Medicare won’t reimburse amounts related to SOC for Medicaid. If the patient is responsible for SOC, then the patient responsibility amount is sent to collections and deemed uncollectible. You’re still allowed to report the Medicare coinsurance or deductible amounts on the report, but it must not include the SOC amount as a traditional bad debt.
In the case that the patient was eligible for Medicaid and paid the SOC portion, the remaining amount related to the Medicare coinsurance or deductible would then be billed to Medicaid, denied, and then you could capture them as a crossover.
