The reasons are not clear, but America's Health Insurance Plans (AHIP) received fewer insurer responses for its 2015 health-deductible health plan (HDHP) survey than it received for its 2014 HDHP survey.
AHIP, a trade group for health insurers, says it emailed survey forms to 109 member and non-member insurers this year, down from 113 in 2014.
The number of insurers that responded to the survey dropped 7.5 percent — to 64, from 80.
The number of insurers that received the survey form before 2014 was not immediately available, but the number of HDHP survey respondents is down from a peak of 95 in 2012.
The number of HDHP survey respondents is the lowest number AHIP has recorded in the past six years.
The drop could reflect methodological problems, such as the difficulty of getting emails through more aggressive spam filters, or the effects of Patient Protection and Affordable Care Act (PPACA) demands on insurers' ability to find time to fill out survey questionnaires.
