Do I need to renew my USCG medical if I have a few months left?

If you Medical is still valid, you can get away with renewing your MMC without renewing your Medical at the same time.



That being said, your MMC is invalid the second your medical is not valid. For mariners who only hold domestic (National) endorsements they need to renew their medical every 5 years to keep their MMC valid. If you also hold STCW endorsements, then you need to keep your STCW medical up to date as well. If your hold any STCW endorsement and your STCW medical is expired, Your entire MMC in invalid and you cannot work on it.

If a mariners MMC or corresponding medical is not current the entire MMC in invalid and the mariner is not allow to work on their license until their medical and MMC are not expired.
