Guidance for 2 OASIS-E items has already changed. The new OASIS-E tool and its guidance is far from set in stone, and home health agencies should stay tuned for forthcoming instructions. There are “so many outstanding questions,” relates Arlynn Hansell with SimiTree Healthcare Consulting. “The help desk is very busy, and will only get busier as folks start reading the guidance manual,” Hansell expects. Providers have already been asking the Centers for Medicare & Medicaid Services questions about OASIS-E, and guidance has changed before the tool even takes effect, highlights Cindy Krafft with Kornetti & Krafft Health Care Solutions. Recap: In its July OASIS quarterly questions-and-answers, CMS updated instructions for D0150 — Patient Mood Interview (PHQ-2 to 9) and D0160 — Total Severity Score, noting that “this guidance supersedes instruction provided in the draft OASIS-E Guidance Manual, posted May 2022. Use this more recent guidance when implementing OASIS-E in January 2023” (see HCW by AAPC, Vol. XXXI, No. 26). “We will have to watch the Q&As for the remainder of the year to make sure we have the most current information when we go live,” Krafft concludes. The Q&As are at https://qtso.cms.gov/reference-and-manuals/oasis-quarterly-q. “There are going to be some outstanding questions, particularly as the instrument moves into use,” predicts Angela Huff with FORVIS. After the July Q&A clarification, “I expect more to come. There always are questions that surface once the tool is in use,” Huff tells AAPC. “No OASIS tool is ever final,” points out Beth Noyce with Noyce Consulting. “The fact that we have so many versions behind us shows that CMS is always studying and revising the OASIS to try to improve it.”
