Charles Ortega, PA-C, MPAS
Physician assistant, co-founder and lead provider at Innovare Tx in Addison, practicing under the supervision of Dr. Nathan V. Nguyen.
What a physician assistant does
A physician assistant is a licensed medical provider who works under a supervising physician. In Texas, a PA provides medical services that the supervising physician delegates and that fall within the PA's education, training and experience. Under Texas Occupations Code §204.202, 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 making referrals. Supervision must be continuous. The supervising physician does not have to be physically present at all times, but the two must be able to reach each other easily.
Charles is a physician assistant, not a physician. His supervising physician is Dr. Nathan V. Nguyen, MD, who co-founded the clinic with him. Read more in seeing a physician assistant for primary care in Texas.

Some care belongs with a specialist or a hospital. When your evaluation points to a problem that needs one, a referral is part of a physician assistant's role, and for a medical emergency, call 911 or go to the nearest emergency room.
