Medicaid covers a wide range of health services, from routine doctor visits to long-term nursing home care, but exactly what you get depends on where you live. The federal government requires every state to provide a core set of benefits, while giving states the option to add dozens more. Beyond these medical benefits, Medicaid also operates specialized programs for children, seniors, people with disabilities, and individuals transitioning out of incarceration.
Benefits Every State Must Provide
Federal law mandates that all state Medicaid programs cover a baseline set of services. These include inpatient and outpatient hospital care, physician services, lab work and X-rays, nursing facility care, and home health services. Family planning, nurse midwife services, and certified nurse practitioner care are also guaranteed. Every state must provide transportation to medical appointments, a benefit many enrollees don’t realize exists.
Medication-assisted treatment for substance use disorders is mandatory as well. So is tobacco cessation counseling for pregnant women and hospice-concurrent care for children (meaning a child can receive hospice services while still getting curative treatment). States also must cover routine costs for enrollees participating in qualifying clinical trials.
Optional Benefits That Vary by State
States can choose to add optional benefits through a formal plan amendment. The most notable optional services include prescription drugs, dental care, vision care (including eyeglasses), physical therapy, occupational therapy, and speech therapy. While nearly every state covers prescription drugs in practice, it is technically not a federally required benefit.
Other optional categories include:
- Personal care services: Help with daily activities like bathing, dressing, and meal preparation
- Private duty nursing: Skilled nursing care provided in the home
- Prosthetics and dentures
- Case management: Coordination of medical and social services
- Hospice care for adults
- Inpatient psychiatric services for people under 21
- Intermediate care facilities for individuals with intellectual disabilities
This is why two people on Medicaid in different states can have very different coverage. If you’re trying to figure out whether a specific service is covered, your state Medicaid agency’s website or a call to their helpline is the most reliable source.
Children’s Coverage: EPSDT and CHIP
Children on Medicaid get the most comprehensive package of any group, thanks to a program called Early and Periodic Screening, Diagnostic, and Treatment (EPSDT). This benefit is mandatory for everyone under 21 and goes well beyond what adult Medicaid typically covers. States must provide any service that is medically necessary to treat, correct, or reduce a health condition found during screening, even if that service isn’t part of the state’s regular Medicaid plan.
EPSDT includes vision screening with eyeglasses when needed, hearing screening with hearing aids, and dental care covering pain relief, infection treatment, tooth restoration, and medically necessary orthodontics. All age-appropriate vaccines recommended by federal guidelines are covered. When a screening identifies a problem, the state must provide diagnostic follow-up without delay and then pay for whatever treatment is needed.
The Children’s Health Insurance Program (CHIP) extends coverage to kids in families who earn too much to qualify for Medicaid but not enough to afford private insurance. States can run CHIP as an expansion of their Medicaid program, as a separate program, or as a combination. In separate CHIP programs, states have more flexibility to cap enrollment, impose waiting periods, and charge premiums or copays. Income limits for children generally reach higher than for adults. In New York, for example, children ages 1 through 18 qualify at household incomes up to 154% of the federal poverty level, while pregnant women and infants qualify up to 223%.
Home and Community-Based Services
One of the most significant Medicaid programs is Home and Community-Based Services (HCBS), delivered through special waivers that let states pay for long-term care outside of a nursing home. These waivers exist because many people who need ongoing support, whether due to aging, physical disability, or intellectual disability, prefer to receive that care at home or in a community setting rather than in an institution.
To qualify, you generally need to demonstrate a level of care that would otherwise make you eligible for institutional placement. The specific services offered vary by state and by waiver but can include personal care attendants, home modifications, adult day programs, respite care for family caregivers, and assistive technology. States can also design services specifically aimed at helping people transition out of nursing homes and back into the community. These waivers are a lifeline for hundreds of thousands of families managing complex care needs.
Programs for Seniors
The Program of All-Inclusive Care for the Elderly (PACE) is a specialized Medicaid option for people 55 and older who need a nursing-home level of care but want to keep living at home. PACE organizations become the single source of both Medicare and Medicaid benefits for participants, coordinating everything through a team of health professionals.
To join PACE, you must be 55 or older, live in the service area of a PACE organization, be certified as eligible for nursing home care, and be able to live safely in the community at the time of enrollment. The model is designed so that providers can deliver whatever services a participant actually needs rather than being limited to what fee-for-service billing would cover. Participants can leave the program at any time. PACE is available as a state option, so not every state offers it, and service areas within participating states may be limited.
Coverage for People on Both Medicare and Medicaid
About 12 million Americans qualify for both Medicare and Medicaid, a group known as “dual eligibles.” Navigating two separate insurance programs is complicated, so Dual Eligible Special Needs Plans (D-SNPs) exist to coordinate benefits in a single plan. D-SNPs are Medicare Advantage plans specifically designed for this population. Some D-SNPs offer zero-dollar cost sharing for Medicare services, which can significantly reduce out-of-pocket expenses. Depending on the state and the individual’s specific eligibility category, Medicaid may cover certain Medicare costs like premiums, deductibles, and copays.
State Demonstration Waivers
Section 1115 waivers let states test new approaches that go beyond traditional Medicaid. These have become a major tool for expanding what Medicaid can do, and several recent initiatives have pushed the boundaries of health coverage into areas once considered outside its scope.
One significant development is coverage for health-related social needs. Starting in 2022, the federal government began encouraging states to use Medicaid funds to address housing instability, homelessness, and food insecurity, recognizing that these factors directly affect health outcomes. Multiple states now have approved waivers covering services like temporary housing assistance, nutrition counseling, and help with utility costs.
Another major shift involves pre-release coverage for incarcerated individuals. Nineteen states received approval to provide Medicaid-covered services to people in the period before their release from jail or prison. The goal is to ensure continuity of care, particularly for behavioral health and chronic conditions, during the transition back into the community. Federal law normally prohibits Medicaid from paying for services during incarceration, so these waivers represent a significant policy change.
Some states have also used 1115 waivers to establish multi-year continuous eligibility for children, preventing coverage gaps caused by the annual renewal process.
The Spend-Down Pathway
If your income is too high for standard Medicaid but your medical bills are overwhelming, you may still qualify through what’s called a “spend down.” This works similarly to a deductible: you accumulate medical expenses you’re responsible for paying until the total reaches a threshold amount, and Medicaid then kicks in to cover the rest for that eligibility period.
You can count medical bills from the three months before your application date, as long as you still owed money on them at that time. Both paid and unpaid bills count, but you can’t use bills that were covered by insurance or paid by someone else. Once your spend-down amount is met, Medicaid covers the remaining costs for services that fall within Medicaid’s benefit categories. This pathway exists in states that operate a “medically needy” program, and not all states do.
Retroactive Coverage
Medicaid can cover medical bills you received before you even applied. If you would have been eligible during the three months before your application month, benefits can be applied retroactively to cover expenses from that period. This is a federal rule, not a state option, and it exists to protect people who were eligible but didn’t know it or weren’t able to apply right away. If you have unpaid medical bills from recent months, applying for Medicaid now could help cover them.
