A CG-719K form renews both domestic and STCW medicals. Submit the form via email 120 days before expiration. No submission fee.
Yes. A CG-719K will update your medical certificate for domestic and STCW qualifications.

A medical certificate from the Coast Guard certifies that the mariner has the physical capability to fulfill all the requirements of basic training as required by Section A-VI/1 of STCW.
Filling out and submitting the CG-719K form serves as an application for a medical certificate, which is important for your Coast Guard medical certificate renewal. Print out all 10 pages of the form, take it with you to your medical exam so the medical provider can complete and sign the form.
Submit a PDF of your completed CG-719K form (all 10 pages) through Navita, the Coast Guard's new submission portal. Inside Navita you first re-enter your information into an online version of the CG-719K. That version is unofficial, just a paperwork step the Coast Guard now puts in front of the real submission, and Navita will not let you upload your signed, completed form until you finish it.
USCG guidance is that applications should be submitted at least 60 days in advance of the medical certificate expiration date, or 60 days prior to the date the medical certificate will be needed. The team at MM-SEAS recommends you do it 120 days before you need it. It's free and there's no reason not to!
There is no fee to submit the CG-719K form to the Coast Guard for processing your medical certificate. However, you may still need to pay out of pocket for the medical exam itself. This submission also does not affect the cost of your MMC renewal or original application.

We hope this made your life a little easier and if you have other questions the MM-SEAS team is always here to help!

No matter what, when you are ready to submit your application you can do it yourself, or you can hand the whole thing to us. An MM-SEAS Navita Navigator walks you through submitting in Navita, the Coast Guard's new submission portal, on a short video call. No computer, or not up for a video call? Our team gets your application submitted to the Coast Guard for you anyway. A Stress-Free MMC is $399. Two MM-SEAS licensing experts check every page, we pay your Coast Guard fees at submission and charge your card so you never touch pay.gov, and we stay on it with the National Maritime Center until your credential is issued.
MM-SEAS Expert Access is $99 a year. It is your personal guidance counselor for USCG licensing: what training you need next, which sea time counts, and how to reach the credential you want, by phone, email, chat or a 1 on 1 video call. Expert Access members also get $50 off a Stress-Free MMC.
