A closed Medicaid system is an audit hypothesis, not a finding. Test five record sets. One: the current provider directory and what each family received before selection. Two: referral distributions across qualified willing providers, regions, services, and time. Three: person-centered plans, authorizations, claims, and provider-choice records. Four: institutional delays compared with available community capacity and each person's preferences. Five: contractor contracts, communications, grievances, accommodation decisions, and audit logs. Medicaid rules protect choice among qualified willing providers, subject to lawful exceptions. HCBS rules require informed choices and integrated settings. Concentrated referrals, missing records, or payment anomalies justify review; they do not prove steering, bias, retaliation, or fraud. Read the source-linked framework at david-medeiros.com.
