State Specific Notes


Beginning in 2017, HCUP used the Vermont supplied state indicators for Ambulatory Surgery services: TYPE_AS=1 (revenue code in range of 036x, 037x, or 049x) and SFLAG=1 (surgery flag based on CPT code range 10021-69990).

From 2011-2016, only TYPE_AS was used to define STATE_AS.

For 2006-2010 data, Vermont no longer supplied a state indicator of Ambulatory Surgery services. All records have been assigned missing (.) values.
