also, is this a "regular" heap table?
or maybe a view with a hidden ROWNUM predicate? or an external table, or a global temporary table?

kind regards,

The first thing that leaps to mind to try to identify the problem is to use NVL() on both columns in your select to display something (the string 'this is NULL' for example) if the value is null, or maybe do a select count(*) from image_staging_table; to check there's only one row.

It's possible that your table might have two rows looking like:

HOSPITAL_ID      ACCT#
-----------------      -------------
ASHFORD               [NULL]
[NULL]                     X104978978

rather than one row such as:

HOSPITAL_ID      ACCT#
-----------------      -------------
ASHFORD                X104978978

which is what you are presumably expecting.
