Medical assistant certification in Colorado

Read the official rule (C.R.S. § 12-240-107(3)(l); 3 CCR 713-1 Rule 1.17; 6 CCR 1007-1 Part 2)

Colorado does not require medical assistant certification, and there is no state license for this role. What you may do on the job comes from what a physician assigns to you under Colorado's delegation rule.

The Colorado medical assistant programs page lets you choose one accredited program and ask that school for details.

Working with no state license

There is no Colorado medical assistant license to seek. The guide is Colorado Medical Board Rule 1.17, formerly Rule 800, which explains what a physician can pass to unlicensed staff. Delegation means the physician gives you a task and remains answerable for how it is carried out.

A physician assistant may delegate to unlicensed workers too, provided you work under that person's direct supervision.

Does a CMA or RMA credential change anything?

No. Colorado uses the same delegation rule for you whether you hold a national credential like CMA or RMA or not. By itself, that certificate adds no extra duties in this state.

Your schooling still counts. Before a physician assigns a task, they must personally review diplomas or certificates from a genuine training program that teaches that exact service. A program that builds the skills a clinic uses gives you the documents a physician will want to check.

Tasks you can do without delegation

Some routine work is treated as collecting information rather than delivering medical care, so it sits outside the delegation rule. These count as gathering information, not medical services, so the delegation rule does not cover them:

  • Collecting blood samples
  • Checking vital signs
  • Recording a patient's history

What can a physician hand to you?

For any other medical service, the physician follows a set process before you work independently. They look over your training records for that service. Next, they observe you doing it in person before allowing you to do it when they are not in the room.

By default, the physician must be on the premises. When the clinic keeps thorough written procedures for routine care and urgent situations, the physician only needs to be somewhere in Colorado and able to get there quickly.

Oversight keeps going. The physician must review how well you handle delegated tasks at least every 2 weeks, at the site where you perform them, and check your skills again at least yearly.

Refills and prescriptions

A physician can never hand prescribing to you. You may order a refill of the same medication at the same dose when you follow a written refill protocol approved by a delegating physician. A protocol means written steps the clinic follows each time.

Cosmetic and aesthetic services

HB25-1024 gives physicians and advanced practice nurses new responsibilities when they pass medical-aesthetic work to unlicensed staff. They have to post notices, have every patient sign a consent form, and hold on to each form for 7 years or more. If you'd like to work in a medical spa or cosmetic clinic, expect the physician or nurse you work for to post these notices and keep signed consent forms on file.

The Limited Scope Operator credential for x-rays

X-rays are different: here Colorado does require a state registration. Before anyone takes x-rays of patients, Colorado requires registration as a Limited Scope Operator, unless they already hold ARRT radiography registration or another exemption on the list. A Limited Scope Operator is a person trained to take a small group of basic x-rays.

Training calls for at least 480 hours of supervised clinical practice. After you pass the required exam, you may image the skull, chest, hip and pelvis, arms and legs, plus the spine and sacrum. If x-rays appeal to you, choose a program that keeps this goal in mind from day one.

Picking a training program

Because Colorado does not define the training, the program you pick shapes what a physician will see on your documents. Nationwide, we list 1,094 medical assistant programs, with 484 accredited by CAAHEP or ABHES. Accreditation tells you an outside group has measured the program against national standards.

Item to compareTypical number
Length of study at career schools9 months (median)
Total program cost at career schools$17,257 (median)
One year of full-time public-college tuition$4,346 (median, in-district)

These figures are drawn from federal school data for 2023-24. A few programs offer coursework online, while hands-on clinical practice always happens in person.

Pay for medical assistants

Across the country, median pay for medical assistants was $45,690 per year in May 2025, about $21.97 an hour, based on Bureau of Labor Statistics figures. That is near phlebotomists at $45,230 and above nursing assistants, who earned $42,260.

Your training is what a Colorado physician checks before trusting you with patient care, so start there. Pick an accredited program on the Colorado programs page and use its Request information form with your name, email, phone, ZIP code and start time to ask that school for details today.
