Overseas Screening (OSS)
Guam is a remote western Pacific island 7 hours' flying time from Honolulu and 12 hours' flying time from the west coast of the U.S.  Many medical specialty and subspecialty services are unavailable on Guam.  The purpose of Overseas Screening (OSS) is to ensure that the medical, dental, and educational needs of service members and their families can be met with existing resources.  
For additional information concerning the services provided at U.S. Naval Hospital Guam please contact us at: Phone:  (671) 344 9564/7228
CLICK HERE for a detailed list of physical and mental conditions that require an inquiry to be sent directly to Naval Hospital Guam for consideration. 
*UPDATE* - To ensure service members and their families are able to check in with Tricare, please have a copy of the endorsed NAVPERS 1300/16, NAVMED 1300/1, and DD FORM 2807-1 for each dependent. Failure to provide these documents will result in the service member and family to be re-screened at Naval Hospital Guam.  

Per BUMEDINST 1300.2A, the OSS process is required to be completed within 30 days of receipt of PCS orders.  Due to the potential delay in receipt of hard copy orders being received by the service member relatively close to the actual transfer date, it is highly recommended to initiate the OSS process upon receipt of verbal orders to Guam.  It is important that an OSS be completed on each service and family member.  
Service members who marry or acquire dependents after receipt of orders to Guam must ensure that screening of dependents is completed PRIOR TO ARRIVAL on Guam, in order to ensure that dependents' medical needs can be met with available medical resources on the island.  Overseas Screening is required for Command Sponsorship of dependents.  If there are any changes whatsoever in the mental or physical state of those being, or have completed overseas screening, PRIOR TO ARRIVING ON GUAM, require re-screening.  A proper screening helps ensure a productive tour for the service member, his or her family, and the service member's new command.
Suggestions to expedite the screening process:
• Start the OSS process immediately upon receipt of verbal orders.
• Only appointed screeners are able to request OSS for service and family members.
• Provide the DD2807-1 and the 1300-1 and any additional information along with the request for OSS.
• Ensure eligible family members with special needs, whether they be medical, educational, or both, are enrolled in the Exceptional Family Member Program (EFMP)
For further details and to address specific questions about any related OSS issues, please see your area screener.  The screener will be able to go into great detail and answer all questions pertaining to your specific situation.
