CO-32: Patient Not Eligible Dependent

What Does CO-32 Mean?

With CO (Contractual Obligation), the CARC 32 adjustment is the provider's responsibility. The payer denied or reduced payment because of dependent exceeded the age limit for coverage under the subscriber's plan (typically age 26 under ACA). The patient is not liable for this amount. If the denial is in error, the provider can correct and resubmit the claim or file an appeal with supporting documentation.

CARC 32 indicates patient not eligible dependent. The payer determined that the service or a portion of it does not meet coverage criteria under the patient's current plan benefits or the applicable coverage rules.

Common scenarios that trigger this adjustment include: dependent exceeded the age limit for coverage under the subscriber's plan (typically age 26 under ACA); The dependent was never added to the subscriber's insurance plan; The patient's relationship to the subscriber does not qualify for dependent coverage per plan rules. The group code paired with CARC 32 determines who bears the financial responsibility — CO places it on the provider as a contractual obligation, PR shifts it to the patient, OA indicates a coordination of benefits or other payer adjustment.
