Maryland Department of Health phone, local offices, Medicaid, Vital Records, WIC, ImmuNet and official service help

What this Maryland Department of Health guide covers
Maryland Department of Health phone number directory by service

Maryland Department of Health main address, office and map
MDH lists its main office at 201 W. Preston Street, Baltimore, MD 21201. The listed general phone numbers are 410-767-6500 and 1-877-463-3464.
Do not assume this building is the correct place for every task. Vital Records, local health departments, licensing boards, Medicaid, WIC and OHCQ may use separate pages, units, appointment rules or locations.
Maryland local health departments near me: county and Baltimore City services
Maryland local health departments are often the practical front door for local services. The MDH directory links to county health departments and Baltimore City Health Department websites.
Use local health departments for county clinic schedules, WIC offices, immunization clinics, community health programs, local alerts, disease reporting support, environmental health contacts and some certificate services.
For broader local-office help, see our health department near me guide.
Maryland birth certificates, death certificates, marriage certificates and divorce verifications
The Maryland Vital Statistics Administration handles certified copies of Maryland birth, death, fetal death and marriage certificates, plus divorce verifications. The Division of Vital Records lobby is listed as appointment-only.
Some local health departments also provide certain birth and death certificate services, but the county list shows that hours, appointment rules, fees and payment methods vary by county.
| Record need | Official route | Important caution | Prepare before requesting |
|---|---|---|---|
| Maryland birth certificate | Division of Vital Records, local health department where available, mail or official request route. | Eligibility, ID and request method matter.

For general certificate process help, see our Department of Health birth certificate guide.
Maryland ImmuNet, MyIR Mobile and vaccine record help
ImmuNet is Maryland’s immunization information system. MDH describes it as a confidential, secure and HIPAA-compliant database that stores vaccination records across the state.
For public vaccine record access, use official ImmuNet/MyIR guidance, your healthcare provider, your child’s school health office, a pharmacy or your local health department. Missing records may require contacting the provider that gave the vaccine.
Before requesting an immunization record
- Use the exact legal name and date of birth used when vaccines were given.
- Collect old vaccine cards, school forms, pharmacy records and provider printouts.
- Know the deadline: school, camp, employment, travel, daycare or healthcare job.
- Ask whether the record exists in ImmuNet or only with a provider.
- Do not wait until the last day before a school or travel deadline.
Maryland Medicaid, Medical Assistance and HealthChoice help
Maryland Medicaid is also called Medical Assistance. MDH describes Medicaid as free or low-cost health insurance for eligible low-income adults, children, pregnant women, elderly adults and people with disabilities.
Maryland Health Connection is where users enroll in Medicaid. HealthChoice is Maryland Medicaid’s managed care program. For HealthChoice questions, MDH lists the helpline at 800-284-4510.
Maryland Health Connection phone, enrollment and coverage help
Maryland Health Connection is Maryland’s official health insurance marketplace. It helps users apply for Medicaid, enroll in private plans, compare coverage and get local help.
The consumer support phone number is 1-855-642-8572. Official Maryland Health Connection pages also point users to free local help and enrollment support.
Apply or update coverage
Use Maryland Health Connection online, by phone, through local help or through the mobile app when available.
Prepare documents
Have household members, income, address, immigration/citizenship information where relevant, existing coverage and notices ready.
Respond to notices
If Maryland Health Connection or Medicaid asks for proof, upload or submit documents by the deadline.
Maryland WIC appointments, local agencies, benefits and fraud reporting
Maryland WIC says users should contact the local agency where they live to apply for benefits and make an appointment. The state WIC main office is at 201 W. Preston Street, 1st Floor, Baltimore, MD 21201.
For program questions and fraud reports, Maryland WIC lists the toll-free hotline at 1-800-242-4942.
Before your Maryland WIC appointment
- Confirm the local WIC agency and appointment format.
- Ask what proof of identity, address and income is required.
- Ask about eWIC card, benefit balance, approved foods and breastfeeding support.
- Use the official complaint/fraud route for suspected misuse of benefits.
Maryland 988, mental health, substance use and Behavioral Health Administration
Maryland’s 988 page says people can call, text or chat 988 to talk with a specialist and connect with services for mental health or substance use emergencies.
Use 988 for mental health crisis, substance use crisis, emotional distress or concern about someone who may need crisis support. Call 911 if there is immediate danger or urgent medical need.
Maryland health professional license lookup, board contact and renewal help
Many users search MDH because they need to verify a nurse, physician, pharmacist, therapist, counselor, long-term care administrator or other licensed professional. MDH and its health occupation boards use separate board-specific pages and lookup tools.
Do not use the wrong board. Nursing lookup, physician profile, pharmacy board, CDS search, social work, counseling and long-term care administrator verification are different routes.
Maryland healthcare facility complaints, OHCQ and billing complaint routing
The Office of Health Care Quality monitors quality of care in Maryland healthcare facilities and community-based programs. OHCQ complaint routing depends on the facility type.
For billing complaints, Maryland’s OHCQ page points users to the Maryland Attorney General’s Consumer Protection Division. For immediate danger, call 911 first.
| Complaint type | Possible route | Prepare before filing |
|---|---|---|
| Hospital or facility care complaint | OHCQ complaint page or program unit. | Facility name, address, patient/resident, date, what happened and supporting documents. |
| Nursing home complaint | OHCQ long-term care route or nursing home complaint unit. | Resident name, safety issue, dates, staff notified, photos/documents if relevant. |
| Home health agency complaint | Home Health Hotline route where applicable. | Agency name, missed/poor service, dates, care plan and safety impact. |
| Billing complaint | Maryland Attorney General Consumer Protection Division may be more appropriate. | Bill, provider, insurer response, dates, notices and amount disputed. |
Maryland Department of Health Public Information Act, HIPAA and records requests
Maryland’s Public Information Act route is for MDH public records requests. It is not the same as asking a hospital for your personal medical chart or asking Vital Records for a birth certificate.
MDH’s PIA page says mailed requests may be sent to: Maryland Department of Health, Attn: Public Information, 201 W. Preston St., Suite 507G, Baltimore, MD 21201.
What Maryland Department of Health may not handle
Several health-related searches belong to another agency, provider, insurer, court or federal program.
