenrolled provider will have their claims denied.  This would apply to any claim you send in and to any claim we submit for services provided to your patients because we are required to list your NPI number on our claims.  This applies both to patients referred to our private offices and the hospitals where we provide radiology professional interpretations or services.

So, you can see our effort is not purely altruistic.  We have a financial interest in reminding you of the importance of PECOS enrollment.  In trying to ascertain whether you are enrolled, we are using an online program you can find at  Simply enter your NPI number in the entry block and press enter.  If you enter a valid NPI number, your name will appear and beside it will be a symbol indicating where Medicare recognizes your PECOS enrollment.

Since Medicare is continually updating the files, we may have accessed the system before your enrollment was completed.  We will continue to monitor the situation in hopes you will enroll if you intend to continue seeing Medicare patients.  If you have already enrolled or have no plans to enroll, please excuse our intrusion.


This bothers me. It is not likely that I will be sending them any patients from my office, but that doesn’t mean there won’t be the occasional patient with my name on their chart in the ER. If I need to take a Medicare patient to the operating room from the ER, will the hospital not get paid? Will the anesthesiologist not get paid?

Will my non-participation in Medicare affect my fellow healthcare providers receiving payment? If so, that is just not right. I voiced this concern to Senator Blanche Lincoln shortly after receiving this letter. She agrees with me.

This radiology group is usually correct in their policy interpretations, but I still went searching for more information. I found this summary:  What You Need to Know about Enrolling and Ordering/Referring in the Medicare Program.  It includes this:

Physicians who have validly opted out of Medicare will not need to complete a Medicare enrollment application.

Still, I am not reassured.  The policy doesn’t seem to take into account that I may through unassigned ER call see the occasional Medicare patient. The policy seems to “assume” that since I opted-out, I never see any Medicare patients. If this were the case, I would never affect my fellow physicians/hospitals payment. I’m left wondering if I will affect their payments for that occasional patient I see through the unassigned ER route.

I will tell you that I have gone to the NPI site and reviewed my information. I have gone to the Medicare (PECOS) site and attempted to registered my information. I will not be re-enrolling as a Medicare provider at this point in time.

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
