Hi! So happy to hear from someone in the same boat!
I took it in July and failed with 63%! I found the E&M's really hard too, and modifiers, and closures. I used to code outpatient Derm and did E&M's, Mohs, biopsies, path, the works, but that was a few years ago. Despite the AAPC class, and buying the practice test, I still failed. Very frustrating. I'm retaking the test this Friday. This time around I did buy the AAPC study guide, and I am finding it helpful, especially the Top 10 Missed Coding Concepts (I tried to make a copy/screenshot but it wouldn't let me, sorry!). I think it's $45 for members, not sure if it's worth if for you. There is a practice test included with it that I haven't gotten to yet.
As for HCPCS codes, I don't know what was on your test, but both on the practice test and my exam, there are only 2 that I think think you really need and those are
J3301 - Kenalog (

The other is J7308 (
https://www.hcpcsdata.com/Codes/J/J7308) to code with 96567 (Photodynamic therapy). If you had any others on your exam, please give me a heads-up before Friday!!
I also found this, that I haven't watched yet so I have no idea if it's worthwhile or not!
But any little bit's gotta help, right?
