ANCO member practices (especially group practices) may have received or may receive claims denials with denial code B7 (provider ineligible) due to provider identification (PTAN) number deactivation by the carrier.
The reason for these denials is that your physicians’ PTAN have been deactivated for non-use, OR are not attached to your group identification number, OR your group identification number is not linked to your physicians’ PTANs.
To avoid and resolve these denials you will need to submit Forms 855R and 855I (if the physicians have not updated their Medicare enrollment since 2003). Submit these forms immediately! These forms are available at
CMS 855R Application
CMS 855I Application
Please note that Form 855R does not have a place for reactivation. However, NHIC/Medicare advises providers to write “REACTIVATION” across the open space in section 1 on page 3 of the form.
Submit these forms to the following address using the Option Code Project (in order to expedite processing) cover sheet:
Medicare Provider Certification
P.O. Box 2812
Chico, CA 95927-2812
For additional information, please contact NHIC/Medicare customer service at (877) 527-6613, option 3.
