Can You Hold Both a COTA and a PTA License? What All 50 States and DC Say

Yes. I read the occupational therapy and physical therapy practice acts and rules for all 50 states and DC, and nothing I could open stops one person holding both a COTA (occupational therapy assistant) license and a PTA license, or working as both. The two pieces I couldn't read are marked in the table. What every state does expect is that you work inside the license you are using at that moment: as a PTA under a physical therapist, as a COTA under an occupational therapist.

The question came from a COTA who is planning to become a PTA. Only one board, Ohio's, answers it directly. Five more states (Colorado, Florida, North Carolina, Texas and Vermont) have a rule or board guidance that bears on it. The rest say nothing about two licenses.

A note on who is writing. I'm an occupational therapist and the founder of Logicly, a scheduling app for home health clinicians. OT is my own profession; on the PT side, I've stuck to the PT boards' own words. I read each state's statute, administrative code or board rule on the state's own site and linked it below. This isn't legal advice. The rules were checked on November 9, 2026, and your board's current rule is the one that counts.

Two notes on words. COTA is NBCOT's certification mark; the state license is usually called occupational therapy assistant (OTA, OTA/L or COTA/L). I use COTA and OTA for the same person here. And a few states certify PTAs rather than license them (Colorado, Indiana, Kansas, Nebraska, Pennsylvania and Wyoming). The answer is the same there.

The Short Answer

• You can hold both. No state practice act or board rule I read stops one person holding an OTA license and a PTA license.
• You can work as both, one role at a time. Ohio's board says so for one employer, as long as you document which plan of care you're following and tell patients and colleagues which role you're in at each encounter.
• Each license keeps its own supervisor. As a PTA you work under a PT. As a COTA you work under an OT. Neither therapist can supervise the other role.
• Treating one patient in both roles is where it gets risky. No state forbids it outright, but the closest board guidance says don't switch back and forth or give both services at once, and Medicare bills a home health visit as one discipline.
• Two licenses means two renewals. Two fees, two sets of continuing education, and NBCOT renewal on top if you keep the COTA credential.

Every State at a Glance

No specific rule means the practice acts, the rules and the board's posted guidance say nothing about one person holding both licenses. The cited sections are the ones that apply anyway: the definitions that put a PTA under a PT and an OTA under an OT, and any rule on how you identify yourself. Related means a rule or board statement that doesn't name OTA and PTA but bears on working under two licenses; those states have their own section below.

Ohio: The One Board That Answers It

Ohio has one board for occupational therapy, physical therapy and athletic training, with a section for each. Its Physical Therapy Section's FAQ (opens in a new tab) asks the question almost word for word:

If I hold both a PTA and an OTA license, can I work in both roles in one job (e.g.: as a PTA in the morning and as an OTA in the afternoon)?

There is no law or rule prohibiting an individual from working as both an occupational therapy assistant and a physical therapist assistant for one employer. The individual would be required to document very clearly that the appropriate plan of care was being followed when working under either license, and would also be required to inform patients and other practitioners at each encounter which role was being filled.

The individual would need to meet the continuing education requirements for renewal of each license. That would not necessarily mean double the units since some courses might count for both licenses if attended during the appropriate time period.

Ohio's rules back up the signature side. A PTA "shall use the credential 'PTA' following their signature" (OAC 4755:2-2-06(B) (opens in a new tab)). An OTA without current NBCOT certification signs OTA or OTA/L, and one with it may sign OTA, COTA or COTA/L (OAC 4755:1-2-07(B) (opens in a new tab)). The same PT Section page (opens in a new tab) also says "an occupational therapist cannot supervise a physical therapist assistant."

Two cautions. The FAQ is board guidance, not a rule, and the OT Section's FAQ has no matching entry. Still, it's the clearest statement any board has made, and it's how I'd work in any state.

Five States With a Related Rule

None of these names OTA and PTA together. Each one bears on working under two licenses.

Colorado: say which license you hold

A 2025 law, the Know Your Health-Care Practitioner Act, added this to C.R.S. §12-30-102(8.5)(d) (opens in a new tab) (the board's copy of the statutes) for health-care practitioners, PT and OT included:

When establishing a practitioner-patient relationship, to facilitate patient understanding, unless emergent circumstances make it impracticable, a health-care practitioner, on first encounter with the patient, shall verbally communicate to the patient the practitioner's state-issued license, certificate, or registration or shall verbally identify themselves by a title or abbreviation authorized in statute for the practitioner.

It wasn't written for dual licensees. For you, it means naming the license you are working under. Colorado PTAs hold a certificate rather than a license.

Florida: tell patients the type of license

Florida's general law for health practitioners, F.S. §456.072(1)(t) (opens in a new tab), makes it grounds for discipline to fail to tell a patient which license you're practicing under:

Failing to identify through written notice, which may include the wearing of a name tag, or orally to a patient the type of license under which the practitioner is practicing.

There's an exception in the same paragraph (opens in a new tab): "This paragraph does not apply to a practitioner while the practitioner is providing services in a facility licensed under chapter 394, chapter 395, chapter 400, or chapter 429." Those chapters cover hospitals, nursing homes, assisted living and home health agencies, among others. Whether a visit in a patient's own home counts as "in a facility" isn't spelled out, so I'd follow the rule on every visit.

Vermont: discipline carries across

Vermont's Office of Professional Regulation issues both the PT and the OT licenses, and its general law, 3 V.S.A. §129(l) (opens in a new tab), says:

Unless a disciplinary order expressly provides to the contrary, discipline against any license or credential issued by a regulatory body attached to the Office to an individual or entity shall be applicable as a matter of law to all other licenses issued to that licensee by that regulatory body.

So a disciplinary order against your PTA license can reach your OTA license too, unless the order says otherwise. Vermont is the only state where I found this spelled out.

Texas: don't switch back and forth

The Texas PT Board has an FAQ (opens in a new tab) for people who hold "dual credentials." It was written for a PT who is also a personal trainer, not for OTA and PTA, and the Texas OT Board has nothing similar. But its reasoning is the clearest any board gives:

If you are a certified personal trainer, the PT Board cautions individuals who hold dual credentials not to blur the lines between the two as this can cause confusion or misunderstanding as to what service is being provided and could result in violations of the PT Practice Act/Rules. ... Additionally, you cannot switch back and forth when treating the same patient/client. The two services should be kept totally separate and apart from each other.

One more Texas detail. The PT rules say other letters "must follow the initials PT or PTA" (22 TAC §335.1(b) (opens in a new tab)), and the OT rules say the OT or OTA title "must precede any other titles" (22 TAC §369.3(e) (opens in a new tab)). Neither was written with a dual licensee in mind. My reading: sign each note with the one credential for the role you're in, and the clash never comes up.

North Carolina: one service, not both

The North Carolina PT board's position statement on PTs who are also massage therapists (opens in a new tab) is about another pairing, but it reaches the same place:

In conclusion, while there is no statute or rule that would prevent a dual licensee from representing that fact, the patient or client must understand that either physical therapy or massage therapy is being administered, not both. Likewise, the practitioner should not represent or imply that two services are being furnished at the same time.

What Holds in Every State

Two licenses don't merge into one bigger license. Each keeps its own act, its own supervisor and its own letters after your name.

• As a PTA, you work under a physical therapist. Every PT act I read says so in its definition of a PTA. The PT evaluates and sets the plan of care.
• As a COTA, you work under an occupational therapist. Same structure, different act, different supervisor.
• Neither therapist can supervise the other role. Your OT can't direct your PT work, and your PT can't direct your OT work.
• Sign with the credential of the role you're in. Most acts protect the titles, and many require PTA or OTA after your name. A few tie the signature to the role outright. Iowa: "The signature of an OTA on the occupational therapy treatment record indicates that occupational therapy services were provided in accordance with the rules and regulations for practicing as an OTA" (481 IAC 806.5 (opens in a new tab)). California's PT records must show each provider's "name and title ... including the individual's role in that service" (16 CCR §1398.13 (opens in a new tab)).
• Name tags show the license you're working under. New Jersey's PT rule is the plainest: wear the tag for PT or PTA "whenever acting in that capacity" (N.J.A.C. 13:39A-3.9 (opens in a new tab)).

Most acts also say they don't restrict someone practicing under another license, as long as that person doesn't claim to be the other profession. Hawaii's OT law is the only one I found that contemplates a dual licensee in those words: you can't claim to be doing occupational therapy "unless the person is also licensed under this chapter" (HRS §457G-5 (opens in a new tab)). Maryland's two acts go furthest the other way, saying they don't limit "the right of an individual to practice a health occupation that the individual is authorized to practice" (Health Occ. §10-102 (opens in a new tab); §13-102 (opens in a new tab)).

One board over both professions doesn't change the answer either. Alaska, DC, Iowa, Kansas, Massachusetts, Montana, Ohio, Oklahoma and Utah each have one board that licenses both, or advises on both, and only Ohio says anything about holding both licenses.

The National Layer

NBCOT

NBCOT certifies occupational therapy practitioners; the state licenses them. Its renewal handbook (opens in a new tab) says nothing about a second credential in another profession, either way. Two of its conduct principles still apply when you hold both. Certificants "shall be accurate, truthful, and complete in any and all communications ... as they relate to their professional work, education, professional credentials," and "shall comply with state and/or federal laws, regulations, and statutes governing the practice of occupational therapy." NBCOT renewal is 36 units every three years, on its own cycle, separate from your state OT license.

FSBPT

FSBPT runs the PTA exam, the NPTE. Its eligibility page (opens in a new tab) doesn't mention an OT credential, and there's no shortcut for a COTA: "jurisdictions will require that the candidate is a graduate of or graduating from a PT or PTA program that meets the accreditation standards of CAPTE or has an education that has been determined to be substantially equivalent by a recognized credentialing agency." The state board then approves you for the exam and issues the PTA license.

Medicare home health: one visit, one discipline

Medicare doesn't address a clinician who holds both licenses. What it does say settles most of the question for home health.

• Each visit is billed under one discipline. The claims manual, chapter 10 (opens in a new tab), says "each service visit (revenue codes 042x, 043x, 044x, 055x, 056x and 057x) must be reported as a separate line." A PTA visit goes under physical therapy (042x) with G0157; an OTA visit goes under occupational therapy (043x) with G0158. There's no line for half of each.
• Visits are counted by entries into the home. "Generally, one visit may be covered each time an HHA employee ... enters the beneficiary's home and provides a covered service," and "if all covered services could be provided in the course of one visit, only one visit may be covered" (42 CFR 409.48(c) (opens in a new tab)).
• Each discipline keeps its own therapist. "Where more than one discipline of therapy is being provided, a qualified therapist from each of the disciplines must functionally assess the patient" (Medicare Benefit Policy Manual, chapter 7, §40.2.1 (opens in a new tab)). Your OT's 30-day visit doesn't cover your PT work, and the other way round. The 30-day therapy reassessment rule has the details.
• Notes carry your occupation. Entries must include "a signature and a title (occupation)" (42 CFR 484.110(b) (opens in a new tab)).
• The agency checks each license. Medicare's personnel rules define an occupational therapy assistant and a physical therapist assistant separately, each with its own state license, education and exam (42 CFR 484.115(g) and (i)).

Put together: in home health, one trip into the home is one visit, billed as PT or as OT, signed with the matching title, under that discipline's order. A PTA or OTA visit is a visit under the therapist's order, never one of its own; which order an assistant works under explains why.

Working Under Two Licenses: What I'd Do

None of this is in a rule outside Ohio. It's how I'd keep both licenses safe.

Keep the roles apart in the record

• Separate notes for each role, under each discipline's plan of care.
• Sign each note with the one credential for that role: "Jane Doe, PTA" on the PT note, "Jane Doe, COTA/L" (or your state's form) on the OT note. Never both on one note.
• Name the supervising therapist where your state asks for it. Several do, on every PTA or OTA note.

One role per visit

• Don't switch roles inside a session. Texas's and North Carolina's boards both say as much about other dual credentials, and Medicare can only bill the visit as one discipline.
• Tell the patient who you are at each visit. Ohio's board expects it at each encounter, Colorado requires naming your license at the first encounter, and Florida requires it outside certain licensed facilities. It's simple courtesy everywhere else.
• If one patient needs both PT and OT, the cleanest answer is a different assistant for one of them. If your agency asks you to do both, make them separate visits on separate days, each under its own therapist, and get the agency's compliance lead to agree in writing first. If your agency won't put one person in both disciplines for the same patient, I think that's sensible.

Tell your employer, in writing

• Give HR both licenses to verify. In home health, the agency has to meet the personnel rules for each discipline you work in.
• Ask for two job titles, or at least a clear way to mark which discipline each visit is in the schedule and the EMR. The billing depends on it.
• Know who your PT supervisor and your OT supervisor are. They are two people.
• If you work PRN for more than one agency, every one of them needs to know which licenses you're working under there. Our guide to working PRN for more than one agency covers the rest.

Renewal and continuing education

• Two renewals, two fees, two deadlines. Put both on your calendar now.
• Two sets of continuing education. Ohio says some courses might count for both licenses; check that each board accepts a course before you count it twice.
• NBCOT renewal is a third cycle if you keep using the COTA credential. Not every state ties the OTA license to it (Ohio, for one, has OTAs without current NBCOT certification sign OTA or OTA/L), but NBCOT's handbook (opens in a new tab) says "An individual who has an Expired certification cannot use the OTR or COTA certification marks."

Compacts are separate too

The PT Compact covers PTs and PTAs; the OT Compact covers OTs and OTAs. A compact privilege for one license doesn't carry the other. Our licensure compact tool shows where each compact stands in each state.

Key Takeaways

• No state practice act or board rule I read stops one person holding both a COTA (OTA) license and a PTA license.
• Ohio's board is the only one that answers the question: working as both for one employer is allowed if you document which plan of care you're following and tell patients and colleagues which role you're in at each encounter.
• Colorado and Florida require telling patients which license you're practicing under; Vermont carries discipline from one license to the other; Texas's and North Carolina's PT boards say don't switch back and forth or give both services at once.
• As a PTA you work under a PT, as a COTA under an OT, and you sign with the credential of the role you're in.
• In home health, Medicare bills each visit as one discipline. Keep the roles in separate visits, with separate notes.
• This isn't legal advice. The rules were checked on November 9, 2026, and your board's current rule is the one that counts.

Frequently asked questions

Can you be licensed as both a COTA and a PTA?

Yes. I read the OT and PT practice acts and rules for all 50 states and DC, and nothing I could open stops one person holding an occupational therapy assistant license and a physical therapist assistant license at the same time. You have to earn each one in full: an accredited OTA program and the NBCOT exam for one, a CAPTE-accredited PTA program and the NPTE for the other, and a separate state license (a certificate in a few states) for each.

Can I work as a COTA and a PTA for the same employer?

Yes, as far as the state rules go. Ohio's board is the only one that answers it directly: no law or rule prohibits working as both for one employer, but you have to document clearly which plan of care you are following under each license and tell patients and other practitioners at each encounter which role you are in. Everywhere else the rules are silent, and Ohio's way of doing it is the safe one.

Can I treat the same patient as both a COTA and a PTA?

No state rule I found forbids it outright, but I wouldn't. The closest board guidance, written about other dual credentials, says no: Texas's PT board says you cannot switch back and forth when treating the same patient, and North Carolina's says the patient must understand which one service is being given, not both. In home health, Medicare bills each visit as one discipline. If your agency allows it at all, make them separate visits, under separate supervising therapists, and ask before you do it.

Does a COTA have to go back to school to become a PTA?

Yes. To sit for the PTA exam, FSBPT's eligibility rules require graduation from a PTA program that meets CAPTE's accreditation standards, or an education found substantially equivalent. An OTA degree and NBCOT certification don't count toward it. Then the state board approves you and issues a PTA license of its own.

Do I need continuing education for both licenses?

Yes. Each board's renewal rules apply to its own license, with its own fee, hours and deadline. Ohio's board says that doesn't necessarily mean double the hours, because some courses might count for both licenses. Check that each board accepts a course before you count it twice. NBCOT renewal is a third cycle if you keep the COTA credential.
