Maximus is a government services and technology company.
If your issue relates to a specific government program, benefit, appointment, assessment, or application administered by Maximus, the best route is to use the telephone number or contact information provided by that particular program. Maximus explicitly directs program participants to its program-support directory rather than to the McLean corporate switchboard. This is important because Medicaid, clinical assessments, Veterans programs, state benefits, and other services can each be handled by separate teams.
For general corporate matters, the headquarters number is 703-251-8500. Clinical Services participants can call 1-877-431-1388, while job applicants needing application or accessibility support can call 1-866-307-1477 Monday through Friday from 8:00 AM to 6:00 PM Eastern Time. Having the program name, state, case number, appointment details, or application information available can help the representative identify the correct team more quickly.

People filing a complaint against Maximus should first determine which government program or Maximus business unit is involved. A complaint about a Medicaid enrollment center, clinical assessment, Veterans medical exam, employment application, state benefits program, or federal service can follow different procedures. Keep your case number, program name, state, appointment date, notices, emails, screenshots, names of representatives, and any documents connected with the problem before starting the complaint process.
Begin with the Customer Service or support number listed for the specific Maximus-administered government program involved. Explain the issue clearly and provide the program name, state, case or application number, relevant dates, and previous communications. Ask the representative whether the complaint can be resolved directly or needs to be escalated to a supervisor or specialist. Write down the representative’s name and any reference number provided. Keep copies of notices and correspondence connected with the case.
If the first representative cannot resolve the issue, ask for review by a supervisor, program manager, clinical specialist, or appropriate escalation team. Explain what action has already been taken and what part of the complaint remains unresolved. Provide previous case numbers and supporting documents, but avoid sharing unnecessary sensitive information through unsecured channels. Ask when you should expect a response and whether the program has a formal grievance or appeal process. Keep notes of every conversation and follow-up deadline.
Many government programs administered by Maximus have formal appeal, grievance, reconsideration, or hearing procedures established by the government agency itself. If your dispute concerns eligibility, benefits, a clinical determination, assessment result, or other official decision, follow the appeal instructions in your decision notice rather than relying only on general Maximus Customer Service. Pay close attention to filing deadlines and required documentation. Submit copies of relevant evidence and retain proof that the appeal or grievance was received.
For a serious unresolved corporate matter, written correspondence can be directed to Maximus, Inc., 1600 Tysons Boulevard, Suite 1400, McLean, VA 22102. Include your full contact information, the Maximus program or business unit involved, case or reference numbers, important dates, and a concise chronological explanation of the complaint. Clearly state the resolution you are requesting and include copies rather than originals of relevant records. Keep a complete copy of the correspondence and proof of mailing or delivery.
Because Maximus generally performs services under government contracts, unresolved complaints can sometimes need to be raised with the federal, state, or local agency responsible for the underlying program. For example, Medicaid, public benefits, Veterans services, health assessments, and employment programs can each have different oversight bodies and appeal rules. Use the agency named on your official notice or program documents rather than assuming one regulator handles all Maximus complaints. Keep case records, notices, call logs, and written responses before escalating externally.
