What 142 means

Part of the payment was withheld because the patient owes a monthly share toward their care under Medicaid rules.

Some Medicaid recipients, often those in nursing homes or on long-term care programs, must pay a set amount of their own income each month toward their care. The payer has subtracted that amount from this claim.

The amount is usually the patient's or their representative's to pay. Check that the liability amount matches the figure set by the Medicaid agency for that month.

Group codes seen with 142

On a remittance, 142 comes after a group code. These are the ones it is most often reported with:

• PR 142 (Patient Responsibility): The amount is assigned to the patient. Deductibles, coinsurance and copays are the everyday examples. Whether you can collect it still depends on your contract and the patient's plan.

The payer chooses the group code for each adjustment, so the same reason code can appear with another group code on your remittance. Read the two together. More about group codes.

Common causes

• The patient has a monthly income-based share of cost set by the state Medicaid agency.
• The claim is the first one in the month, so the full monthly liability was applied to it.
• The patient's liability amount changed and the payer used the updated figure.

What to do next

1. Compare the deducted amount with the patient's current monthly liability notice.
2. Bill the patient or their representative for the liability amount if it matches the notice.
3. Contact the Medicaid agency or payer if the amount was applied twice or in the wrong month.
