“Medicaid coverage includes a wide variety of preventive, primary, and acute care services as well as LTSS [Long-Term Services and Supports].³⁶ Not everyone enrolled in Medicaid has access to the same set of services. An enrollee’s eligibility pathway determines the available services within a benefit package. Federal law provides two primary benefit packages for state Medicaid programs: (1) traditional benefits and (2) alternative benefit plans (ABPs). Each of these packages is summarized in Table 1. For the medically needy subgroup, states may offer a more restrictive benefit package than is available to other enrollees. In addition, states can use waiver authority (e.g., SSA Section 1115) to tailor benefit packages to specified Medicaid subgroups as well as offer services outside traditional or ABP coverage, such as LTSS (see ‘Medicaid Program Waivers’ for more information about Section 1115 waivers).”

“Traditional Medicaid benefits include primary and acute care as well as LTSS. The traditional Medicaid program requires states to cover a wide array of mandatory services (e.g., inpatient hospital care, lab and x-ray services, physician care, nursing facility services for individuals aged 21 and older). In addition, states may provide optional services, some of which commonly are covered (e.g., personal care services, prescription drugs, clinic services, physical therapy, and prosthetic devices).

“States define the specific features of each covered benefit within four broad federal guidelines:

“ Each service must be sufficient in amount, duration, and scope to reasonably achieve its purpose. States may place appropriate limits on a service based on such criteria as medical necessity.

“ Within a state, services available to the various population groups must be equal in amount, duration, and scope. This requirement is the comparability rule.

“ With certain exceptions, the amount, duration, and scope of benefits must be the same statewide, referred to as the statewideness rule.

“ With certain exceptions, enrollees must have freedom of choice among health care providers.

“The breadth of coverage for a given benefit can, and does, vary from state to state, even for mandatory services. For example, states may place different limits on the amount of inpatient hospital services a beneficiary can receive in a year (e.g., up to 15 inpatient days per year in one state versus unlimited inpatient days in another state)—as long as applicable requirements are met regarding sufficiency of amount, duration, and scope; comparability; statewideness; and freedom of choice. Exceptions to state limits may be permitted under circumstances defined by the state.”

“As an alternative to providing all the mandatory and selected optional benefits under traditional Medicaid, the Deficit Reduction Act of 2005 (DRA; P.L. 109-171) gave states the option to enroll state-specified groups in what was referred to as benchmark or benchmark-equivalent coverage but currently are called alternative benefit plans (ABPs).³⁸ Under ABPs, states must provide comprehensive benefit coverage that is based on a coverage benchmark rather than a list of discrete items and services as under traditional Medicaid.

“ABPs must qualify as either benchmark or benchmark-equivalent coverage. Under benchmark coverage, ABP benefits are at least equal to one of the statutorily specified benchmark plans (i.e., one of three commercial health insurance products, or a fourth “Secretary-approved” coverage option).³⁹ Under benchmark-equivalent coverage, ABP benefits include certain specified services and the overall benefits are at least actuarially equivalent to one of the statutorily specified benchmark coverage packages.”
