Stop using functional reporting codes such as G8539

The Functional Reporting requirements for pain and functional scales (G8539, G8730 by example) to Medicare are no longer required. In fact use of the codes will result in the claim being denied effective for dates of service on and after January 1, 2019.

Beginning in 2021 any use will cause the claim to be denied though they were not needed after 2019 they would not cause a denial if used. Now any use will cause the claim to reject as invalid.
