Seeing a Physician Assistant for Primary Care in Texas

Innovare Tx November 11, 2026 6 min readEducational information, not medical advice

TL;DR: In Texas, a physician assistant (PA) provides medical services that a supervising physician delegates and that are within the PA's education, training and experience. That can include taking your history and examining you, ordering tests, making a working diagnosis, building and adjusting a treatment plan, prescribing under the delegation rules, and referring you on. The supervising physician oversees the PA's work and accepts responsibility for it. A PA is not a physician, and care outside what has been delegated goes to a physician. At Innovare Tx, primary care is with Charles Ortega, PA-C, MPAS, supervised by Dr. Nathan V. Nguyen, MD.

What a physician assistant can do in Texas

The Texas Physician Assistant Licensing Act describes a PA's practice as medical services delegated by a supervising physician that are within the PA's education, training and experience (Texas Occupations Code §204.202). The law lists services a PA may provide, including:

  • Taking patient histories and doing physical examinations.
  • Ordering or performing diagnostic and therapeutic procedures.
  • Making a working diagnosis.
  • Developing and carrying out a treatment plan, and checking whether it is working.
  • Counseling and education.
  • Prescribing or ordering a drug or device under the delegation rules in chapter 157.
  • Making appropriate referrals.

For primary care, that covers most of what a first visit involves: your history, an exam, lab work, a plan for an ongoing condition such as high blood pressure or diabetes, and a referral when you need one.

How supervision works

Every PA in Texas has at least one supervising physician, who oversees the PA's activities and accepts responsibility for the medical services the PA provides (§204.204). Supervision must be continuous. It does not require the physician to be physically present all the time, but the physician and the PA must be in contact, or able to be in contact easily, by phone or another telecommunication device. For delegated services within the PA's scope and set out in the physician's protocols or practice guidelines, the PA acts as the supervising physician's agent (§204.202(e)).

What goes to a physician or a specialist instead

A PA works inside two limits: what the supervising physician has delegated, and the PA's own education, training and experience. Care outside those limits is not the PA's to give. In practice that means:

  • Specialist care. When a condition needs a specialist, such as a cardiologist or a surgeon, the PA refers you. Making appropriate referrals is part of the job the law describes.
  • Programs that require a “physician.” Some programs define physician narrowly. Federal workers' compensation is one: its definition (5 U.S.C. §8101(2)) does not include physician assistants. That is why, at Innovare Tx, Dr. Nathan V. Nguyen, MD is the treating physician on federal workers' comp (OWCP) cases.
  • Emergencies. For a medical emergency, call 911 or go to the nearest emergency room.

Questions worth asking any PA-led practice

  • Who is the supervising physician?
  • When would you refer me to a physician or a specialist, and to whom?
  • How do I reach the practice with a question between visits?
  • Does my health plan let me list this practice as my primary care provider? This depends on your plan, so ask your insurer, especially if you have an HMO.

A good practice will answer all of these plainly. You can ask us the same questions at (214) 233-3094.
