I am facing strange problem when running a below query with comment as RED COLOUR its coming fine

Can you come again on this?

Try nvl instead of is null
/*AND (C.TROD_VALID_TO IS NULL OR C.TROD_VALID_TO >= To_date('06/04/2009 12:00:00','dd/mm/yyyy hh24:mi:ss'))*/
to
/*AND nvl(C.TROD_VALID_TO,To_date('06/04/2009 12:00:00','dd/mm/yyyy hh24:mi:ss')) >= To_date('06/04/2009 12:00:00','dd/mm/yyyy hh24:mi:ss')*/

Please try with these clause:
---------------------------------
Approach1:[Logic of from and to changed]
--------------
AND nvl(C.TROD_VALID_TO,To_date('09/04/2009 12:00:00','dd/mm/yyyy hh24:mi:ss')) <= To_date('09/04/2009 12:00:00','dd/mm/yyyy hh24:mi:ss')

AND c.trod_valid_from >=
TO_DATE ('06/04/2009 12:00:00', 'dd/mm/yyyy hh24:mi:ss')
---------------------------------------------
If the above does not work:
Approach2:
----------
1.create a view with the commented query.
2.Then introduce the commented clause to select from the resultset of that view.
I think once we see the outcome;we will get a hint for hanging.

Another query : what is MAXCARE in the plan?

I am not able to understand the plan:It is not showing any index names etc. although it is claiming index scan?

Thanks Gurinder.
One more query:
-------------------
The execution plan which you have enclosed,is it from explain plan or is it the actual execution plan?(i.e. from sql trace or from v$sql_plan). some part of your predicate seems to be missing there.
Please provide the other plan also.Stating which one is what for farther analysis.

Gurinder another approach to make things simpler and analyze the problem:
Can you comment out the query from AND EXISTS (
SELECT 1
FROM encounter

till end. Then test it to see whether the query is still hanging.
