ok, so here is what I know, new codes are effective Jan 1st, all other deleted codes will generate a claim denial. I have been doing a lot of searching and reading and it still is very confusing. There is some information available on the child and adol psychiatry website in the form of tutorials and an algorithm for choosing codes, but The choice of codes appears very difficult and at least UnitedHealthCare has not allowed some codes to be used because of its higher reimbursement. The big question is if you do 45 min of psychotherapy and it involves E/M of medication is this NECESSARILY a prim code with an add on code? but if you use a single code like 90836, then the reimbursement will be lower than last year. It's a real mess. If we can start a discussion, maybe we can figure it out.
