Medical Billing Coding For Dummies

1. Coding and Billing: Two Distinct Yet Intertwined Roles

Coding versus Billing: They Really Are Two Jobs.

Coders and Billers. Medical coding and billing are often referred to as a single job, but they are distinct. Coders translate healthcare providers' documentation into standardized codes, while billers use these codes to create and submit claims for reimbursement.

Coder Responsibilities. Coders analyze medical records, assign appropriate diagnosis (ICD) and procedure (CPT) codes, and ensure documentation supports the codes selected. They must stay updated on coding guidelines and regulations.

Biller Responsibilities. Billers prepare and submit claims to insurance companies, follow up on unpaid claims, and handle patient billing inquiries. They need to understand payer requirements and billing formats. Both roles are essential for revenue cycle management.

2. Compliance is Key: Adhering to Regulations and Ethical Standards

Being in compliance basically means an office or individual has established a program to run the practice under the regulations as set forth by the U.S. Office of Inspector General (OIG).

Regulatory Framework. Compliance involves adhering to regulations set by the Office of Inspector General (OIG) and the Health Insurance Portability and Accountability Act (HIPAA). These regulations aim to prevent fraud, abuse, and protect patient privacy.

HIPAA's Impact. HIPAA establishes national standards for the use and disclosure of health information, granting patients rights regarding their medical records. It requires providers to inform patients of their privacy practices and secure their consent for information disclosure.

Consequences of Non-Compliance. Violations of HIPAA and other regulations can result in significant fines, penalties, and even imprisonment. Therefore, medical billers and coders must prioritize compliance in their daily tasks.

3. Mastering Medical Terminology: The Language of Healthcare

Insurance companies are usually the parties responsible for paying the doctor or other medical provider for services rendered.

Decoding Medical Terms. Medical terminology is the language used to describe illnesses, injuries, conditions, and procedures. Most medical terms are formed from Greek and Latin prefixes and suffixes.

Prefixes and Suffixes. Prefixes indicate the beginning segment of a word, often relating to a body part or area. Suffixes describe a condition or action. Understanding these components is crucial for deciphering medical terms.

Applying Terminology. By combining prefixes and suffixes, you can understand the meaning of complex medical terms. For example, "arthro-" (joint) + "-itis" (inflammation) = "arthritis" (inflammation of the joint). A solid foundation in medical terminology is essential for accurate coding.

4. Proving Medical Necessity: Justifying Services for Reimbursement

Before a payer (such as an insurance company) will reimburse the provider, the provider must show that rendering the services was necessary.

Defining Medical Necessity. Medical necessity refers to the requirement that any procedures performed are necessary to diagnose or treat a medical condition while maintaining an acceptable standard of care. Payers will only reimburse for medically necessary services.

Linking Diagnosis and Procedure Codes. To prove medical necessity, the coder must ensure that the diagnosis code supports the treatment given. The diagnosis code must justify the procedure being billed.

Evaluation and Management Codes. Evaluation and Management (E&M) codes are used for office visits and consultations. The level of service billed must be supported by the documentation, including patient history, physical examination, and medical decision-making.

5. Navigating the Payer Landscape: Understanding Insurance Types

Most providers have contracts with multiple commercial payers (basically insurance companies), as well as government payers, such as Medicare.

Commercial Insurance. Commercial insurance includes private insurance carriers, such as Preferred Provider Organizations (PPOs), Health Maintenance Organizations (HMOs), and Point of Service (POS) plans. Each type has specific rules regarding coverage and reimbursement.

Government Payers. Government payers include Medicare (for the elderly and disabled), Medicaid (for low-income individuals), and Tricare (for military members and their families). These programs have their own coding and billing guidelines.

Third-Party Administrators. Third-party administrators (TPAs) handle claims processing for employers who self-insure their employees. TPAs either operate as a network or access networks to price claims.

6. Certification: A Must-Have for Career Advancement

To score a job as a biller and coder, you must get certified by a reputable credentialing organization such as the American Health Information Management Association (AHIMA) or the AAPC (formerly known as the American Academy of Professional Coders).

AAPC and AHIMA. The AAPC (American Academy of Professional Coders) and AHIMA (American Health Information Management Association) are the two primary credentialing organizations. Certification demonstrates proficiency and commitment to quality.

AAPC Certifications. AAPC offers Certified Professional Coder (CPC) credentials, focusing on physician offices and outpatient hospital-based coding. AAPC also offers specialty certifications.

AHIMA Certifications. AHIMA offers Certified Coding Associate (CCA) and Certified Coding Specialist (CCS) credentials, focusing on inpatient and outpatient hospital-based coding. AHIMA also offers specialty certifications.

7. Education and Training: Building a Solid Foundation

Most billing and coding programs get you up and running in a relatively short amount of time, often less than two years.

Training Program Essentials. A solid medical coding and billing program provides training in human anatomy and physiology, medical terminology, medical documentation, medical coding, claims filing, and medical insurance.

Educational Options. Training programs are available at community colleges, technical schools, and online. Each option has its advantages and disadvantages in terms of cost, time commitment, and curriculum.

Choosing the Right Program. When selecting a program, consider your career goals, the type of certification you want, and the program's accreditation and reputation. Avoid diploma mills that promise quick certification without adequate training.

8. The Claims Process: From Encounter to Payment

Claims processing refers to the overall work of submitting and following up on claims.

Patient Encounter. The claims process begins with the patient encounter, where initial paperwork is completed and services are provided. The provider documents the services rendered.

Coding and Billing. The coder abstracts billable codes from the documentation, and the biller enters the codes into billing software and submits the claim to the payer. The biller then tracks the claim from submission to payment.

Claim Adjudication. The payer reviews the claim for medical necessity, coverage, and contract compliance. If the claim is approved, payment is issued. If the claim is denied, the biller must follow up and appeal the denial.

9. Ethical Practice: Maintaining Integrity and Protecting Stakeholders

With this responsibility comes great power, and that power must be treated with respect and integrity.

Professional Conduct. Medical billers and coders must maintain a high level of professionalism in all interactions with patients, payers, and colleagues. This includes being courteous, respectful, and honest.

Confidentiality. Protecting patient confidentiality is paramount. Medical billers and coders must adhere to HIPAA regulations and safeguard patient information from unauthorized access or disclosure.

Accurate Coding. Accurate coding is essential for ethical billing practices. Medical billers and coders must avoid upcoding, downcoding, and unbundling procedures for the sole purpose of increasing reimbursement.

10. Staying Current: Adapting to Industry Changes and Technological Advancements

As a biller/coder, you use the ICD every day.

ICD-10 Transition. The transition from ICD-9 to ICD-10 is a significant change in the medical coding industry. ICD-10 contains more codes and requires greater specificity in documentation.

Continuing Education. Medical billers and coders must participate in continuing education to stay current on coding guidelines, regulations, and technological advancements. This includes earning continuing education units (CEUs) and attending workshops and conferences.

Embracing Technology. Medical billing and coding is increasingly reliant on technology. Medical billers and coders must be proficient in using billing software, electronic health records (EHRs), and other technological tools.
