thanks Lamar, this worked
SELECT ToxPat.CaseNumber, ToxPat.StartDate, ToxExpSub.SubDesc 

      , ToxExpSub.SubPoisindexCode, CodeValue.CodeValue as 'Call Type' 
from ToxExpSub 

join Toxpat 
     on ToxPat.CaseNumber = ToxExpSub.CaseNumber 
join CodeValue 
     on codevalue.CodeID = toxpat.calltype 
where exists ( 
     select 1 from ToxExpSub x 
     where x.SubPoisindexCode = 6931087 
       and x.CaseNumber = ToxPat.CaseNumber 
) 

NOW can I issue multiple JOIN like this join CodeValue 
     on codevalue.CodeID = toxpat.calltype .  reason being is Codevalue table has the definitions for many fields numeric entries
For example, I will also like to use:
Join Codevalue on Codevalue.CodeID = toxpat.ReasonCall

is it possible to issue multiple Join codevalue on codevalue.codeId = toxpat.Column1, column2, etc
