April Sue,
It is hard and frustrating some days to be a good coder in an evolving coding landscape. If it makes you feel any better, one of the most recognizable voices in dermatology coding used to tell us, as recently as 3 years ago, that it didn't matter if you picked 238.2 or 239.2 for biopsy coding... I'm not saying I agree with her, but that came from a respected person in the coding world. Sometimes coding is like religion. Everyone adamantly believes s/he is right.
Here's how I approach it:
I accept that I am probably wrong about some of the things I do. Unknowingly so, but still wrong. I may need to change my approach to a certain topic when new information comes to light.
I seek out new information. A lot. From different sources. I do not accept someone's opinion at face value, but look to find resources that support it. In the absence of official resources, I accept that a well reasoned internal policy may be all that I can do.
I get very cozy with my ICD-9 and CPT books. Very cozy. Little bits of information are tucked into each section that sometimes get overlooked. (Like the histo-morph passage at the beginning of the Neoplasms of Uncertain Behavior section and the list of "Includes" at the beginning of Neoplasms of Unspecified Behavior.)
In communicating with my providers, I make it clear when I'm in a gray area and that as things evolve, we may need to evolve too. It's a process to build trust with your providers. Ask them questions, find out what's going on in their exam rooms, and then compare with their documentation. Start with the easy stuff, like documenting all the bullet points or body areas. It's a wonderful way to build your relationships with your providers, and then it allows you to have real and meaningful discussions with them about the stuff that's less clear.
Before I walk into a meeting with my provider, I make sure I'm not riding my high horse. It's obnoxious, counter-productive, and when I find out I'm wrong about something and have to change things, it makes it very difficult to be an effective change agent. I am very good at my job, but I am imperfect at it. I make sure my providers see that aspect so they can understand where we might have weaknesses. It's a partnership, and my partnerships don't work well when I'm always the "most right person" in the room.
Finally, I breathe. I move forward using the best information I could come up with and again, accept that I'm probably wrong about something today. Coding and compliance are risk-based and risk-mitigating activities. I'm comfortable with that and strive to mitigate risk whenever possible.
You'll get there. The first couple of years of coding are the hardest, but it gets easier. Stay in touch with other coders, be honest with your providers about your misinterpretations or misunderstandings, and keep moving forward.
I sat through an 8 hour meeting with my docs this week. The topics were mostly coding, compliance, PQRS, Meaningful Use, etc. At the end of the day, my senior partner came over and hugged me. "I am sooo appreciative that we have you," he told me. That hug and comment was the culmination of years of work between the two of us. It didn't happen overnight, but then it wouldn't have meant so much if it had.
Good luck, we're all in your corner
