Selecting from colection within a table

I'm trying to see if I can use collections within tables instead of long where conditions with lots of ORs but I'm stumbling right now.
I have an existing table similar to below along with code used to select rows from the table:
diag_i_1 VARCHAR2(10), diag_i_2 VARCHAR2(10), diag_i_3 VARCHAR2(10),
WHERE diag_i_1 IN ( 'A','B','C','D','E' ) OR diag_i_2 IN ( 'A','B','C','D','E' ) OR diag_i_3 IN ( 'A','B','C','D','E' );
Using a collection within the table like below, I want to emulate selecting from the table when the column could contain a list of values like above.
diagnosis_code t_diagnosis_code_va11, );
CREATE OR REPLACE TYPE t_diagnosis_code_va11 AS VARRAY(11) OF VARCHAR2(10);
INSERT INTO TEST VALUES ( t_diagnosis_code('A','B','C') ); INSERT INTO TEST VALUES ( t_diagnosis_code('A') );
FROM test a
WHERE 'A' IN ( SELECT * FROM TABLE(a.diagnosis_code) );
returns two rows.
HOW would I emulate selecting rows where the diagnosis_code could be a list
of values such as 'A' or 'B'
like the IN statements in the original code?
When I try:
FROM test a
WHERE ('A','B') IN ( SELECT * FROM TABLE(a.diagnosis_code) );
I get: ORA-00947: not enough values
Any help would be appreciated.
