Sometimes Medicare patients are admitted in observation status instead of on an inpatient basis. This can affect the amount of the patient’s bill. It may not be clear how a patient has been admitted until they receive a bill. If you are in that situation, there are some materials here that might be of use to you: http://www.medicareadvocacy.org/self-help-packet-for-medicare-observation-status/.
Like all my posts, this is not legal advice, and I am not your attorney just because you are reading the blog. If you have any questions, contact an attorney, stat!
