HB 5512 modifies Medicaid provider enrollment and credentialing processes, specifically affecting eye health care and vision care providers. It requires the Texas Health and Human Services Commission to establish a support team to assist Medicaid providers with enrollment and credentialing. It also mandates that Medicaid managed care organizations (MCOs) cannot use third-party insurers or vision plans to determine a provider's eligibility for Medicaid reimbursement. The bill enforces direct contracting between MCOs and vision care providers and ensures that reimbursements for eye health services meet or exceed Medicaid fee-for-service rates​.
