SUBMISSION OF MED CERT APPLICATIONS TO NMC
To continuously improve our services to mariners, the Coast Guard has established a new
option for submission of medical certificate applications (CG-719K and CG-719KE). Beginning
February 1, 2018, mariners may submit medical certificate only applications directly to the
NMC. RECs will continue to accept medical certification application submissions as well.
Applications for an MMC (CG-719B) cannot be submitted directly to the NMC. Any
application for a medical certificate that is submitted with a CG-719B (MMC and
medical certificate) must be submitted to an REC.
Medical certificate applications can be submitted to the NMC via e-mail at:
MEDAIP@uscg.mil.
