Medicaid Patient Liability in Arkansas: How It's Calculated

Once a parent qualifies for Medicaid nursing home coverage in Arkansas, the state does not pay the entire facility bill. The resident is required to contribute most of their monthly income toward the cost of care. This contribution is called the patient liability — and understanding how it is calculated is essential because it determines how much money the community spouse actually gets to keep each month.

The Patient Liability Formula

Arkansas calculates patient liability using a straightforward subtraction formula:

Patient Liability = Gross Countable Income − (Personal Needs Allowance + Spousal Income Allowance + Medicare/Insurance Premiums + Non-Covered Medical Expenses + Mandatory Expenses)

Everything left after the deductions goes directly to the nursing facility. The resident does not choose how to spend this remaining amount — it is paid to the facility as their share of the cost of care, with Medicaid covering the difference between the patient liability and the facility's actual Medicaid rate.

The Deductions, Explained

Personal Needs Allowance (PNA): The resident keeps $40 per month for personal items — toiletries, clothing, haircuts, reading materials. If the resident's only income is SSI, the PNA drops to $30. This is a fixed amount set by the state and is not negotiable.

Spousal Income Allowance (MMMNA): If the resident has a community spouse, a portion of the resident's income is diverted to that spouse to prevent financial hardship. The spousal allowance is calculated based on the community spouse's own income relative to the Minimum Monthly Maintenance Needs Allowance:

• The MMMNA floor in Arkansas is $2,705 per month (effective July 1, 2026 through June 30, 2027)
• The MMMNA ceiling is $4,066.50 per month
• If the community spouse's independent income is below the floor, the shortfall is made up from the resident's income

For example: if the community spouse earns $1,200 per month from Social Security and the MMMNA is $2,705, the shortfall is $1,505. That $1,505 is deducted from the resident's income before calculating the patient liability.

The community spouse can push their allowance above the $2,705 floor (effective July 1, 2026 through June 30, 2027; up to the $4,066.50 ceiling) by demonstrating high shelter costs that exceed the Excess Shelter Standard of $811.50 per month. Shelter costs include rent or mortgage payments, property taxes, homeowners insurance, and the Arkansas Standard Utility Allowance of $342 per month.

Medicare and insurance premiums. Medicare Part B premiums, supplemental insurance (Medigap) premiums, and any other health insurance premiums the resident pays are deducted before calculating the patient liability.

Non-covered medical expenses. Medical expenses not paid by Medicaid or any other insurance — such as dental care, eyeglasses, or hearing aids — can be deducted if approved by the DHS caseworker.

Mandatory expenses. Court-ordered obligations like garnishments, bankruptcy payments, or guardianship fees are deducted.

A Worked Example

Consider a single resident with the following monthly income:

• Social Security: $1,800
• Pension: $600
• Total gross countable income: $2,400

Deductions:

• Personal Needs Allowance: $40
• Medicare/insurance premium (illustrative): $185
• Total deductions: $225

Patient liability: $2,400 − $225 = $2,175 per month paid to the nursing facility.

Now consider a married resident with the same income, but with a community spouse earning $1,000 per month:

• Gross countable income: $2,400
• Personal Needs Allowance: −$40
• Spousal Income Allowance: −$1,705 (the community spouse needs $2,705, earns $1,000, shortfall is $1,705)
• Medicare/insurance premium (illustrative): −$185
• Patient liability: $2,400 − $40 − $1,705 − $185 = $470 per month

The difference is dramatic. The married resident's patient liability is $470 compared to $2,175 for the single resident, because the spousal allowance redirects most of the income to the community spouse.

How the Miller Trust Fits In

If the resident's countable income exceeds $2,982 per month (the 2026 income cap), countable income above $2,982 must be placed into a Qualified Income Trust (Miller Trust) in the month received. The trust does not change the patient liability calculation — it simply provides the legal mechanism to make the resident eligible despite the over-income status.

The trustee distributes the trust funds in a specific priority order: PNA first, then spousal allowance, then trustee/bank fees, then insurance premiums, then non-covered medical expenses, then mandatory expenses. Whatever remains after all authorized deductions is the patient liability, paid directly to the nursing facility.

The trustee must notify the DHS caseworker of any changes in income, premiums, or medical expenses that alter the monthly calculation. Getting this wrong — distributing funds out of order or retaining more than authorized — can trigger a disqualification.

Why This Matters for Planning

The patient liability calculation determines the community spouse's actual financial position. Families who understand the formula can take steps to maximize the spousal allowance — documenting high shelter costs to push the MMMNA toward the ceiling, ensuring all deductible expenses are claimed, and coordinating insurance premiums effectively.
