This is a number used to identify a PATIENT uniquely within a HEALTH CARE PROVIDER. It may be different from the PATIENT's casenote number and may be assigned automatically by the computer system.
Where care for NHS patients is sub-commissioned in the independent sector or overseas, the NHS commissioner PAS Number should be used. If no NHS PAS Number has been assigned the independent sector or overseas PAS Number should be used.
