Most people get a physical therapy referral from their primary care doctor, but physicians are far from the only providers who can send you. Depending on your state and insurance plan, you may not need a referral at all.
Providers Who Can Refer You
Any licensed physician, whether an MD or DO, can write a referral or prescription for physical therapy. This includes your primary care doctor, an orthopedic surgeon, a neurologist, a sports medicine physician, or any other specialist. If a doctor identifies a condition that physical therapy could help, they have the authority to refer you regardless of their specialty.
Beyond physicians, several other licensed practitioners can refer you to physical therapy. Nurse practitioners (NPs) and physician assistants (PAs) regularly write physical therapy referrals as part of their scope of practice. In many states, NPs practice independently without physician oversight, which means they can evaluate you, diagnose a condition, and send you to physical therapy on their own authority. PAs typically work as part of a physician-supervised team but still write referrals routinely.
Dentists and podiatrists can also prescribe physical therapy for conditions within their scope. A dentist might refer you for jaw-related physical therapy (such as treatment for TMJ disorders), while a podiatrist could refer you for foot, ankle, or gait-related rehabilitation. In programs like Medi-Cal, physical therapy is specifically covered when ordered by a physician, dentist, or podiatrist.
You May Not Need a Referral at All
All 50 states, the District of Columbia, and the U.S. Virgin Islands now allow some form of direct access to physical therapy. This means you can walk into a physical therapy clinic, get evaluated, and start treatment without a referral from anyone. The American Physical Therapy Association confirms that every U.S. jurisdiction offers either provisional or unrestricted direct access for evaluation and treatment.
The specifics vary by state. Twenty-seven states impose a visit or time limit on how long you can see a physical therapist before a physician needs to get involved. Some states cap direct access at a set number of visits or days, after which the therapist must obtain a referral for continued treatment. Eight states limit direct access to certain patient populations or circumstances, six require a referral for specific treatment interventions, and nine require the physical therapist to hold certain qualifications (such as additional years of experience or an advanced degree) before treating without a referral. Thirteen states explicitly allow physical therapists to provide fitness and wellness services with no referral requirement.
Even in states with unrestricted direct access, your physical therapist will typically develop a plan of care and may coordinate with a physician, especially for complex or ongoing conditions.
What Your Insurance Actually Requires
State law and insurance coverage are two different things, and this is where many people get tripped up. Your state might allow direct access, but your insurance plan can still require a referral before it will pay for treatment.
The general pattern: PPO plans from major insurers like Blue Cross Blue Shield, Cigna, and UnitedHealthcare typically cover physical therapy under direct access without a referral. HMO plans almost always require a referral for the insurance company to pay. A physical therapist can legally treat you without a prescription in a direct access state, but if you have an HMO plan, the therapist will likely be denied payment without one. That leaves you responsible for the bill.
Before booking an appointment without a referral, call your insurance company and ask two questions: does your plan require a referral for physical therapy, and does it require prior authorization? These are separate requirements. Some plans need both.
How Medicare Handles It
Medicare allows you to see a physical therapist under direct access for an initial evaluation and to begin treatment. However, the physical therapist must establish a written plan of care, and a physician or non-physician practitioner (such as an NP or PA) must sign off on that plan within 30 days of your first treatment session. Without that signature, Medicare won’t continue covering your visits.
The certifying provider must also recertify the plan at least every 90 days or whenever a significant change is made to your treatment. If your therapist calls your doctor’s office to get a plan of care signed, this is the requirement they’re fulfilling. Verbal orders are acceptable initially, but the physician or NP must provide a written signature within 14 days.
Workers’ Compensation Cases
Workplace injuries follow a different path. If your employer issues a CA-16 authorization form (used in the federal workers’ compensation system), no separate authorization is needed for physical therapy related to the work injury. The form itself serves as your ticket to treatment, covering office visits, imaging, physical therapy, and emergency services.
Without a CA-16, physical therapy authorization can only be requested once a claim number has been established. More intensive procedures may require additional levels of authorization. The referring provider in workers’ comp cases is typically the treating physician assigned to your claim. Your employer’s occupational health team, which might include certified occupational health nurses, often coordinates the referral process but generally does so in consultation with a physician rather than independently.
Occupational Health and Employer Clinics
Some larger employers have on-site health clinics staffed by various levels of healthcare providers. Who can refer you from these settings depends on the provider’s credentials. If the clinic has a physician, NP, or PA on staff, they can refer you to physical therapy just as they would in any other clinical setting. Certified occupational health nurses can provide direct care and serve as case managers, but their referral authority depends on state nursing scope-of-practice laws.
First aid providers at a workplace, such as employees trained in basic first aid, do not have the qualifications to make referral decisions. OSHA guidelines are clear that these providers should not create barriers to workers seeing a qualified healthcare professional for diagnosis and treatment. If you’re injured at work and someone without medical credentials tells you that you don’t need physical therapy, you have the right to seek evaluation from a licensed provider who can make that determination.
