Maintaining Undersea and Hyperbaric Medicine Certification

Emergency Medicine physicians certified in Undersea and Hyperbaric Medicine must participate in an ABEM-accepted continuing certification process and pass the UHM MOC Examination every ten years to maintain certification. ABEM believes that physicians who continue to practice Emergency Medicine in addition to their subspecialty should continue to maintain their EM certification.

Exam Process

The Undersea and Hyperbaric Medicine MOC Examination is offered on multiple dates throughout the year.


The Undersea and Hyperbaric Medicine MOC Exam is open to UHM-certified physicians in years six through ten of their certification cycle.


To register for the Undersea and Hyperbaric Medicine MOC Examination, UHM-certified physicians complete the current year’s registration form, which is available from the ABEM office.

The following must be submitted for an application to be complete:

  • Completed and signed current-year registration form
  • Additional items included in the materials or referred to in the registration form instructions, if applicable
  • Registration fee and examination fee in U.S. funds

The registration fee is an administrative fee that covers the cost of reviewing and authorizing the examination registration and submitting that authorization to the board that administers the exam, and cannot be refunded.

By signing the application form, physicians give ABEM permission to verify information submitted.

ABEM emails a receipt when the registration and examination fees are received and a notification when the examination authorization has been sent to the administering board. 


Physicians will receive information about how to schedule an appointment to take the exam.

Taking the Exam

The Undersea and Hyperbaric Medicine MOC Exam is a two-hour, pencil-and-paper exam, consisting of 100 multiple choice questions administered at various locations in the U.S.

All candidates achieving a final score of 60 or higher will pass the examination.

Content Specifications

The exam outline for the Undersea and Hyperbaric Medicine MOC Examination is available on the ABFM website.


ABEM sends candidates the results of their examination in writing. Results are also posted online.

To regain status, they must make up missed requirements before the end of their ten-year certification period.
