Here's an interesting article outlining what would happen if the ACHA is enacted as it currently stands. For ex: Nov. 1, 2017: “Open enrollment,” the period when potential enrollees can sign up for health insurance plans for the following year, begins for the first time under the AHCA. People logging onto (let’s call it) Trumpcare.gov find that they’ll pay substantially higher premiums compared with prior years, and many of their plans are no longer available. With insurers now permitted to charge older people as much as five times what they charge younger individuals — instead of three times or more under Obamacare — older Americans see their premiums soar. What’s more, the AHCA’s tax credits for many older people are less generous than the ACA’s were, so they have less help with payments." https://www.washingtonpost.com/posteverything/wp/2017/05/05/who-gets-hurt-and-when-if-trumpcare-becomes-law/?tid=sm_tw&utm_term=.7454f39cde05
