Oregon wrote the
widest chiropractic
scope in America
in two sentences.

Almost every scope argument in Oregon turns on which half of ORS 684.010(2) you are standing in. The two clauses were not written to do the same work, and the Court of Appeals has confirmed they don't.

Clause (a) — the closed list

Adjusting by hand, physiotherapy, electrotherapy, hydrotherapy, and minor surgery. Five named categories. If a procedure isn't one of those things, clause (a) will not carry it. This is the clause that killed the Board's dry needling rule in 2014: the court asked whether inserting a filiform needle was "physiotherapy," decided it wasn't, and struck the rule down as beyond the Board's authority.¹⁸

Clause (b) — the elastic one

Diagnosis, treatment and prevention of body dysfunction using "all recognized and accepted chiropractic diagnostic procedures" and "all rational therapeutic measures as taught in approved chiropractic colleges." That last phrase is the load-bearing wall. It ties Oregon's scope to what CCE-accredited colleges teach — a moving target the Board tracks through its Examinations, Tests, Substances, Devices and Procedures committee.¹⁰

The practical consequence: Oregon's scope grows through curriculum and committee, not through the legislature. Functional chiropractic neurology and Network chiropractic were both added to the "standard" column by ETSDP recommendation and a Board majority vote in April 2025 — no bill, no hearing in Salem.³

Three words that unlock the rest of the chapter

"Chiropractic physician." ORS 684.010(3) defines the licensee as a physician and, specifically, as an attending physician.¹ That single word is why an Oregon DC can sign a death certificate for a patient treated in the prior twelve months, qualify an established patient for a disabled parking placard, perform a federal DOT commercial-driver medical exam, and serve as a portal-of-entry provider with no referral required.³ Washington, Michigan and New York have all concluded the DOT exam falls outside chiropractic scope in their states — the Board's own policy footnotes this.³ Michigan chiropractors were still contesting their exclusion in late 2025.

What "portal of entry" actually authorises

• Take a history and perform any component of a physical examination
• Order and perform diagnostic tests — labs, imaging, special tests
• Build a differential and formulate a diagnosis
• Order preventive services, health maintenance and disease screening
• Act as attending physician, refer, coordinate and co-manage with other providers³

Insurers may still impose referral and authorisation requirements. The Board is explicit that those sit outside its jurisdiction.³

Imaging is one of the widest permissions in the chapter

OAR 811-030-0020 lets a chiropractic physician order or refer for any diagnostic imaging study, contrast studies included.¹² The limits are narrow and specific: radio-opaque substances may only be given by mouth or rectum; a pregnant patient is not radiographed unless the symptoms are significant enough that treatment would otherwise be jeopardised; and fetus, eyes and thyroid outside the primary field must be shielded.¹² Staff may take films only with an Oregon Board of Medical Imaging permit, and that permit covers taking films and nothing else.²⁸ The full text of every rule cited on this page sits in OAR chapter 811.⁴

What Oregon permits that most of the country doesn't

The last comprehensive survey of US chiropractic practice laws found that 90% or more of jurisdictions place minor surgery and limited prescription rights outside chiropractic scope entirely.²⁴ Oregon keeps minor surgery in the statutory definition — a definition whose amendment history runs back to 1953.

Capability	Oregon	The condition
Minor surgery	CERTIFICATE	36 hours coursework plus a supervised rotation of ≥25 cases, five performed solo8
Proctology	CERTIFICATE	Same rotation pathway; includes fissurectomies and rectal electrotherapy38
Obstetrics / natural childbirth	CERTIFICATE	200 instruction hours, 50 prenatal/postnatal patients, 50 attended births, board exam8
Injectable lidocaine	TIED TO SURGERY	1% plain, 1% with 1:100,000 epinephrine, or 2% plain — only in connection with minor surgery3
Pap smear, STI testing, GU exam	IN SCOPE	No extra certificate. The general PARQ and clinical-justification rules apply135
Sign a death certificate	IN SCOPE	Must have treated the decedent within the preceding 12 months3
Colonic therapy	IN SCOPE	No conditions stated for the physician; excluded for assistants3
Venipuncture and lab work	IN SCOPE	Performing in-house requires a CLIA certificate or waiver3
Any prescription drug	PROHIBITED	No prescriptive authority in statute. Also bars recommending a patient stop or change a prescription3
Dry needling / acupuncture	PROHIBITED	Rule invalidated by the Court of Appeals in 2014; OAR 811-015-0036 now repealed18

Oregon lets a chiropractor excise a superficial lesion under injectable anaesthetic, but not insert a solid needle into a trigger point. That is not an oversight. It is the exact line the courts drew.

A certified chiropractic assistant in Oregon is licensed to deliver three things: physiotherapy, electrotherapy and hydrotherapy — plus vitals, height, weight and body fat.¹¹ Everything else in a CA's day is either explicitly permitted by a named Board policy or it is unauthorised practice, and the physician wears the consequence.¹⁴

What a CA may never do, no matter how well trained

• Perform a physical examination or take an initial history
• Interpret a postural screening
• Perform manual muscle testing — device-assisted range of motion is allowed, but not the interpretation
• Perform any osseous adjustment or manipulation¹¹
• Order anything: no imaging, no labs, no electrotherapy orders, no durable medical equipment
• Make a referral, except in an emergency³

The supervising physician must be on the premises whenever a CA is working, and a CA who has not renewed by the end of the grace period must stop practising outright.¹¹

Three routes into the certificate

Standard route: a 12-hour approved course — eight hours didactic, four hours practical in physiotherapy, electrotherapy and hydrotherapy — completed within the 60 days before applying, plus the NBCE open-book exam¹¹ and fingerprinting.³¹⁶ A chiropractic student who has passed physiological therapeutics coursework may substitute a transcript for both the course and the exam. And since April 2025, a physical therapist assistant may substitute a PTA transcript or five years of PTA employment for the 12 hours — but still sits the exam.³

The PARTS rule changed in 2020

OAR 811-015-0010 now requires that every initial and subsequent examination for a neuro-musculoskeletal condition include a functional chiropractic analysis made up of at least two of the PARTS elements — Pain on palpation, Asymmetry, Range of motion loss, Tone/texture/temperature, Special tests. The current rule also states flatly that there is one standard of care for all patients regardless of the condition or service, and that the history must inform the examination, the examination the diagnosis, and the diagnosis the management plan.⁵

If you learned this rule as simply "some combination of PARTS," re-read it: since January 2020 the rule reads "some combination of at least two," and that floor plus the single-standard-of-care sentence are the version an investigator will hold you to.

Oregon's headline permissions are not automatic with the licence. Minor surgery, proctology and obstetrics each require a separate certificate of special competency issued by the Board after a documented clinical rotation.⁸ Manipulation under anaesthesia sits alongside them as a policy-gated privilege. Animal chiropractic moved into rule in July 2024 — OAR 811-015-0031 requires a written referral from a licensed veterinarian and bars imaging, surgery and medication — with the post-graduate-program requirement still sitting in Board policy.³³⁰

They also carry their own discipline exposure: when a complaint concerns certificated work, the Board may suspend or revoke only the certificate and leave the underlying licence intact.⁸

Everyone takes the surgery exam, almost nobody uses it

Here is a genuine oddity of Oregon licensure. Every applicant — including someone who will spend a career doing nothing but spinal manipulation — must pass the NBCE's Oregon-specific Minor Surgery and Proctology exam and Obstetrics, Gynecology and Genitourinary exam, alongside ethics and jurisprudence.²⁵ Passing those exams does not confer the certificates. They test the ceiling of the statute, not the floor of practice.

The practical read: Oregon licensure screens for a breadth of competence that the profession's actual utilisation almost never reaches. That gap — a broad legal scope, a narrow practised scope — is the single most useful thing to understand about this state.

Legal scope is only the first constraint. A second, tighter set of rules decides who pays and for how long — and in Oregon those rules cut the practised scope down substantially, particularly on the injury side of a practice.

Workers' compensation: the 60/18 ceiling

Oregon classifies chiropractic physicians as Type B providers. A Type B provider may serve as attending physician for a cumulative 60 days or 18 visits, whichever comes first, counted from the first visit on the initial claim with any Type B provider — so a naturopathic physician who saw the worker first burns the same clock. Physician associates and nurse practitioners are no longer in this category: since House Bill 4040 (2026) they are full attending physicians.²¹³² Temporary disability may be authorised for no more than 30 days from that first visit.

Before providing any compensable service, a Type B provider must certify to the director that they have reviewed the director's materials packet, and must notify the worker at the first visit of exactly these limits.²¹²⁷²²

One carve-out matters and is easy to miss: Type B providers may not make impairment findings — except a chiropractic physician who is the attending physician at claim closure.²¹ That is a chiropractic-only exception inside the Type B category.

Motor vehicle injury: two years, fifteen thousand dollars

Every Oregon auto policy carries personal injury protection. PIP pays all reasonable and necessary medical expenses incurred within two years of the injury, capped at $15,000 per person — a longer window than most states and one of the reasons Oregon supports substantial chiropractic injury practice.²³

Two provisions do real work for a treating clinic. First, expenses are presumed reasonable and necessary unless the insurer sends the provider a denial within 60 calendar days of receiving notice of the claim. Second, during the first 50 days the provider must answer the insurer's written questions within 10 business days — miss that and the insurer's 60-day denial clock stops running until you answer.²³

Separately, ORS 742.525 pegs PIP medical charges to the workers' compensation fee schedule, which is why an Oregon PIP claim does not pay like a cash or commercial claim.

Licence upkeep, and what it now costs

The licence period runs to the last day of your birth month. Twenty CE hours a year for regular active status, six for senior active, none for inactive — plus fingerprint background checks every six years.⁷¹⁶ At each renewal the Board randomly audits at least 10% of renewing licensees, who then have 30 days to produce proof.⁷ The grace period is 30 days of continued practice, but the penalty is $150 per week with no cap, and practising past the grace period is unprofessional conduct.¹⁴¹⁶

What actually draws a complaint

The Board's own case data, presented to the legislature in February 2025, groups complaints into four buckets: unprofessional conduct, licensing and CE, treatment, and sexual misconduct. Unprofessional conduct is consistently the largest category. Sexual boundary matters are serious enough to have their own dedicated rule, OAR 811-035-0019, and their own key performance measure — one the Board reported it was not meeting for resolution within 180 days.¹⁷

Two structural points worth internalising. Practising outside the scope of chiropractic is itself enumerated unprofessional conduct.¹⁴ And an owner-physician can be held responsible for staff conduct, for inadequate supervision and training, and for exerting undue influence on an associate's independent clinical judgement.¹⁴

The Board's presentation charted complaint counts by category and year but did not publish the underlying figures in machine-readable form, so no counts are graphed here.

The records request clock

When the Board asks for a patient file in a complaint or investigation, you have 14 days to produce it, and you must certify that everything requested has been provided. Failure to meet that deadline is itself a rule violation.⁵

In May 2011 the Board adopted OAR 811-015-0036 authorising chiropractic physicians to perform dry needling after a short course of training (contemporary accounts put it at roughly 24 hours). The Oregon Association of Acupuncture and Oriental Medicine petitioned for judicial review, obtained a stay, and in January 2014 the Court of Appeals declared the rule invalid.¹⁸

What matters is how the court got there. The Board's defenders argued dry needling was treatment by physical or mechanical means and therefore physiotherapy, and separately that clause (b) captured it as a "rational therapeutic measure." The court took the first argument, rejected it, and stopped: because dry needling was not physiotherapy and no other clause (a) category was claimed, it was not chiropractic, and the rule exceeded the Board's authority.¹⁸

The rule is now formally repealed. Acupuncture and acupuncture as anaesthesia sit on the Board's current Out of Scope list, and intradermal injection is on its Substances list as not within scope.³

Clause (b) is broad, but it cannot rescue a procedure that fails clause (a). Any scope expansion argued only from "our colleges teach it" is standing on the leg the court already kicked out.

The asymmetry arriving on 1 July 2027

House Bill 3824, signed 7 August 2025 as Oregon Laws 2025 chapter 627, authorises physical therapists to perform dry needling, with training requirements to be set by the Oregon Board of Physical Therapy by rule. Most of the Act — including that section — becomes operative 1 July 2027.¹⁹²⁹

The Board of Physical Therapy has sequenced the work: following the Governor's signing letter, a main workgroup covering every section other than dry needling meets first, from October 2026, while a separate dry-needling workgroup formed in consultation with the Oregon Medical Board is not expected to begin until February 2027 — a tight run to the 1 July 2027 operative date. As of September 2026, rulemaking on needling had not begun.²⁰

So from mid-2027, on current law: a physical therapist in Oregon may insert a needle. A chiropractic physician — who may excise a superficial lesion and inject lidocaine to do it — may not. The legislature gave PTs by statute exactly what the courts denied the chiropractic board by rule. If Oregon chiropractic ever regains needling, the 2014 decision means it has to come from the legislature, not from the Board.

How the scope actually moved, 1907 to 2027

Where this reading could be wrong

Three honest counterweights to the picture above.

"Broadest scope" is a claim about the statute, not the street. The 2014 national survey ranked states by counted services and put Missouri, New Mexico, Kansas, Utah and Oklahoma at the top — Oregon was not in that leading group.²⁴ Oregon's distinction is specific and unusual (minor surgery, proctology, obstetrics, GU examination) rather than a uniformly higher count. That survey is also now over a decade old and its authors flagged that answers came from officials of varying rank. Treat state rankings as indicative only.

The policy Guide is interpretation, not law. Every entry in the Sounder above reflects a Board position adopted under ORS 684.155 and OAR 811-010-0093. Positions change, the Out of Scope list is explicitly "regularly updated," and a court can invalidate a Board position — as one did in 2014. For anything with real money or liability attached, read the underlying statute and rule, and call the Board.

Wide scope does not mean wide payment. A procedure can be squarely in scope, taught in an accredited college, ratified by the Board — and still be unpayable under a workers' comp fee schedule, an MCO utilisation standard, or a commercial plan's visit cap. The Board says this itself in the portal-of-entry policy.³ Scope research answers "may I," never "will I be paid."

Adjacent water worth sounding

Horizon — things that exist just outside this report

• Oregon Chiropractic Practices and Utilization Guidelines (OCPUG). The volume the clinical justification rule points to for treatment frequency and duration. Practising outside its frequency-and-duration guidelines puts the burden of proof on you (OAR 811-015-0010). Worth reading in full if you carry chronic cases.²
• OAR 811-035-0019, sexual unprofessional conduct. A standalone rule with its own subsections, now the primary citation in boundary cases rather than the general unprofessional conduct rule.
• Oregon Board of Medical Imaging permits. A staff member may take radiographs only with an OBMI permit, and that permit authorises taking films and nothing else.²⁸
• The substances list. Colloidal silver is permitted topically but a licensee may not manufacture it for ingestion or retail; ivermectin, HCG and ethyl chloride are out. The list is explicitly non-exhaustive and changes by ETSDP referral.³
• Vaccination during a declared emergency. Vaccines are out of scope "other than during a declared state of emergency or otherwise authorized by Oregon Health Authority" — a dormant authority that has been switched on before.³
• HB 3824's non-needling sections. The same Act lets physical therapists sign disabled-person parking permits and exempts PT-purpose sonography from imaging licensure. Both overlap services Oregon chiropractors currently provide.¹⁹
