Recreational Diving Medical Screening System

In 2020, the international Diver Medical Screen Committee (DMSC) released a new diver medical screening system and guidance to the physician.

OPPS Final Rule for 2024

UHMS is acutely aware of the radical change in reimbursement that is in the final rule of the 2024 OPPS fee schedule. OPPS refers to hospital outpatient department reimbursement. The physician fee schedule (PFS) addresses physician reimbursement, both in the office setting as well as in the facility setting. G0277 is a unique code since it can be used in all places of service, but the level of reimbursement will vary with location. This has always been the case with the physician fee schedule. 

Because there appears to have been a significant change from the proposed to the final reimbursement schedule, UHMS is conferring with experts in this field to try and determine what happened and what action needs to be taken. We are asking that public comment be delayed until we have more information which we will share with membership as soon as we are able to do so.”


UHMS Accreditation means that your facility has met the highest standards of care and patient safety through our rigorous evaluation of the adequacy of your facility, equipment, staff and training to ensure that the utmost quality is maintained within our specialty.


The Continuing Medical Education mission of UHMS is to develop and promote evidence-based educational activities that improve the scientific knowledge, competence and/or performance within the scope of undersea and hyperbaric medicine, including wound healing.

MEDFAQs is the UHMS Frequently Asked Questions (FAQ) system. This system is a benefit of UHMS membership. Non-members can see the categories of questions we have, plus all questions and answers in the Safety category. Members will be able to see all of the questions, as well submit new questions.
