Yes. Everything is guaranteed issue unless you go with one of those weird Christian health insurance things. Insurance companies can't deny coverage now because of a pre-existing condition, and they can't go back and deny claims because of something someone put on an application. No one gets their insurance dropped because they get bone cancer and THEN a claims adjuster went and poured over their original application.
"Before private insurance market rules in the Affordable Care Act (ACA) took effect in 2014, health insurance sold in the individual market in most states was medically underwritten.1 That means insurers evaluated the health status, health history, and other risk factors of applicants to determine whether and under what terms to issue coverage."
"Prior to the ACA’s coverage expansions, we estimated that 18% of individual market applications were denied. This is an underestimate of the impact of medical underwriting because many people with health conditions did not apply because they knew or were informed by an agent that they would not be accepted. Denial rates ranged from 0% in a handful of states with guaranteed issue to 33% in Kentucky, North Carolina, and Ohio. According to 2008 data from America’s Health Insurance Plans, denial rates ranged from about 5% for children to 29% for adults age 60-64 (again, not accounting for those who did not apply)."
