OA-178: Patient Has Not Met Spend Down Requirements

What Does OA-178 Mean?

With OA (Other Adjustments), the spend down issue was flagged during coordination of benefits processing. This may occur when Medicaid is the secondary payer and the primary payer's payment did not fully resolve the spend down requirement. Review the COB details to determine the correct payer responsibility.

CARC 178 appears when a patient's Medicaid eligibility is contingent on meeting a monthly spend down requirement and that threshold has not yet been reached. Spend down works similarly to a deductible — the patient must incur a specified dollar amount of medical expenses each month before Medicaid coverage activates.

This code is specific to Medicaid programs that use spend down as an eligibility mechanism. The patient's income exceeds the Medicaid threshold, but they qualify for coverage once their medical expenses bring their effective income below the limit. Until the patient submits enough qualifying medical bills to the state and the spend down is verified as met, claims will be denied under this code.

How to Resolve

1. Review the COB details Examine the remittance from each payer to understand how the spend down was applied in the coordination chain.
2. Verify spend down accumulation across payers Confirm whether payments from the primary payer count toward the Medicaid spend down.
3. Resubmit if appropriate If the spend down has been satisfied by other expenses or payer payments, resubmit with documentation.

How to Prevent OA-178

• Track spend down accumulations across all payers in the coordination chain
• Verify Medicaid spend down status before submitting secondary claims
