How to Become a Medical Billing & Coding Specialist in CA

Medical billing and coding specialists play an essential role within healthcare organizations by reviewing provider documentation, assigning standardized codes, and managing insurance claims and reimbursement.

Accurate billing and coding ensure that providers are compensated appropriately, helping them continue delivering timely patient care. Because reimbursement depends on both correct coding and efficient billing, specialists trained in both skill sets are increasingly valuable across the healthcare landscape.

This work can be especially multifaceted in California, where the state’s large population, diverse network of insurance payers, and complex regulatory environment require professionals with strong attention to detail and up-to-date technical knowledge.

In this career guide, we outline the steps to becoming a medical billing and coding specialist.

*Required

Earn a High School Diploma or Equivalent

Whether you plan to enter the workforce directly or enroll in a medical billing and coding program, you will need a high school diploma or an equivalent credential such as a GED or HSE. Most employers and training programs also require you to be at least 18 years old.

If you apply to a program while under age 18, you may need parental or guardian consent. Some schools may have additional requirements such as entrance assessments, an admissions interview, or a background check. Requirements vary by institution, so always review program details before applying.

Complete a Medical Billing and Coding Program

While not required by the state of California, it’s common for employers to seek candidates who have completed a formal program in billing and coding — such as a diploma, certificate, or associate degree.

A Medical Billing and Coding Specialist training program helps build the foundational knowledge needed to interpret clinical documentation, apply the correct codes, and manage the full claims and reimbursement process for healthcare providers or insurance organizations.

In medical billing and coding school, you should expect to learn topics such as:

Medical coding systems (ICD-10-CM, ICD-10-PCS, CPT, HCPCS)
Medical and dental billing procedures
Billing for multiple types of healthcare plans
Insurance claims submission and follow-up
Reimbursement methodologies and denial management
Electronic health record (EHR) and billing software
State and federal health plan guidelines

Many aspiring medical billing and coding specialists choose diploma programs because they can often be completed more quickly than degree programs. For example, American Career College’s online Medical Billing and Coding Specialist program can be completed in less than 9 months. While coursework is completed 100% online, ACC students gain practical experience through a hands-on online practicum designed to reinforce real-world billing and coding skills.

When researching programs, look for an accredited institution that provides the support you need — whether that’s one-on-one career guidance, no-cost tutoring, or a flexible online learning format.

Earn a Medical Billing and Coding Certification (Optional)

California does not require medical billing and coding specialists to hold professional certification. However, earning a credential can demonstrate your knowledge and commitment to the field. Some employers may prefer or require certification.

Common certifications to consider include:

Certified Professional Biller (CPB) or Certified Professional Coder (CPC)– American Academy of Professional Coders (AAPC)
Certified Billing and Coding Specialist (CBCS) – National Healthcareer Association (NHA)
Certified Medical Reimbursement Specialist (CMRS) – Certifying Board of the American Medical Billing Association

Because many professionals work in roles that combine both billing and coding responsibilities, it can be beneficial to explore dual or complementary certifications.

If certification is a goal, look for a training program that incorporates exam preparation into its curriculum. ACC’s Medical Billing and Coding Specialist diploma program helps prepare students to sit for the CPB exam.
