DATE OF DEATH

WHAT ARE THE STEPS IN CORRECTING A DISCREPANCY IN A PERSONS DATE OF DEATH? EXAMPLE HOSPITAL MEDICAL RECORDS HAS ONE DATE AND MEDICARE AND SOCIAL SECURITY OFFICE HAS ANOTHER DATE. COULD BY A POSSIBLE TYPO ERROR. PER DEATH CERTIFICATE THE HOSPITALS DATE OF DEATH IS CORRECT. HOW CAN THE DATES BE RECTIFIED TO THE CORRECT DATE OF DEATH?
THANK YOU
