Be prepared to record the same information more than once.
You can't write the word "SAME" to indicate the place where your physician provided services to the patient on your Medicare claims--even if it really is the same as the information you've entered elsewhere.
That's just one of the common mistakes that is causing Medicare to reject your claims, according to MLN Matters article SE0712. Other common mistakes include leaving out the patient's Medicare number, forgetting the referring physician's provider number, billing emergency department codes with an office place of service, or not having enough digits on your diagnosis codes.
