QUERY TUNE

Hi,

Is their better way formatting this query.
It does a clustered scan instead of seek
SELECT * FROM tablename b WHERE LEFT(b.id, 1) = 'y'
AND CASE WHEN SUBSTRING(b.id, 5, 8) NOT LIKE '%[a-Z]%'
THEN CONVERT(INT, SUBSTRING(b.id, 5, 8))
ELSE NULL END = '13385' OR former_id = 'Z13385'

Please advise
