Practice, practice, practice - that is how you get better and more efficient at anything. I know what you mean though - you see all these paragraphs of information and it can be overwhelming. For op reports start with the the procedure title and start to look that up in the index. Then when you go to the codes it directs you to figure out what the difference is between the codes and read the report to see which one best fits your documentation. Then read through it to see if there are any ancillary procedures you can bill for that were not explicitly mentioned in the procedure title. That's where a lot of money is left on the table.
If you're not sure if a procedure is included (bundled) into your main procedure pop it into and encoder to check CCI edits. I like using
Findacode
Here's a video I did recently on checking CCI edits
