Dry needling is illegal in California for most practitioners because state law defines any insertion of needles to treat pain or muscle function as acupuncture, and only a narrow group of licensed professionals is authorized to perform it. Physical therapists, who perform dry needling in most other states, are not on that list. If you want needle-based trigger-point therapy in California, you need to see a licensed acupuncturist or a physician.
The Statute That Sweeps Dry Needling In
The restriction comes from a single definition. California Business and Professions Code Section 4927 defines acupuncture as “the stimulation of a certain point or points on or near the surface of the body by the insertion of needles to prevent or modify the perception of pain or to normalize physiological functions.”1California Legislative Information. California Code, BPC 4927
That language is broad. Dry needling targets myofascial trigger points based on Western anatomy rather than the meridian points used in traditional Chinese medicine, and practitioners elsewhere treat the two techniques as distinct. California regulators do not. Because dry needling involves inserting a needle through the skin to modify pain or normalize how muscles function, it falls inside the statutory definition of acupuncture. The theoretical framework behind the needle does not change the legal classification.
Who Can Legally Perform Dry Needling in California
Because needle insertion for pain or muscle treatment counts as acupuncture, only practitioners whose license covers that procedure can perform it. In practice, three groups qualify:
- Licensed acupuncturists, who hold a license under the Acupuncture Licensure Act and are regulated by the California Acupuncture Board. California acupuncture programs require thousands of hours of education, including extensive needle technique practice.2Justia. California Business and Professions Code Article 1 – Administration and General Provisions
- Physicians (MDs and DOs), whose broad scope under the Medical Practice Act includes acupuncture and related needling techniques without a separate acupuncture license.
- Dentists, within the limited scope of oral and facial treatment. This rarely comes up in the dry needling conversation.
If you are a patient looking for trigger-point needling, your realistic options are a licensed acupuncturist or a physician. Many acupuncturists incorporate myofascial trigger-point techniques alongside traditional methods, so ask about their approach when you schedule.
Why Physical Therapists Can’t Do It
The Physical Therapy Practice Act, in Article 2 of the Business and Professions Code, lists what California physical therapists are authorized to do. Needle insertion is not on that list. A 2026 background paper prepared for the California Senate’s oversight hearing of the Physical Therapy Board stated it directly: “The Acupuncture Practice Act prohibits ‘the insertion of needles to prevent or modify the perception of pain or to normalize physiological functions’ unless expressly authorized elsewhere. The Physical Therapy Practice Act does not contain that authorization.”3California Senate. Physical Therapy Board of California Background Paper 2026
This puts California at odds with most of the country. The American Physical Therapy Association reports that the majority of states specifically allow physical therapists to perform dry needling, often with additional continuing-education requirements. California and a small number of other states either prohibit it outright or have not addressed it, which amounts to the same thing. The Physical Therapy Board of California has consistently read its own practice act as excluding dry needling, and no court has overturned that reading.
What Happens if a PT Does It Anyway
A physical therapist who performs dry needling in California is practicing outside the authorized scope. The consequences can run on two tracks.
At the administrative level, the Physical Therapy Board can take disciplinary action against the license, ranging from a formal reprimand to suspension or revocation. At the criminal level, California Business and Professions Code Section 2052 makes it a crime to practice medicine or a regulated healing art without proper authorization. The offense is a wobbler, meaning prosecutors can charge it as either a misdemeanor or a felony. A misdemeanor conviction carries up to 364 days in county jail and a fine up to $1,000. A felony conviction carries 16 months to three years in state prison and a fine up to $10,000.
Criminal prosecution of a licensed PT for dry needling would be unusual in practice. License discipline is the realistic risk. A complaint from a patient, a competing practitioner, or an insurance company can trigger a board investigation.
The Safety Concerns Behind the Rule
The restriction leans heavily on patient-safety arguments. Most dry needling side effects are mild: bleeding, bruising, and post-treatment soreness. Serious complications do occur, particularly when needles go in near the lungs, major blood vessels, or nerves.4PMC. Pneumothorax as a Complication of Dry Needling Technique
Pneumothorax, a collapsed or partially collapsed lung from a needle penetrating the chest wall, is the most-discussed serious risk. A 2024 case series documented four patients who developed pneumothorax after dry needling sessions between September 2022 and December 2023.4PMC. Pneumothorax as a Complication of Dry Needling Technique Other rare but documented adverse events include nerve injury, significant bleeding, infection, and cardiac tamponade. Needling in the neck, shoulder, and upper back carries the highest risk because of the proximity to the lung apex.
Dry needling is also not appropriate for everyone. Published clinical guidelines identify several groups who should not receive it, including children under 12, people with needle phobia, patients with compromised immune systems, those with vascular disease, and women in their first trimester of pregnancy.5PMC.

Could the Law Change?
Advocates for expanding physical therapy scope have tried before. Bills aimed at authorizing dry needling for physical therapists have either stalled in committee or failed to gain enough support to reach the governor’s desk. California’s acupuncture profession is well-organized and treats any expansion of needling privileges as a direct threat to patient safety and professional boundaries.
The fight is not finished. At the Physical Therapy Board’s December 2024 public meeting, stakeholders expressed interest in modernizing the Physical Therapy Practice Act and were seeking a legislative author to introduce a bill in 2026.3California Senate. Physical Therapy Board of California Background Paper 2026 The Senate oversight committee has asked the Board to report on any discussions it has held about dry needling and whether it has identified gaps in care or patient safety concerns. Whether a new bill can overcome the opposition that has defeated past attempts is an open question.
Insurance and Cost in California
Dry needling has its own billing codes, CPT 20560 (one or two muscles) and CPT 20561 (three or more muscles), but many insurers will not pay for it.6CMS. National Coverage Determination 30.3.3 Acupuncture for Chronic Low Back Pain Revised Frequency Edits Major private insurers like Aetna classify dry needling as experimental, investigational, or unproven and do not cover it, even while covering acupuncture for certain conditions like chronic neck or low back pain.7Aetna. Acupuncture and Dry Needling
Medicare covers acupuncture for chronic low back pain under specific conditions, allowing up to 12 visits in 90 days with an additional 8 sessions if the patient shows improvement, for a maximum of 20 treatments per year. Billing rules prohibit dry needling and acupuncture codes on the same visit.6CMS. National Coverage Determination 30.3.3 Acupuncture for Chronic Low Back Pain Revised Frequency Edits
For California patients, the insurance picture has a small upside. Because the only legal path to needling therapy runs through licensed acupuncturists or physicians, your treatment is more likely to be billed as acupuncture, which has broader insurance acceptance than dry needling. Out-of-pocket costs for acupuncture sessions in California vary widely but generally fall within the national range for dry needling, roughly $15 to $150 per session depending on the provider and region.
