In a significant new case out of California, the United States Circuit Court of Appeals (Ninth Circuit)[1] in California Insurance Guarantee Association (CIGA) v. Azar, 2019 WL 5076945 (9th Cir. Oct. 10, 2019) reversed the United States District Court for the Central District Court of California [2] and ruled that CIGA is not a “primary plan” under the Medicare Secondary Payer (MSP) statute and, therefore, not liable to reimburse Medicare conditional payments made on behalf of workers’ compensation claimants.
