Okay, this is one of my favorite topics (not!). Even if not, it is one of the most important things for you to understand.
The VASRD simply cannot include every single possible medical condition in the world. There are just too darn many. Because of this, the VASRD includes the Analogous Principle that allows conditions that are not included in the VASRD to be rated on the rating system of the closest possible condition that is rated by the VASRD.
What exactly does this mean? Whatever condition you have that is not in the VASRD, find the next closest condition and rate it there. The best rule of thumb is to use the condition that shows most if not all of the main symptoms of your condition. So, if you have a condition that is not in the VASRD, and your main symptom is high blood pressure, then just rate it under the code for high blood pressure (code 7101).
It can sometimes get a bit confusing trying to figure out where a condition should be rated. You may have to search a bit, but just remember: find the condition that has the majority of the same symptoms as your condition.
If your condition is pretty complicated, and you really just can’t figure out how to rate it, feel free to Contact Us, and we’ll be more than happy to help you the best we can.
