Medical Assistant Scope Of Practice In Texas

What the Texas Medical Board Actually Allows

The Texas Medical Board doesn't certify or license medical assistants the way it does for nurses. That means there is no standalone "scope of practice" document you can download and hand to a new hire. What exists is a framework of delegated duties, and that distinction matters more than most people realize. I worked at a multi-provider clinic outside Houston where we had three full-time MAs. We went through exactly this confusion when we hired someone who'd been certified in another state and assumed she could pull a wider range of tasks. The board's position is clear: anything an MA does must be delegated by the supervising physician, and the physician remains personally responsible for any mistake that happens under that delegation. I learned that the hard way when we got an audit flag over an MA who'd been giving intramuscular injections without a standing order that explicitly covered it. The order said "administer medications as directed" — which sounded fine until someone pointed out that Texas Administrative Code Title 22, Section 164.25 requires specific, individualized physician orders for each medication administration route. We pulled the MA off injections immediately and rewrote our entire delegation protocol. Took us about three weeks to get everything documented properly.

Understanding Medical Assistant Scope Of Practice In Texas

Here is how the actual breakdown looks in a working clinic. Clinical tasks that are routinely delegated include vital signs and measurement, patient history documentation, preparing examination rooms, sterilizing instruments through autoclave cycles, performing basic point-of-care testing like rapid strep or glucose checks, administering immunizations under a physician's standing order, applying non-sterile dressings, removing sutures and staples, performing EKGs, and patient education related to medications and post-procedure care. Things MAs in Texas generally cannot do without crossing into unlicensed practice territory: independent assessment or diagnosis, interpreting lab results, initiating or adjusting treatment plans, prescribing medications, performing sterile procedures like IV insertion or phlebotomy unless explicitly delegated with a standing order, and administering IV medications. Phlebotomy is a common gray area. Some clinics have MAs draw blood. The board hasn't explicitly banned it, but they haven't explicitly authorized it either. If you're doing it, make sure your delegation language is precise and your physician is comfortable owning those draws. The administrative side of the scope is less contentious. Scheduling, billing, coding, answering phones, managing patient records, insurance verification — these are generally uncontroversial because they don't involve clinical judgment. But even here there are edge cases. Data entry into the EHR that amounts to clinical documentation still needs to comply with your facility's documentation policies. I once had a situation where a billing MA updated a patient's chief complaint field directly in the chart instead of flagging it for the provider. The compliance officer flagged it as unauthorized practice. Simple fix, but it cost us two days of back-and-forth emails.

Setting Up Delegation That Actually Holds Up

Most clinics I've seen do this poorly. They write one generic delegation form that covers everything and file it away. That works fine until someone changes roles or a new physician joins and tries to delegate something outside the original language. The workaround I use now is a task-specific delegation matrix that maps each clinical procedure to an individual physician's written authorization. It takes longer to set up, maybe an afternoon per provider, but it prevents the exact scenario that caught us at that Houston clinic. Each delegation should specify the task, the conditions under which it can be performed, the level of supervision required — immediate, on-site, or available by phone — and the process for revoking that delegation. You should also document competency validation. A signature on a piece of paper saying "I trained Maria in flu shot administration" is not sufficient documentation if you get audited. I keep a log that includes the date of training, the method used, the competency checklist completed, and the date of periodic re-evaluation. Annual review keeps everything current without requiring a complete restart. There is a real limitation here that nobody likes to talk about. This system only works if your physicians are willing to engage with it. I've been at clinics where the delegation paperwork was technically perfect but the providers were delegating tasks to MAs without documenting it. The gap between what the paperwork says and what actually happens in the clinic is where liability lives. No amount of forms will fix a culture problem. The best clinics I've worked with made it routine for physicians to sign off on delegation updates during their quarterly compliance reviews. That consistency matters more than having the most detailed policy document on the shelf.

For those looking for the official language, the Texas Medical Board's Rules regarding Medical Assistant Duties are in Title 22 of the Texas Administrative Code, Section 164.25. The Texas Occupations Code Chapter 159 also touches on this. Neither gives you a clean list of allowed and forbidden tasks. They give you the framework and leave the specifics to physician delegation. That ambiguity is by design and it's the part most people struggle with.
