Become a Nationally Certified Medical Biller through AMBA
Information for medical billing certification
of the CMRS Exam
The purpose of this certification is to promote ethical and
professional medical billing through certification of qualified individuals.
This voluntary credential formally recognizes a medical biller’s competency and
proficiency, encourages continued professional and personal best development,
and provides a national standard assessment based on industry knowledge.
Created in 2000, it is the longest standing and most
thorough exam for professional medical billers. Other exams offered to medical
billers are newly released, offer a fraction of the questions, are sometimes
more expensive, and are offered by associations that primarily focus on medical
coding, a separate industry from medical billing.
The CMRS designation is awarded by the Certifying Board of the American Medical
Billing Association (CBAMBA). Currently, no state or Federal requirements exist
stating a medical biller must be certified to practice medical billing.
However, most providers are requiring their billers be certified. Your
certification demonstrates to physicians and employers that you are proactive
in advancing your education and skills.
Certified Medical Reimbursement Specialists (CMRS) facilitate the claims paying
process, from the time a service is rendered by a health care provider, until
the balance is paid. CMRS Billers play a critical role in a health care
provider's daily business operations.
Certification provides knowledge and
credibility to the biller, potential health care providers, and employers. It
demonstrates your commitment and dedication in providing the highest standards
possible in Claims Management and Medical Billing. Certification presents solid
confirmation of your desire to offer qualified services in an industry that is
complex and demands specialized training. Certification provides verification
of competency and assurance of continued education to maintain the credential.
CMRS testing is provided on a global level. Our credential allows billers to
empower themselves by taking steps to improve confidence and enhance value to
the industry and the doctors they work with.
Physicians and other healthcare providers are looking for certified
professionals that understand regulatory and business issues that affect their
practices. CMRS's have the knowledge, skills, and confidence to be more
effective in increasing revenue, preventing fraud and abuse, and researching and
finding information that helps practices succeed in today's environment and

How The Exam Works
The CMRS Exam is taken online
through our secure Learning Management System. We are not concerned with a
student retaining every detail in their memory. A biller must be able to
utilize all of their resources to find solutions, and we expect the same
utilization during the testing process. For example, a biller must know how to
search the OIG’s exclusion list to answer why a person/company is excluded from
Medicare and Medicaid programs. Also, a biller should be able to research an
insurance carrier’s website for policy provisions and payment information. Our
exam covers both of these topics, and a multitude of others, that a biller will
have to face on the job.
