loop through simple insert statement

I have the following code - the below has to be executed 18 times - the column CPT has 18 occurances in it so rename it each execution and execute - is there a way - starting with CPT1 to execute the below through CPT18
INSERT INTO dbWorking2.dbo.[tblNCD_LAB]
SELECT     replace(ltrim(rtrim(CPT18)),',',''), ltrim(rtrim(ICD9)), effDate, termDate, resCode
FROM         dbo.NCD_Lab_090630
WHERE     (CPT18 IS NOT NULL) and isnumeric(ICD9) = 1
group by CPT18, ICD9, effDate, termDate, resCode order by CPT18, ICD9, effDate, termDate, resCode

This is untested but you get the gist.  

Create a while loop and execute as dynamic SQL:


Declare @iCounter int
Declare @sCounter varchar(2)
Declare @SQL varchar(2000)

Set @iCounter = 1

While @iCounter <=18
BEGIN

Set @sCounter = cast(@iCounter as varchar(2))

Set @SQL = '
INSERT INTO dbWorking2.dbo.[tblNCD_LAB]
SELECT     replace(ltrim(rtrim(CPT18)),'','',''''), ltrim(rtrim(ICD9)), effDate, termDate, resCode
FROM         dbo.NCD_Lab_090630
WHERE     (CPT' + @sCounter + ' IS NOT NULL) and isnumeric(ICD9) = 1
group by CPT' + @sCounter + ', ICD9, effDate, termDate, resCode order by CPT' + @sCounter + ', ICD9, effDate, termDate, resCode
'
EXECUTE sp_executesql @SQL

--print @SQL

Set @iCounter = @iCounter +1

END
