Brief report: Quantifying the impact of autism coverage on private insurance premiums.

Nikolov et al. (2009) asked a simple question: if states force private insurers to cover autism care, how much will premiums go up?

They ran an actuarial model using national claims data. The model assumed more kids would access ABA, speech, and occupational therapy once coverage became law.

The headline number is small. Premiums would rise about 1%, with a range from 0.19% to 2.31%.

For a family paying $500 a month, that is roughly an extra $5.

Barrett et al. (2015) extends the story. They tracked real UK teens for six months and found one autistic student can rack up £11,029 in school and health costs. The 1% premium bump looks tiny next to these downstream bills.

Lokhandwala et al. (2012) and McMaughan et al. (2023) show why the bills pile up. Autistic people stay in the hospital 55% longer and land in mental-health crises 11 times more often. Early coverage that prevents crises could save more than the 1% it costs.

Cimera et al. (2009) adds a twist from the same year. VR agencies spent the most on autistic adults yet saw them work fewer hours. The 1% premium projection does not include lost wages, so the full economic picture is bigger than the model shows.

Use the 1% figure when you talk to funders, families, or HR departments. It is a concrete, low-stakes number that unlocks doors to ABA, speech, and mental-health care. Pair it with hospital-cost data to show that coverage is cheaper than crisis care.
