CO-132: Prearranged Demonstration Project Adjustment

What Does CO-132 Mean?

With CO (Contractual Obligation), the CARC 132 adjustment for prearranged demonstration project adjustment is a contractual reduction. The provider absorbs this amount per the payer contract or regulatory payment methodology. The patient is not responsible for the adjusted amount. Review the remittance to confirm the adjustment is consistent with your contract terms.

CARC 132 appears on a remittance when the payer applies an adjustment for prearranged demonstration project adjustment. Review the group code and any accompanying RARC codes to understand the full context of this adjustment.

Common scenarios that trigger this adjustment include: the provider participates in a CMS Innovation Center demonstration project, and CARC 132 reflects the adjusted payment per the project's specific payment methodology; Under a bundled payment demonstration, the payment is adjusted to reflect the episode-based payment rather than fee-for-service rates; The provider participates in a value-based payment demonstration, and the payment is adjusted based on quality and cost performance metrics. The group code paired with CARC 132 determines who bears the financial responsibility — CO places it on the provider as a contractual obligation, OA indicates a coordination of benefits or other payer adjustment, PR shifts it to the patient.
