Query for other recall setups

[cheroxy]

I have a few procedures set up in the recall system which is awesome! I want to do a query where I can see who hasn't had some of these set up, but don't know how to call for this in the query since it is a custom recall? For example, one is a recall for health history updates, a non-ADA code I created to help us get health history updates once a year. I want to query to see who hasn't been put on this recall system, but don't know what that custom created recall code is written as. Any advice

This is the best work around I came up with, but it also shows people that are scheduled for pano recall, but just haven't had it done yet.

/* List of patients with exam but without pano*/
SELECT p.LName, p.FName
FROM patient p
INNER JOIN patient g ON p.guarantor=g.PatNum
INNER JOIN procedurelog pcomp ON pcomp.PatNum=p.PatNum
INNER JOIN procedurecode pccomp ON pccomp.CodeNum=pcomp.CodeNum AND ProcStatus=2
WHERE (
SELECT COUNT(*) FROM procedurelog pl
INNER JOIN procedurecode pc ON pl.CodeNum= pc.CodeNum AND ProcStatus=2
WHERE pl.PatNum=p.PatNum AND
(pc.ProcCode LIKE('D0330'))
AND pl.ToothNum=pcomp.ToothNum
)=0 AND pccomp.ProcCode IN('D0150')
