Alcohol & Drug Rehabs in Gaithersburg, Maryland

Every rehab center in the Gaithersburg directory is a licensed or accredited provider, and listings are organized to help you compare real options rather than to promote one facility over another. We prioritize programs licensed by the Maryland Behavioral Health Administration (BHA) and independently accredited by the Joint Commission or CARF, and we label any sponsored placement clearly so you always know what you are looking at.

Listing details reflect the levels of care, specialty tracks, and payment types each facility reports, drawn from public licensing records and facility information. Because openings and insurance participation change, confirm current availability and program specifics directly with a center when you reach out. The aim is to give you an accurate starting point for finding care close to home.

Gaithersburg is one of Montgomery County’s largest cities, an up-county hub along the I-270 technology corridor in the Washington, D.C. suburbs, with a solid base of addiction treatment. The area has 13 rehab centers offering detox, inpatient, and outpatient care, and you can compare every nearby option through the Maryland rehab directory.

Montgomery County’s Department of Health and Human Services runs Behavioral Health and Crisis Services, including a 24/7 Crisis Center in nearby Rockville and an ACCESS line that matches residents to treatment. Adventist HealthCare Shady Grove Medical Center anchors hospital-based care nearby, and the county’s Pick Up the Pieces campaign helps people navigate options. Maryland Medicaid coverage for addiction care runs through the Public Behavioral Health System.

As in much of the D.C. suburbs, fentanyl drives most local overdose deaths, and Montgomery County pairs free naloxone and test strips with a broad treatment network. Statewide, Maryland overdose deaths have fallen for four straight years to a 10-year low.

The cost of rehab in Gaithersburg depends on the level of care, program length, and whether you use insurance. Maryland sits near the middle of the regional range, with a statewide residential average of roughly $56,783 without insurance, though most people pay a fraction of that once insurance benefits are applied. The figures below reflect Maryland averages by care type.

Actual costs vary with setting, amenities, and length of stay. Outpatient programs cost far less than residential care and are the most common local format, while medical detox and inpatient stays carry the highest price tags. Because Gaithersburg sits in the higher-cost D.C. suburbs, private-pay rates can run above the state average, though Maryland Medicaid and public behavioral health funding anchor affordability.

Treatment setting: inpatient and residential care cost more than outpatient.

Program length: 30, 60, and 90-day programs scale in price.

Level of care: medical detox and 24-hour supervision raise costs.

Insurance status: in-network coverage and Medicaid reduce out-of-pocket cost.

Region: D.C. suburban private-pay rates run higher than rural Maryland.

Across the 13 rehab centers serving Gaithersburg, most accept self-payment and private insurance, and many work with Maryland Medicaid, financial assistance, and Medicare. The counts below show how many local facilities report accepting each payment type.

11 accept self-payment or cash

9 accept private health insurance

7 accept Maryland Medicaid

4 offer financial assistance

3 accept Medicare

3 offer sliding-scale fees

3 offer financing

2 accept TRICARE

Which option makes the most sense depends on your coverage and income. The subsections below outline how the main payment paths work for Gaithersburg residents.

Maryland Medicaid

Maryland Medicaid covers the full continuum of substance use care through the Public Behavioral Health System, from detox to outpatient counseling and medication for addiction treatment, including all three FDA-approved opioid use disorder medications. Specialty behavioral health benefits are administered by Carelon Behavioral Health for HealthChoice members. Seven Gaithersburg facilities report accepting Maryland Medicaid, and the county ACCESS line can help match you to one.

Medicare

Medicare covers substance use treatment that is medically necessary, including inpatient care under Part A and outpatient services and counseling under Part B, with Medicare Advantage plans offering the same benefits. Three Gaithersburg area centers accept Medicare.

Military and TRICARE

Veterans and active-duty families have several routes to care. Two area facilities accept TRICARE, and the VA Maryland Health Care System and the nearby Washington, D.C. VA Medical Center coordinate veteran services. See more rehab resources for veterans and military families.

Insurance and Private Pay

Most Gaithersburg centers accept private insurance or self-payment, and Maryland parity laws require commercial plans to cover substance use treatment. Coverage varies by plan and network status, so verify benefits before you commit. Major carriers active in Maryland include:

• CareFirst BlueCross BlueShield
• UnitedHealthcare
• Kaiser Permanente
• Cigna
• Aetna

Other Low-Cost Options

For those without full coverage, four Gaithersburg centers offer financial assistance, three offer sliding-scale fees, and three offer financing. Public behavioral health funding serves residents regardless of ability to pay, and treatment scholarships can help close the gap.

Accreditation

Accreditation signals that a program meets independent quality standards. Among Gaithersburg area facilities, four hold CARF accreditation and three hold Joint Commission accreditation, a strong share. Accreditation is separate from BHA licensing, which every legitimate Maryland substance use provider must maintain.

Gaithersburg offers care across the continuum, with 3 detox programs, 5 inpatient programs, and 13 outpatient clinics reported locally, plus partial hospitalization and intensive outpatient. Nearly every facility also treats co-occurring mental health conditions.

3 medical detox facilities

5 inpatient rehab programs

2 partial hospitalization programs

2 intensive outpatient programs

13 standard outpatient clinics

14 dual diagnosis programs

Medical detox provides 24-hour supervision to manage withdrawal safely and is the usual first step for opioid or alcohol dependence. Three area programs offer medically supervised detox.

Inpatient and residential rehab provides structured, live-in treatment. Five local inpatient rehab programs serve people who need to step away from daily triggers to focus on early recovery.

Partial hospitalization and intensive outpatient deliver structured daytime treatment while a person lives at home. Area programs offer PHP and IOP as a step up from standard outpatient or a step down from residential care.

Outpatient treatment lets people live at home while attending scheduled sessions, and it is the most common local format, with 13 clinics reported. It suits people balancing work or family.

Dual diagnosis care treats addiction alongside conditions like anxiety disorders or depression. Reporting facilities across the local directory address co-occurring disorders, which matters given how often mental health and substance use overlap.

Many Gaithersburg facilities tailor treatment to specific groups and substances. The counts below reflect programs that report each specialty focus.

11 young adult programs

10 women’s programs

10 men’s programs

8 alcohol rehab programs

6 opioid rehab programs

4 programs for older adults

2 LGBTQ+ friendly programs

2 veterans and military programs

Programs for young adults are the most widely reported specialty locally, and eight programs address alcohol use disorder while six treat opioid use disorder. Facilities also serve women, men, older adults, and veterans, and offer LGBTQ+ affirming addiction care.

Cost should not keep anyone from help. Gaithersburg residents can reach crisis support, treatment access lines, and harm-reduction resources at no charge, including crisis and suicide-prevention support around the clock.

Maryland recorded one of the nation’s steepest declines in overdose deaths, and overdose data show a fourth straight year of improvement driven by naloxone saturation and expanded medication for opioid use disorder.
