What Is an Institutional Special Needs Plan (ISNP)?

An Institutional Special Needs Plan (ISNP) is a specific type of Medicare Advantage plan designed for individuals who require long-term care services in a residential setting. These plans provide comprehensive, coordinated health coverage, replacing Original Medicare (Parts A and B) and including prescription drug coverage (Part D). This structure allows for personalized medical management for individuals with complex, ongoing health needs.

Understanding Institutional Special Needs Plans

ISNPs fall under the umbrella of Medicare Special Needs Plans (SNPs), which are coordinated care plans approved by the Centers for Medicare & Medicaid Services (CMS) to serve individuals with specific needs. Unlike standard Medicare Advantage plans, SNPs restrict enrollment to beneficiaries who meet certain criteria, such as having certain chronic conditions or being eligible for both Medicare and Medicaid. Institutional Special Needs Plans focus specifically on those whose medical needs are best met within a long-term care environment.

The defining characteristic of an ISNP is its focus on the “institutional setting” where the beneficiary resides. This includes facilities like skilled nursing facilities, long-term care hospitals, and intermediate care facilities for individuals with intellectual disabilities. These plans are structured to bring medical services directly to the patient, minimizing the need for travel to external appointments and reducing disruption to their daily routine. This model ensures that the full range of Medicare benefits is delivered in a manner consistent with the facility’s operations and the member’s daily life.

Who Qualifies for an ISNP

To be eligible for an ISNP, an individual must first be entitled to Medicare Part A and enrolled in Medicare Part B. Beyond this basic requirement, the individual must satisfy the plan’s institutional criteria, which is the defining factor for enrollment. A person qualifies if they have lived or are expected to live in a qualifying institutional setting for 90 consecutive days or longer.

Qualifying institutional settings include skilled nursing facilities, nursing facilities, and inpatient psychiatric facilities. Alternatively, an individual may qualify if they require an institutional level of care, even if they currently reside in the community. This “institutional level of care” determination is made by the state using a standard assessment tool to confirm the need for daily skilled nursing or rehabilitative services. The assessment must be administered by an impartial, independent party to ensure an accurate determination of the individual’s long-term care needs.

The Integrated Care Model and Benefits

The primary advantage of an ISNP is its integrated care model, which is designed to manage the comprehensive and complex needs of its members. This model is built around an interdisciplinary care team that works with the facility staff to coordinate services. This team often includes a dedicated Nurse Practitioner, an RN Care Coordinator, primary care physicians, and behavioral health specialists.

The care team develops a personalized Model of Care (MOC) for each member, which outlines how all medical and support services will be delivered. This coordinated approach ensures seamless transitions of care, especially when a member moves between the facility, a hospital, or another care setting. By having providers who specialize in the institutional environment, the plan can focus on managing chronic conditions proactively and reduce avoidable hospitalizations.

ISNPs integrate Medicare Part A (hospital services), Part B (medical services), and Part D (prescription drugs) into a single plan. This unified structure simplifies the administration of care and provides greater coverage for specialized services. Many ISNPs also coordinate benefits with Medicaid for individuals who are dually eligible for both programs. This coordination is beneficial because it simplifies payment and service delivery for facility residents who often rely on Medicaid for long-term supports and services. Supplemental benefits commonly offered include vision, dental, hearing, and allowances for over-the-counter products, which directly enhance the member’s quality of life within the facility.

How to Enroll and Manage Your Plan

The enrollment process for an ISNP is often simpler than for standard Medicare plans because a Special Enrollment Period (SEP) is triggered by institutional status. This SEP, sometimes referred to as the Open Enrollment Period for Institutionalized individuals, permits enrollment or plan changes at any time while the individual resides in a qualifying facility. This continuous enrollment opportunity recognizes the urgent and ongoing nature of the member’s need for specialized care.

To find an ISNP, you must confirm that one is available in your geographic area and that the specific long-term care facility is contracted with the plan. Since ISNPs are offered by private insurance companies, plan availability is limited and varies significantly by county and state.

Upon discharge, the member maintains their ISNP coverage for a limited period to allow for a smooth transition, typically for two months after the month they leave the institution. During this transition period, the individual must select a new health plan, such as a standard Medicare Advantage plan or Original Medicare. This rule ensures that the specialized benefits of the ISNP are reserved for those who continue to meet the institutional level of care requirement.
