State — Indicates the state for which the enrollment and contact data in the record is applicable.

Category — The program under which this plan is categorized by AIS--Dual-Eligible, Medicaid FFS, Medicaid HMO, Medicaid PCCM, Medicare Advantage, SCHIP, SCHIP FFS, or Stand-Alone PDP plan.

Medicare Advantage — Checkbox to indicate/select for plans that are part of Medicare Advantage, or Medicare Part C.

Managed Medicaid — Checkbox to indicate/select for plans that are part of Medicaid HMOs, which are contracted by state Medicaid agencies.

Medicaid FFS — Category refers to traditional Medicaid, in which a state Medicaid agency reimburses providers directly, as opposed to paying a monthly capitated rate to a managed care entity with its own provider network. A fee schedule dictates the allowed payment for each service.

Medicaid PCCM — Category refers to Primary Care Case Management, a method of care delivery in which a primary care provider or provider group closely coordinates enrollees’ health services, and is reimbursed through the state, plus an additional fee for their services. Overlaps Medicaid FFS category. PCCM records are pulled out where AIS researchers can identify them, as some states do not distinguish between PCCM enrollment and fee-for-service Medicaid.

Special Needs Plans — Checkbox to indicate/select for plans that are designated as Special Needs Plans. Includes the three types of SNPs: Chronic-Condition Special Needs Plans (C-SNP), Dual-Eligible Special Needs Plans (D-SNP) and Institutional Special Needs Plans (I-SNP). May overlap Medicare Advantage and/or Dual-Eliglbles categories.

PACE Plans — Checkbox to indicate/select for plans under the Program of All-inclusive Care for the Elderly (PACE). The majority of PACE members are Medicare-Medicaid Dual Eligibles, so AIS identifies them as such.

These plans serve people that are eligible for both Medicare and Medicaid under CMS-designated initiatives. Does NOT overlap Medicare Advantage or Medicaid HMO categories, but may overlap Special Needs Plans or PACE Plans (because D-SNPs and PACE plans serve dual-eligibles).

Stand-Alone PDPs — Checkbox to indicate/select for plans that offer prescription drug coverage only, under Medicare Part D, and do not have any medical benefits. Does not overlap any other categories.

Employer Group Waiver Plan — Employer-group waiver plans (EGWPs) are offered to Medicare-eligible retirees of a given employer. Like other Medicare Advantage plans, these plans cover all Medicare Part A and Part B benefits, plus possibly some supplemental benefits including Part D.
