Is there a code to use for a psychiatrist who plans on doing a group medication education for inpatients - the session would last about 50 minutes and would be for 13-18 patients.

I'm not sure if 90853 would be appropriate - it states for psychotherapy and this is for medication education. I also read somewhere that there is a limit on the amount of patients during these sessions. 90862 doesn't state for groups, so I'm not sure if I could use that code.

If anyone can help me it would be greatly appreciated!
