Cold laser therapy can be administered by physicians, chiropractors, physical therapists, and occupational therapists, among other licensed healthcare providers. The specific professionals allowed to perform or oversee treatment vary by state, and in some cases, trained support staff can deliver it under direct supervision. Lower-power devices are also available for home use without a prescription.
Licensed Professionals Who Perform Cold Laser Therapy
The core group of professionals who administer cold laser therapy in clinical settings includes physicians, chiropractors, physical therapists, and occupational therapists. These providers typically use the therapy in an office or outpatient setting for pain management, tissue healing, and inflammation reduction. Each of these professionals operates within their own scope of practice, meaning a chiropractor might use it for back pain while a physical therapist applies it as part of a rehabilitation program after surgery.
Beyond these four, other licensed providers can also be involved. Physician assistants, nurse practitioners, and registered nurses fall into a category of higher-level nonphysician providers who may deliver laser treatment, provided they have appropriate training. Dentists and podiatrists sometimes use cold laser therapy within their specialties as well, though this depends on state licensing rules.
When Support Staff Can Deliver Treatment
In many states, lower-level staff members, including licensed practical nurses, medical assistants, and surgical assistants, can operate cold laser devices. The key requirement is supervision by a laser-trained physician or other qualifying provider. Published clinical guidelines recommend specific conditions for this arrangement: no more than two nonphysician providers should be supervised by a single laser-trained physician at one time, and the supervising physician should be on-site during at least 50% of the time laser services are being delivered. When the supervising physician is not physically present, another laser-trained physician must be available on-site or reachable by phone and able to come in if a patient issue arises.
Regardless of their training level, all nonphysician providers are expected to complete safety training, follow diagnosis and treatment protocols created by the supervising physician, and report any unusual patient outcomes for review. The independent delivery of laser treatment by someone without a medical license is broadly considered unauthorized practice of medicine.
State-by-State Differences in Scope of Practice
There is no single federal law that dictates exactly who can use a cold laser on a patient. Instead, each state’s medical board, physical therapy board, and chiropractic board sets its own scope-of-practice rules. Some states are more permissive, allowing a broader range of trained professionals to administer treatment. Others require specific licensure categories.
Georgia, for example, created a dedicated licensing path for cosmetic laser practitioners with two tiers: assistant laser practitioner and senior laser practitioner. While this applies to cosmetic laser use rather than cold laser therapy for pain, it illustrates how granular state regulations can get. If you work in a clinic or are considering opening a practice that includes cold laser therapy, checking your state board’s current rules is essential before purchasing equipment or delegating treatment to staff.
How the FDA Classifies Cold Laser Devices
The FDA classifies low-level laser systems as Class II medical devices with special controls. This means they carry moderate risk and require specific labeling, safety testing, and performance standards before they can be marketed. Importantly, many cold laser devices are classified as prescription devices. Under federal regulations, prescription devices are exempt from needing instructions for lay use but must include adequate information for practitioner use, covering indications, treatment methods, frequency, duration, and any hazards or contraindications.
In practical terms, the prescription label means the device is intended to be used by or on the order of a licensed healthcare provider. This doesn’t necessarily prevent someone from purchasing a device for home use (more on that below), but it does shape how manufacturers market and distribute higher-powered units.
Safety Requirements in Clinical Settings
Clinics using Class 3B or Class 4 lasers must follow safety standards set by the American National Standards Institute (ANSI). These include designating a Laser Safety Officer, providing wavelength-specific protective eyewear for everyone in the treatment area, and posting warning signs on all doors entering the laser treatment zone. Signs should be removed or covered when the laser is not in use.
Staff training is a formal requirement, not a suggestion. OSHA guidelines specify that laser safety training must be provided to laser safety officers, device users, technical support staff, and nurses or allied health personnel who work in the presence of the laser. All training activities must be documented and kept on file. Clinics are also required to ensure proper alignment and calibration of the laser system before each use, and maintenance can only be performed by facility-authorized technicians trained in laser service.
Skin protection is recommended when repeated exposures are expected near the maximum permissible exposure limits. For procedures that generate airborne contaminants, local exhaust ventilation or smoke evacuation systems with in-line filters are required.
Home Use Devices and Self-Treatment
You don’t necessarily need a clinician to receive cold laser therapy. Several FDA-cleared devices are sold directly to consumers for home use. The rules depend on the laser’s power class. Class 1M and Class 3B devices (up to 500 milliwatts) are available without a prescription. Class 4 devices, which range from 500 milliwatts to over 60 watts, require a doctor’s prescription, though obtaining one from a physician, chiropractor, or other licensed provider is generally straightforward.
Home devices typically come with safety glasses, treatment protocols, and training materials. The safety precautions mirror those in clinical settings: always wear protective eyewear with Class 3B and Class 4 devices, as they can damage the retina. Cold laser therapy should not be applied over known cancerous tumors, directly over the thyroid gland, over a pregnant uterus, or over implanted electronic devices like pacemakers. It is safe to use over metal implants, pins, plates, and stitches.
Class 1M devices use super-pulsed technology that makes them eye-safe by design, so goggles are technically not required, though they’re usually included anyway. If you’re considering a home device, the power class is the single most important factor in determining what precautions you need to take and whether you’ll need a prescription to buy it.
