ASC-13: Normothermia Outcome

On Jan. 1, 2018, data collection began for the Ambulatory Surgical Center Quality Reporting (ASCQR) program’s new normothermia outcomes measure, ASC-13. Data collected from Jan. 1 through Dec. 31, 2018 will be reported in 2019 and may impact the 2020 payment determination.1

Ambulatory Care Normothermia Quality Measure
  • ASC-13: Normothermia Outcome is used to assess the percentage of patients having surgical procedures under general or neuraxial anesthesia of 60 minutes or more in duration who are normothermic within 15 minutes of arrival in the Post Anesthesia Care Unit (PACU).2 Time under anesthesia is defined as the difference, in minutes, between the time associated with the start of anesthesia and the time associated with the end of anesthesia.2

What the normothermia quality measure means for your ambulatory surgery center.

  • Ambulatory surgery centers that do not meet program requirements, which include reporting of quality measure data for the ASCQR Program, may receive a reduction in their ASC payment update. Data for ASC-13 are to be submitted using a web-based tool located on the QualityNet Secure Portal at www.QualityNet.org.

    While payment determination does not begin until 2020, the data collection period is already underway and continues throughout 2018.3 Having protocols in place to maintain normothermia throughout the perioperative process, including monitoring and documenting temperatures, is essential.

Implementation Process

  • The Specifications Manual will become public 6 months prior to when the data collection period is to begin. The January 2018 Specifications Manual will be posted on QualityNet in July 2017.

  • For ASC-13, the data collection period would be the calendar year 2 years prior to the applicable payment determination year. For example, for the calendar year 2020 payment determination, the data collection period would be calendar year 2018. ASCs will submit this data to CMS during the time period of January 1 to May 15 in the year prior to the affected payment determination year. For example, for the calendar year 2020 payment determination, the submission period would be January 1, 2019 to May 15, 2019.
