I am looking for a reasonable short explanations of what the conjunctive words mean in CPT coding

IE, CHF and ESRD with hypertension.

I’m trying to ascertain the direction of the words "and", "but" "with", "due to" and any other verbal linkages. I am sitting for the second time for my CPC in 2 months and I feel my ignorance of these terms may have contributed to my poor score. I understand they are directional for sequencing, but I can not seem to find a simple list and explanation for any and all conjunctive words for CPT. I code ICD10 all day long but very little of my job deals with the CPT codes or books.

Thanks in Advance.
