This section applies to a carrier with respect to any health benefit plan that is a grandfathered health plan, as defined in § 1251 of the Affordable Care Act. In addition to any other requirement under this article, a carrier shall: have demonstrated the capacity to administer the health benefit plan, including adequate numbers and types of administrative personnel; have a satisfactory grievance procedure and ability to respond to enrollees’ calls, questions, and complaints; provide, in the case of individuals covered under more than one health benefit plan, for coordination of coverage under all of those health benefit plans in an equitable manner; and design policies to help ensure adequate access to providers of health care. A person may not offer a health benefit plan in the State unless the person offers at least the Standard Plan. A carrier may not offer a health benefit plan that has fewer benefits than those in the Standard Plan. A carrier may offer benefits in addition to those in the Standard Plan if: the additional benefits: are offered and priced separately from benefits specified in accordance with § 15–1207 of this subtitle; and do not have the effect of duplicating any of those benefits; and the carrier: clearly distinguishes the Standard Plan from other offerings of the carrier; indicates the Standard Plan is the only plan required by State law; and specifies that all enhancements to the Standard Plan are not required by State law. Notwithstanding subsection (c) of this section, a health maintenance organization may provide a point of service delivery system as an additional benefit through another carrier regardless of whether the other carrier also offers the Standard Plan. A carrier may offer coverage for dental care and services as an additional benefit. In this subsection, “prominent carrier” means a carrier that insures at least 10% of the total lives insured in the small group market. A prominent carrier shall offer a wellness benefit for a health benefit plan offered under this subtitle. A carrier that is not a prominent carrier may offer a wellness benefit for a health benefit plan offered under this subtitle. A carrier may not condition the sale of a wellness benefit to a small employer on participation of the eligible employees of the small employer in wellness programs or activities.
