The Affordable Care Act includes a long list of codified instructions about what's required under the law. However, like any major piece of legislation, many of the specific details are left up to the agency responsible for implementing the law.
While the PPACA is itself a lengthy document, it would have to be several times longer yet in order to cover every conceivable detail involved in operating the ACA exchanges, Medicaid expansion and so forth. The major provisions of the ACA fall under the Department of Health & Human Services (HHS), and within that, the Centers for Medicare & Medicaid (CMS)
Every year, CMS issues a long, wonky document called the Notice of Benefit & Payment Parameters (NBPP) for the Affordable Care Act. This is basically a list of proposed tweaks to some of the specifics of how the ACA is actually implemented for the following year (actually, it's the year after the following year, since the final rule is generally released in mid-December).
CMS Approves Added Benefits to Essential Health Benefits (EHB) Benchmark Plans in North Dakota and Virginia
September 6: CMS approved added benefits to the Essential Health Benefits (EHB) benchmark plans for North Dakota and Virginia for the 2025 plan year. The Affordable Care Act requires non-grandfathered health plans in the individual and small group markets to cover essential health benefits (EHB), which include items and services in ten benefit categories. For plan year 2020 and after, the Final 2019 HHS Notice of Benefits and Payment Parameters provides states with greater flexibility by establishing new standards for states to update their EHB-benchmark plans, and for tailoring them to fit the health care needs of their states.
Here's the best summaries I could find of the additional benefits for each state:
