Share of Cost Medicaid and Medically Needy Medicaid

Definition: Share of Cost (SOC)

It is easiest to think of Share of Cost (SOC) as a partial acceptance into the Medicaid program (or Medi-Cal in California). It is intended to assist individuals whose incomes exceed the Medicaid limit but who have unusually high medical expenses which they cannot afford. Share of Cost works as follows; the state reviews an individual's income and medical needs and costs to determine if they can afford their necessary care. If it is decided they cannot afford their care, the state decides how much of their monthly income they can afford to pay towards their care and then the state Medicaid program covers the remainder of the cost.

Think of Share of Cost like an insurance deductible but one that must be met each month instead of each year. For example, an elderly woman has monthly income of $1,200 and the state determines she needs $800 of that to live on each month (this is referred to as her "monthly maintenance need"). Under Share of Cost, she would be required to pay the additional $400 / month to her medical providers. Her "Share of Cost" would be $400. Any medical expenses she has in excess of the $400 will be paid by the state

If, in any given month, she does not have over $400 in medical bills, she pays only her expenses and is allowed to keep the remainder. For example, in June her income is $1,200 and she has $300 in medical expenses. She keeps her $800 monthly maintenance need, pays the $300 in medical bills and keeps the remaining $100 of her income, so in June she has a true income of $900.

Share of Cost vs. Deductibles & Co-Pays

Share of Cost (SOC) and insurance deductibles are similar in that once the consumer has spent a specific amount, then insurance covers the remainder. However, deductibles are at a set level shared by everyone in a particular type of insurance. Share of Cost is specific to the individual. One can think of SOC as a custom deductible based on one's income and medical expenses.

Co-pays, or co-payment amounts, are the portion of a specific medical expense for which the consumer is responsible. This is different from SOC because with SOC all medical expenses are considered in aggregate while with co-payments each procedure or medication will have a specific co-payment amount.

Alternatives to Share of Cost

If one thinks of Share of Cost as a partial acceptance into Medicaid, then one can avoid Share of Cost by being fully or unconditionally accepted into Medicaid.  Qualifying for Medicaid unconditionally means the individual has income and assets less than the eligibility limits.  In 2016, in most states for elderly persons living at home, single applicants must have less than $2,199 in monthly income and less than $2,000 in assets excluding their home and vehicle.  Details available here.

There are multiple techniques used to lower one's income and assets to meet Medicaid eligibility limits yet still preserve those assets for one's family.  Read about pooled income trusts, which help lower one's income and funeral trusts which lower one's assets.

Qualifying for Medicaid is complicated, there are professional advisors, both public and private, that help families to qualify. Medicaid is managed at the state level; find a Medicaid Planner in your area to help.
