This page presents a chronology of Medicaid ABI Waiver concerns, state complaints, federal reports, and preservation by David Medeiros. Build an eight-stage trail: observation, original record, governing rule, requested action, agency response, escalation, preserved artifact, and verified outcome. Keep the author's allegations about steering, kickbacks, retaliation, discrimination, record loss, and agency failure labeled as allegations unless primary evidence or an authorized finding supports them. Medicaid provider choice and HCBS assurances supply legal context, but they do not decide the facts of a specific case. A grievance, records request, complaint number, hash, referral, closure, delay, or missing document is evidence of that event, not proof of wrongdoing or motive. Use dates and distinguish discovery from later interpretation. Review the chronology at david-medeiros.com/federal-timeline.
