For persons covered by a single service plan (SINGLEE), SSACCID reports whether the person was covered for accidents. Respondents were asked what type of single service plan the person had and handed a list with different types of single service insurance coverage. Interviewers instructed them to mark all that applied.

For 2004 forward, the survey included an additional probe question for all persons who indicated they were not covered by health insurance or did not indicate single service plan coverage. A person who responded to either HISINGLE or SSPROB, single service plan probe response, were asked about the type of service.

For variables indicating other types of single service variables, please see the SINGLEE variable description.


SSACCID is mostly comparable, however the percent of respondents indicating single service coverage may increase for 2004 as a result of a probe question on whether the person had any single service plan.

SSACCID is not comparable with variables from before 1997, such as responses in HI1TYPE, as responses for SSACCID reflecting editing by the National Center for Health Statistics (NCHS) based on plan name to ensure accuracy in insurance type. For example, there may be a mismatch between the plan name and the actual type of plan. From 1997 forward, the NCHS reassigned individuals to correct response categories.
