SQL: IF NOT EXISTS

I need to create a one time script for a client to insert data into a column. However, before I do that, I need to check for a condition. My current script is below. How do I modify this script to ADD another condition to also check:

IF NOT EXISTS(SELECT NULL FROM CustomFieldDefinitions cfdef WHERE cfdef.FieldId = 279)

IF NOT EXISTS(SELECT NULL FROM customfielddata cfd WHERE cfd.FieldId = 279)
BEGIN
	INSERT INTO ABC (FieldId, Data, PrimaryId, SecondaryId)
	SELECT 279, 555, E.PartyId, NULL
	FROM Entity E
	WHERE E.EntityTypeId IN (2,3)
END
GO
