Idaho AABD Medicaid Income and Resource Limits for Disabled Adults

What AABD Medicaid Is and Why It Matters

AABD stands for Aged, Blind, and Disabled — it is Idaho's disability-specific Medicaid pathway, distinct from the Medicaid Expansion program that covers low-income adults regardless of disability status. The distinction matters enormously for adults with developmental disabilities because only AABD Medicaid (or the closely related MWD pathway) provides access to the Enhanced Plan, which is the mandatory foundation for DD waiver enrollment.

An adult who qualifies for Medicaid only through the Expansion pathway cannot access DD waiver services — even if they meet the ICF/IID level of care and have been approved by Liberty Healthcare's functional assessment. The waiver requires Enhanced Plan Medicaid, which is tied to the AABD or MWD eligibility category.

2026 Income and Resource Limits

Community-based AABD Medicaid:

• Monthly income limit: $1,047 for an individual
• Countable resource limit: $2,000 for an individual
• Income counted: all unearned income (SSI, SSDI, DAC benefits, pensions) minus a $20 general disregard; earned income minus a $65 earned income disregard plus one-half of remaining earnings

HCBS waiver income cap (for DD waiver participants):

• Monthly gross income limit: $3,002 (the 2026 state-applied HCBS cap)
• If income exceeds $3,002 by even $1, a Miller Trust (Qualified Income Trust) is required to maintain waiver eligibility

Key exclusions from countable resources:

• The individual's home, if it qualifies under Idaho's home-exclusion rules
• One vehicle
• Household furnishings and personal effects
• Burial plots and up to $1,500 set aside for burial
• ABLE account balances up to $100,000

AABD vs Medicaid Expansion: The Practical Differences

The counterintuitive result: Medicaid Expansion has a higher income limit and no asset test, but it provides less coverage for adults with developmental disabilities. Families sometimes see the Expansion pathway as "easier" because it lacks the asset test, without realizing it locks their adult child out of waiver services.

The AABD Cash Supplement

Idaho also administers a small state cash supplement through the AABD program — capped at $53 per month for individuals living independently in the community. This supplement is administered by DHW's Division of Welfare and requires the individual to be receiving SSI or meet the aged, blind, or disabled criteria independently. The $53 is in addition to the federal SSI payment.

The AABD cash supplement has its own living arrangement rules — the amount varies depending on whether the individual lives alone, with a spouse, or in a shared household. A denial of the cash supplement (which often happens when calculated shelter costs are low) has no bearing on DD waiver eligibility or budget.

How to Apply

AABD Medicaid applications go through the same idalink.idaho.gov portal used for all Medicaid categories. The application requires:

• Proof of disability (SSI award letter, or medical documentation if not receiving SSI)
• Income verification (pay stubs, benefit letters, bank statements)
• Resource documentation (bank accounts, investment statements, vehicle titles)
• Proof of Idaho residency

If the individual is receiving SSI, the SSI award letter effectively pre-verifies the disability component, but Idaho still requires DHW to determine Medicaid eligibility. The application process focuses mainly on verifying income, countable resources, and other state requirements.

The Idaho SSI at 18 & Adult Disability Benefits Guide includes a Benefits Eligibility Tracker that calculates countable income and resources across AABD, MWD, and Expansion pathways, showing which Medicaid category provides the best coverage for each family's situation.
