OA 23 denials

Can anyone please help? I have a patient who has Medicare as primary and Aetna as a secondary. Medicare denied a portion of the claim and applied it to her co insurance but Aetna denied it also for OA-23 (payment denied because of another payer). Would the patient be responsible for the co insurance?



Thank you!

re: OA 23 denials

If Medicare applied it to her co-insurance, its should be the patient's responsibility. Why would Aetna denied the claim if Medicare applied to her co-ins? Her secondary (Aetna) must not pick up the co-ins. depending on the patient's benefit plan.
