Case statement with multiple conditions

currently I have this query and I have 16 exclusion reasons. Is there a more efficient way to write this beastmode?
CASE WHEN exclusion reason 1
IS NULL THEN
CASE WHEN exclusion reason 2
IS NULL THEN
CASE WHEN exclusion reason 3
IS NULL THEN
CASE WHEN exclusion reason 4
IS NULL THEN
CASE WHEN exclusion reason 5
IS NULL THEN
CASE WHEN exclusion reason 6
IS NULL THEN
CASE WHEN exclusion reason 7
IS NULL THEN
CASE WHEN exclusion reason 8
IS NULL THEN
CASE WHEN exclusion reason 9
IS NULL THEN
CASE WHEN exclusion reason 10
IS NULL THEN
'other' END END END END END END END END END

@renee12345 It looks like you're just trying to find the first exclusion reason that isn't null. You'll want use the COALESCE() function:
COALESCE('exclusion reason 1','exclusion reason 2',…)
COALESCE looks through the first field listed and if it's null, moves on to the next field, and repeats the process until it finds a non-null value.
