Lots of things look strange about this: no spaces between some operators (*FROM; HAVINGCOUNT; pat_matchesINNERJOIN; RENDERING_PROVIDER_KEYWHERE)
Something is missing here: main_table_name mtn but I can't tell what because both mtn and main_table_name look like tables, not one a field and the other a table
You seem to be treating CPT_HCPS_PROC_CD as text in one place ('82330' and numeric in another = 8)
Lastly, in my limited experience with sub queries (which is what you have) the sub query table and field references have to be aliased, which I don't see here.
Your error might be due to 8 being text and you have no quotes around it. If so, I think you will move on to other errors based on the above.
The more we hear silence, the more we begin to think about our value in this universe.
