CMS has published the final MAC Gapfill rates for CY2021, finalizing the MAC gapfill rates initially proposed in May 2021.
Find the rates on this webpage:
Scroll down to the header, GAPFILLING DETERMINATIONS, and see the file, "2021 CLFS Gapfill Final Determinations." (I had to reload my screen a couple times for this to appear.)
To read about today's proposed CLFS prices for NEW codes, to be used in 2022, see here.
There were 53 codes in the gapfill process. By reference to tab 2, "Rationales," 20 of the 53 codes received pricing comments over the summer, because they have some kind of rationale remark in response.
- Four codes were revised at enough MACs to change the median rate calculation (0156U, 0165U, 0178U, 0219U).
- That's it.
- All the other codes were not revised, suggesting that gapfill prices are pretty "locked in" when first published in May.
- Most codes had no changes anywhere, despite CMS having logged comments.
- One code had changes "at some MACs" but not enough to change the median.
Meaningful changes = 4/20 commented = 20%.
Meaningful changes = 4/53 codes under gapfill = 8%.
