Lab coders, did you notice the new symbol on TCI SuperCoder’s code pages? The CPT® 2018 code set added a new symbol for duplicate proprietary laboratory analyses (PLA) codes, so we’ve added it on our code details and code listing (range) pages, too.
The gist: The descriptors for some PLA codes are the exact same, with your choice between them being based on the proprietary name of the test you used. The symbol lets you know the code you’re looking at is one of those codes. In the image, you can see the symbol in the red box. Check the code details page for information on which codes have duplicate descriptors, and which proprietary name applies to the code.
