Our physical and occupational therapists do their own coding, but I review denials. Most of the information I can find limits the number of units by the total time. They have been billing any services performed for at least 8 minutes. So for example they did 3 different services for 8 minutes each. Under CMS rules that is 24 minutes so we can only bill 2 total units. My providers are billing 3 units unless it is a Medicare/Medicaid/federal plan. When I asked about it, I was given this link: https://newgradphysicaltherapy.com/8-minute-rule-vs-spm-losing-money/
I asked around and none of the coders with therapy experience were familiar with the Substantial Portion Methodology (SPM). I can only find references that come back to this one source/author. It appears to be the way things were calculated before the 8-minute rule came about, but this article is from 2017 and says it can be used with any plan that hasn't adopted the CMS rule from 2000.
Thoughts?
