27.7 Cost of Care Calculation

27.7.1 Introduction

After an institutionalized person has been determined eligible for Medicaid, his or her cost of care must be calculated. Cost of care is the amount the person will pay each month to partially offset the cost of his or her Medicaid services. It is called the patient liability amount when applied to a resident of a medical institution, including those enrolled in Family Care, Family Care Partnership, or PACE who are in or likely to be in a medical institution for 30 or more days. Institutionalized people are expected to pay their patient liability to the institution they are residing in, or to their MCO if they are enrolled in Family Care, Family Care Partnership, or PACE, as of the first day of the month.

Calculate the cost of care in the following way:

  1. For a Medicaid member in a medical institution who does not have a community spouse , subtract the following from the person’s monthly income:
    1. $65 and ½ earned income disregardAn amount not counted when determining a person's total net income. (see Section 15.7.5 $65 and ½ Earned Income Deduction).
    2. Monthly cost for health insurance (see Section 27.6.4 Health Insurance).
    3. Support payments (see Section 15.7.2.1 Support Payments).
    4. Personal needs allowance (see Section 39.4 Elderly, Blind, or Disabled Assets and Income Tables).
    5. Home maintenance costs, if applicable (see Section 15.7.1 Maintaining Home or Apartment).
    6. Expenses for establishing and maintaining a court-ordered guardianship or protective placement, including court-ordered attorney and/or guardian fees (see Section 27.6.6 Fees to Guardians or Attorneys).
    7. Medical or remedial expenses (see Section 27.7.7 Medical or Remedial Expenses and Payments for Noncovered Services).
  2. For a Medicaid member in a medical institution who has a community spouse, follow the directions in Section 18.6 Spousal Impoverishment Income Allocation.
  3. For a community waivers member with or without a community spouse, follow the directions in Section 28.6.4 Cost Share Amount.
  4. There is no cost of care for SSISupplemental Security Income. A program based on financial need operated by the Social Security Administration that provides monthly income to low income people who are age 65 or older, blind, or disabled. recipients.
  5. For a Medicaid member who was or could have been certified through a deductible before entering the institution, there is no cost of care until the deductible period ends.
Note: 503, DAC, Widow or Widower, and COLA disregards that are used in eligibility determinations for Special Status Medicaid are not used in Patient Liability Calculations.

If the cost of care amount is equal to or more than the medical institution’s Medicaid rate, the individual is responsible for the entire cost of his or her institutional care. He or she would be entitled to keep any overage without restriction. He or she would remain eligible for the Medicaid program and have no further financial obligation to the Medicaid program for that month.

27.7.2 Hospitalized People

Effective December 1, 2008, hospitalized people will be responsible for paying a patient liability. See Section 27.7.4 Transfers Between Institutions for information about patient liability calculations when a person transfers between a hospital and nursing home(s).

27.7.3 Partial Months

If a member is residing in an institution (see Section 27.1 Institutions) and not Medicaid-eligible as of the first of the month, there is no patient liability for that month.

If a member was not institutionalized as of the first of the month or was discharged to the community prior to and including the last day of the month, there is no patient liability. However, if the member is enrolled in Family Care, Family Care Partnership, or PACE, he or she may owe a cost share to the MCO if a cost share is determined following the change in living arrangement.

Exceptions:

27.7.3.1 Death

If the patient liability amount in the month of death is greater than the nursing home’s cost of care for that month and the nursing home or entity responsible for collecting the patient liability requests it, the patient liability can be adjusted to be equal to the nursing home charges for that month (see Process Help 11.2.2.3).

27.7.3.2 Community and Nursing Home

There is no patient liability in a month in which a member moves from one of the following:

27.7.4 Transfers Between Institutions

Effective December 1, 2008, when an institutionalized person transfers between institutions (nursing homes, hospitals, hospices) in the same month, do not prorate the patient liability between the various institutions that he or she resided in during that month. The member will pay his or her patient liability to the institution that he or she were residing in on the first day of the month. ForwardHealth will automatically deduct the appropriate patient liability amount from the first nursing home, hospice, or long term inpatient hospital claim received for the member. If the amount of the patient liability exceeds the reimbursement amount of the first claim, the remaining liability amount will be deducted from the next claim(s) received for services provided in the month that patient liability is owed. Patient liability amounts deducted from claims will appear in the provider’s remittance information. Nursing home, hospice, and inpatient hospital providers may have to occasionally transfer a patient liability amount that they collected from a member on the first day of a month to the appropriate provider who ultimately had the claim adjusted to reflect the required patient liability amount.

27.7.5 Retroactive Cost of Care

Occasionally a nursing home or community waivers applicantA person who has submitted a request for coverage for whom no decision has been made regarding eligibility becomes retroactively eligible. This might happen, for example, when a person, having been denied eligibility, goes to a fair hearing. If the fair hearing determines the person was eligible at the time of application, the agency must retroactively certify him or her and compute retroactive cost of care. The directions are the same as for current cost of care (see Section 27.7.1 Introduction).

27.7.6 Personal Needs Allowance

Deduct the personal needs allowance (see Section 39.4.3 LTC Post-Eligibility Allowances) for all institutionalized members in both the eligibility test and the patient liability calculation.

An institutionalized person's personal needs allowance may accumulate to where he or she may lose eligibility due to excess assets. To prevent this, he or she can spend money on personal needs or make a refund to Medicaid (see Section 22.1.9 Voluntary Recovery [Not Estate Recovery Program]).

27.7.7 Medical or Remedial Expenses and Payments for Noncovered Services

27.7.7.1 Introduction

Medicaid members in nursing homes are allowed to pay for some medically necessary noncovered services out of their patient liability. They are not required to use their personal needs allowance for these services.  

Effective January 4, 2008, medical or remedial expenses an institutionalized applicant or member has incurred, is actually paying, and is legally obligated to pay are allowable expenses and are used as a need item when determining his or her eligibility for Medicaid. These actual payments are also allowed as an income deduction to reduce the cost share or patient liability amount. This includes payments for medical or remedial expenses that the institutionalized applicant or member is currently incurring as well as payments for certain previously incurred medical or remedial expenses.

Note: This does not include any medical or remedial expenses that another person has incurred.

In order to use the medical or remedial expense as a need item and as an income deduction in the cost share calculation, the expense must meet both the following criteria:

Example 1: In February, Al had a root canal performed by a dentist who is not an Medicaid provider. He is responsible for paying $600 for the procedure. Al began making payments of $100 per month on this medical bill in March. On April 1, Al became institutionalized and eligible for Medicaid. The $100 payment that Al is making on a previously incurred medical expense should be used as a need item when determining Al’s institutional Medicaid eligibility. The expense should also be used as in income deduction when calculating Al’s cost share obligation. The $100 payment can be used as an income deduction in the cost share calculation until it is fully paid in August. Since Al will no longer be making payments in September, the expense should be decreased to zero prior to adverse action in August.

 

Example 2: In April, Edna applied for institutional Medicaid and requested a one month backdate. Her request for eligibility in March was denied because her assets exceeded program limits, but was approved effective April 1. Edna used her excess assets to make a partial payment to the nursing home for March costs, but still has an outstanding balance of $1,800. Edna agrees to make payments to the nursing home of $500 per month until the expense is paid in full. The $500 payment to the nursing home should be used as an income deduction when calculating her cost share for the months of April through June. In July, she will only owe $300 to the nursing home so the deduction for July should be decreased to $300 prior to adverse action in June. Edna will no longer be making payments in August, so the expense should be decreased to zero prior to adverse action in July.

 

Example 3: Jack has been an institutionalized Medicaid member since January. In March, he had a tooth extracted. The procedure was performed by a dentist who is not an Medicaid provider, so it was a noncovered service. Jack contacts the agency in April to request a deduction from his cost share so that he can pay the expense. The cost of the extraction was $209. Since this was a one-time expense and his patient liability exceeds this amount, the agency enters the expense in CWWCARES Worker Web to reduce the May cost share by $209.

27.7.7.2 Disallowed Expenses

Do not allow payments that an institutionalized person is making, or requests to make, as a need item or as a cost share adjustment if the medical or remedial expense meets any of the following exception reasons:
