Whether Medicaid requires referrals depends on how your coverage is delivered. If you’re in a Medicaid managed care plan — and about 74 percent of enrollees nationally are — you almost always need a referral from your primary care provider before seeing a specialist.1MACPAC. Percentage of Medicaid Enrollees in Managed Care by State and Eligibility Group FY 2023 If you’re in fee-for-service Medicaid, you generally don’t. And regardless of which model covers you, federal law protects several categories of care that never require a referral.
First, Figure Out Which Type of Medicaid You Have
Medicaid comes in two basic flavors, and the referral question turns on which one you’re in.
Under fee-for-service Medicaid, the state pays providers directly for each service. You generally pick your own doctors and can see a specialist without a referral, though some states still require prior approval for expensive procedures. Only a handful of states still run a purely fee-for-service system.
Under managed care, the state pays a private health plan a fixed monthly amount per enrollee, and that plan builds a network, pays claims, and coordinates your care. You choose (or are assigned) a primary care provider who acts as a gatekeeper: your PCP decides when a specialist visit is warranted and sends the referral.2MACPAC. Provider Payment and Delivery Systems In some states, more than 90 percent of Medicaid enrollees are in comprehensive managed care.
Not sure which you have? Your Medicaid card or welcome packet will name your managed care plan. No plan name usually means fee-for-service.
What Typically Needs a Referral in Managed Care
In a managed care plan, expect to need a referral for most specialist visits — cardiologists, dermatologists, orthopedic surgeons, and the like. Skipping that step can leave you responsible for the entire bill, because the plan may refuse to pay for services delivered without an authorized referral.
Beyond specialist appointments, a referral or plan approval is commonly required for:
- Diagnostic imaging and advanced lab work, such as MRIs and CT scans.
- Physical, occupational, and speech therapy, usually with the referral specifying type and duration.
- Non-emergency hospital admissions and planned surgeries.
- Durable medical equipment such as wheelchairs or CPAP machines, which typically need both a referral and a prescription.
It’s worth knowing that a referral and a prior authorization are two different steps. A referral is your PCP directing you to a specialist. Prior authorization is the plan itself approving coverage for a specific treatment, procedure, or medication, often after you’ve already seen the specialist. You may need both for the same episode of care: a referral to see the orthopedic surgeon, then prior authorization before that surgeon can schedule your knee surgery.
How strict any of this is depends on the plan. Two managed care organizations in the same state can handle referrals differently. Your member handbook lists exactly which services need a referral and which need prior authorization.
Care You Can Get Without a Referral
Federal law and standard managed care contracts protect several categories of care from the referral requirement. These exceptions exist because certain situations are too urgent, too routine, or too sensitive to route through a gatekeeper.
Emergency Care
No Medicaid plan can require a referral or prior authorization for emergency services. If you believe you’re having a medical emergency, go directly to the nearest emergency room. The plan must cover emergency care at any hospital, including out-of-network hospitals, and cannot penalize you for not getting approval first.
Routine Visits With Your PCP
You don’t need a referral to see your own PCP. Annual physicals, well-child visits, immunizations, and routine screenings are all accessible directly, with no additional approval step.
Women’s Health Services
Federal regulations require every Medicaid managed care plan to give female enrollees direct access to a women’s health specialist for routine and preventive care, even if that specialist isn’t the enrollee’s PCP.3eCFR. 42 CFR 438.206 – Availability of Services You can see an OB/GYN for annual exams, prenatal care, and other routine needs without a PCP referral.
Family Planning
Medicaid beneficiaries have a federally protected right to receive family planning services — contraception counseling, birth control, STI testing, and related care — from any qualified provider, in-network or not. Managed care plans cannot require a referral for family planning and cannot restrict you to in-network providers for these services.
Behavioral Health
Access to mental health and substance use treatment without a referral varies by state and plan. Some states require direct access to behavioral health providers; others still route these visits through the PCP. If you’re in crisis, most plans treat that as an emergency and won’t require a referral. Check your member handbook, because state rules diverge significantly here.
Extra Protections for Children Under EPSDT
If you’re a parent navigating Medicaid for a child under 21, the rules tilt in your favor. The Early and Periodic Screening, Diagnostic, and Treatment benefit, known as EPSDT, is a federal entitlement that sets a higher coverage standard for children than for adults. States must cover any medically necessary service to correct or treat a condition discovered during screening, even if that service isn’t normally covered under the state’s adult Medicaid plan.4Medicaid.gov. SHO 24-005 – Best Practices for Adhering to EPSDT Requirements
Your child’s plan may still require a referral to see a specialist, but the plan cannot use prior authorization rules or medical necessity criteria to deny a service that EPSDT requires. If a screening identifies a condition, the state must arrange diagnostic follow-up and treatment, including specialist referrals. That’s useful leverage if a plan pushes back on a referral for your child.
If Your Referral Is Denied
A denied referral isn’t the end of the road. Managed care plans must follow federal rules that give you real options.
Appeal to the plan first. A denial or limitation of a referral is called an adverse benefit determination. You have 60 calendar days from the date on the denial notice to file an appeal with your managed care plan. The plan must resolve a standard appeal within 30 calendar days. If your health is at immediate risk, you can request an expedited appeal, which the plan must resolve within 72 hours.5eCFR. 42 CFR Part 438 Subpart F – Grievance and Appeal System If the denied service is one you were already receiving, you may be able to keep getting it during the appeal, but you generally need to file before the denial takes effect.
Then request a state fair hearing. If the plan upholds its denial, you can take the dispute to the state. Federal law requires every state Medicaid program to offer a fair hearing to anyone whose claim is denied or not acted on promptly.6Office of the Law Revision Counsel. 42 USC 1396a – State Plans for Medical Assistance The hearing is conducted by an independent state officer, not by the plan that denied you, and the denial notice must explain how to request one.
Ask for a second opinion, or change your PCP. Sometimes the problem isn’t the plan but a PCP who won’t initiate the referral. Federal rules guarantee you a second opinion from a qualified in-network provider at no extra cost.7eCFR. 42 CFR Part 438 – Managed Care You can also change your primary care provider by calling member services. Most plans allow at least one or two changes per year without needing a reason, and changes with cause can happen at any time.
One more scenario worth flagging: if no in-network specialist can provide the care you need, your plan cannot simply deny the referral. It must cover the service out-of-network, and your cost-sharing cannot be higher than it would be in-network.7eCFR. 42 CFR Part 438 – Managed Care This comes up most often in rural areas or for rare conditions.
Check Your Handbook Before You Assume
Federal law sets the floor, but states and individual plans build on top of it. Two people with Medicaid in different states — or in different managed care plans within the same state — can face different referral requirements for the same type of visit.
Your most reliable source of plan-specific information is your member handbook. It spells out which services need a referral, which need prior authorization, which providers are in-network, and how to file an appeal. If you’ve lost your copy, call the member services number on your Medicaid card or download it from your plan’s website. When you’re unsure whether a particular visit needs a referral, call before you go. A two-minute phone call can prevent an unexpected bill.
