In the complex world of healthcare, accurate communication between providers, patients, and insurers is crucial—not just for care delivery but also for financial sustainability. Medical billing and coding is the engine that drives this process. Though often behind the scenes, this field is essential for healthcare facilities to receive reimbursement, maintain compliance, and ensure smooth patient experiences.
What Is Medical Billing and Coding?
Medical billing and medical coding are interrelated but distinct processes:
- Medical Coding is the process of translating healthcare diagnoses, procedures, services, and equipment into standardized codes using systems like ICD-10, CPT, and HCPCS.
- Medical Billing is the process of submitting and following up on claims with health insurance companies to receive payment for services rendered by healthcare providers.
Together, these functions serve as a bridge between clinical care and financial reimbursement.
Who Performs Medical Billing and Coding?
Medical billing and coding is typically done by certified professionals known as Medical Coders and Medical Billers. In many settings, the roles are combined into one position called a Medical Billing and Coding Specialist.
These professionals work in:
- Hospitals and clinics
- Physician’s offices
- Health insurance companies
- Long-term care facilities
- Telehealth organizations
- Billing service companies
They are often part of the Health Information Management (HIM) team.

Qualifications Needed to Work in Medical Billing and Coding
You do not need a medical degree, but formal training and certification are highly recommended and often required.
Typical qualifications include:
- Education:
- High school diploma or equivalent
- Post-secondary diploma, certificate, or associate degree in medical billing/coding or health information management
- Certifications (widely recognized):
- Certified Professional Coder (CPC) – from AAPC (American Academy of Professional Coders)
- Certified Coding Specialist (CCS) – from AHIMA (American Health Information Management Association)
- Certified Billing and Coding Specialist (CBCS) – from NHA (National Healthcareer Association)
- Skills required:
- Knowledge of medical terminology, anatomy, and physiology
- Familiarity with coding systems (ICD-10, CPT, HCPCS)
- Understanding of insurance processes, especially Medicare/Medicaid
- Strong attention to detail and analytical skills
- Computer proficiency with EHR and billing software
How to Do Medical Billing and Coding
The process generally follows these steps:
🔹 Step 1: Medical Coding
After a patient encounter, the provider documents the diagnosis and procedures. The coder then:
- Reviews clinical documentation
- Assigns appropriate ICD-10-CM codes for diagnoses
- Uses CPT/HCPCS codes for procedures/services
- Ensures codes match the documentation (compliance is crucial)
🔹 Step 2: Charge Entry
Charges for services are entered into the practice management software based on the codes.
🔹 Step 3: Claim Creation and Submission
A claim is generated electronically and sent to the insurance company (payer). It must include:
- Patient demographics
- Insurance information
- Coded diagnoses and procedures
- Provider credentials and billing information
🔹 Step 4: Claims Adjudication
The insurance payer reviews the claim and either:
- Approves payment
- Partially approves (adjusted amount)
- Denies (requires appeal or correction)
🔹 Step 5: Payment Posting and Patient Billing
Once payment is received:
- Payments are posted in the system
- Any patient responsibility (copay, coinsurance, deductible) is calculated
- Patient statements are generated if needed
🔹 Step 6: Follow-Up and Appeals
Denied or delayed claims are followed up for correction, resubmission, or appeal.
