The PA-C medical abbreviation stands for Physician Assistant, Certified, the credential a physician assistant may use after passing the national certifying exam and while keeping that certification current. The letters typically follow the clinician's name on ID cards, prescription labels, visit summaries and chart signatures.
Patients sometimes wonder whether a PA-C is different from a PA. The role is the same; the C shows active national certification, which most states require for a license. This page explains how someone earns those letters, how they keep them, what a PA-C can do, and how the credential compares with others you may see.

What the PA-C medical abbreviation tells you
Every PA-C is a physician assistant, but the letters add a specific fact: the person holds current certification from the national body that certifies PAs in the United States. To be allowed to sign with the C, the clinician must have graduated from an accredited program, passed the national certifying exam and kept up the requirements since.
The credential is separate from a state license. Licensing lets a PA practice in a given state, and most states use national certification as one condition of that license. A PA whose certification has lapsed may drop the C, although rules about whether they can still practice depend on the state.
How a physician assistant earns the C
- Prerequisites: a bachelor's degree, science coursework and, in most programs, hands on patient care hours before admission.
- PA school: a graduate program, commonly about 27 months, with a year or so of classroom medicine and then clinical rotations in areas such as family medicine, surgery, emergency care, pediatrics and women's health.
- National exam: a broad test of medical knowledge taken after graduation.
- State license: granted by the state medical or PA board, often with the national certification as a requirement.
Program length and exact steps vary, and many graduates earn a master's degree such as a Master of Physician Assistant Studies at the same time.
Keeping the certification current
The C is not permanent. Certified PAs log continuing medical education hours on a regular cycle, commonly 100 hours every two years, and take a recertification assessment about once every ten years. They also pay maintenance fees to the certifying body. If those steps are missed, certification lapses until the PA meets the reinstatement rules.
Some PAs also earn added certificates in specialties such as emergency medicine, orthopedic surgery or psychiatry, which show extra training on top of the general PA-C credential.
Reading PA-C on a chart or label
Visit summary: "Seen by: Family Medicine, PA-C. Supervising physician on file." A certified physician assistant led your visit, and the clinic keeps a record of the physician the PA works with under state rules.
Operative note: "First assist: PA-C." A certified PA helped the surgeon during the operation, for example by holding tissue, controlling bleeding and closing the wound.
On a prescription bottle the prescriber name may be followed by PA-C, which simply shows who wrote the order.
PA-C compared with other credentials
| Credential | Meaning | Training path |
|---|---|---|
| PA-C | Physician Assistant, Certified | Graduate PA program plus national exam |
| MD | Doctor of Medicine | Medical school plus residency |
| DO | Doctor of Osteopathic Medicine | Osteopathic medical school plus residency |
| FNP | Family Nurse Practitioner | Registered nurse, then graduate nursing program |
PAs and nurse practitioners are often grouped as APPs. You can compare more letters in the guide to clinician credentials.
Credentials describe training, not the full picture of a clinician's role in your care. Questions about who directs your treatment are best put straight to the clinic or the care team.
Frequently asked questions
What does PA-C stand for?
PA-C stands for Physician Assistant, Certified. It shows the physician assistant passed the national certifying exam and has kept that certification current.
What is the difference between PA and PA-C?
PA names the profession, while PA-C adds that the person holds current national certification. In daily practice nearly all working PAs are certified, so the two often refer to the same clinician.
Can a PA-C prescribe medicine?
Yes, PAs can prescribe in all US states, including many controlled medicines, though the exact limits are set by each state and sometimes by the employer.
Is a PA-C a doctor?
No. A PA-C holds a graduate PA degree and a license to examine, diagnose and treat, yet has not gone through medical school or complete a physician residency.
How long does it take to become a PA-C?
After a bachelor's degree and patient care experience, PA school commonly lasts a little over two years. Graduates then pass the national exam and apply for a state license.
