A Medi-Cal Notice of Action (NOA) is a written notice that gives Medi-Cal applicants and beneficiaries an explanation of their eligibility for Medi-Cal coverage or benefits.  The NOA should include the eligibility decision and effective date of coverage, as well as any changes made in your eligibility status or level of benefits.  The NOA must also include information about your hearing rights and how to appeal the decision if you disagree with the eligibility determination.
