Summary
Illinois confirms that biomarker testing remains covered under both Medicaid fee-for-service and managed care plans, following Public Act 102-0203. No coverage changes are necessary as the Department already covers this testing when supported by medical and scientific evidence for diagnosis, treatment, management, or monitoring.
Action Required
No immediate action required. This is a confirmation notice that existing biomarker testing coverage continues unchanged. Billing teams should continue current practices for biomarker testing claims with appropriate medical and scientific evidence documentation.
