Introduction
Medical billing and coding is a critical component of the healthcare industry, as it is responsible for ensuring that healthcare providers receive payments for their services and that patient medical records are accurately recorded and coded. Medical billing and coding is a complex process that requires specialized knowledge and expertise to navigate. In this post, we will answer the common question: how does medical billing and coding work?
Background
The concept of medical billing and coding has been around for over a century. In the early 20th century, medical billing involved handwritten notes and ledgers, which were prone to errors and made the process time-consuming and inefficient. The development of electronic medical records and standardized coding systems, such as the International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes, has revolutionized medical billing and coding. These systems have helped to streamline the billing process, reduce errors, and improve the accuracy of medical records.
According to the Bureau of Labor Statistics, there were approximately 341,600 medical records and health information technician jobs in the United States as of 2020. The employment of medical records and health information technicians is expected to grow by 8% from 2019 to 2029, which is faster than the average for all occupations. This growth is due to the aging population and the increasing demand for healthcare services, which will require more medical billing and coding professionals.
The healthcare industry is also becoming more reliant on technology, which is changing the way medical billing and coding is done. Electronic health records (EHRs) are increasingly being used to store patient medical records, and medical billing and coding professionals must have the knowledge and expertise to navigate these systems. Additionally, advancements in artificial intelligence and machine learning are being used to automate certain aspects of medical billing and coding, further changing the landscape of the industry.
How Does Medical Billing Work?
Medical billing is a complex process that involves the submission of claims to insurance companies and payers to receive payment for healthcare services provided to patients. Inaccuracies or errors in medical billing can lead to delayed payments, denied claims, and even legal action. Therefore, it is important to understand the details of medical billing and how it works in healthcare.
Patient Registration
The medical billing process begins with the registration of the patient. The patient supplies their personal and insurance information, which is used to create a patient record and verify the patient’s eligibility for coverage. According to a study by the Medical Group Management Association (MGMA), patient eligibility errors account for 23% of medical billing errors.
Charge Capture
The healthcare provider documents the services provided to the patient and assigns charges for each service. Charge capture errors can occur when services are not documented or charged for incorrectly, leading to underbilling or overbilling. According to the same MGMA study, charge capture errors account for 15% of medical billing errors.
Medical Coding
Medical coding is the process of translating the services provided to the patient into standardized medical codes, such as ICD and CPT codes. The use of incorrect codes or incorrect code modifiers can lead to claim denials or underpayments. According to a study by the American Medical Association (AMA), 7.1% of all medical claims are denied due to coding errors.
Claim Submission
Once the services are coded and charges assigned, the claim is submitted to the insurance company or payer for payment. Claims can be submitted electronically or by mail, and timely submission is critical to ensure payment is received in a timely manner. According to the AMA, 61% of claims are paid on the first submission, while 30% require follow-up due to errors or denials.
Payment Posting
After the claim is processed, payment is received from the insurance company or payer and posted to the patient’s account. Payments can be made electronically or by check, and the payment must match the billed amount.
Denial Management
If a claim is denied, healthcare providers must investigate the reason for the denial and resubmit the claim with corrections if necessary. Denials can be caused by a variety of factors, including coding errors, missing information, or lack of medical necessity.
How Medical Coding Works?
Medical coding is the process of assigning codes to medical diagnoses, procedures, and services given during patient encounters. Medical codes are used to communicate with insurance companies and to ensure correct payment for medical services.
The two primary coding systems used in healthcare are the International Classification of Diseases (ICD) and Current Procedural Terminology (CPT). The ICD system is used to code diagnoses, while the CPT system is used to code procedures and services.
For example, a patient visit to a primary care physician for a routine checkup may be coded with ICD code Z00.00 (Encounter for general adult medical examination without abnormal findings) and CPT code 99213 (Office or other outpatient visit for the evaluation and management of an established patient).
The medical coding process is an essential part of healthcare that ensures accurate communication between healthcare providers, insurance companies, and government programs. The process involves the translation of medical information into standardized codes using the appropriate coding system. Here is a detailed explanation of the medical coding process:
Patient Encounter
The medical coding process begins with a patient encounter with a healthcare provider. During the encounter, the provider documents the patient’s diagnosis, procedures performed, and services provided.
Diagnosis Coding
Once the diagnosis is documented, the healthcare provider assigns a code using the appropriate coding system. In most cases, the ICD coding system is used to describe diagnoses, symptoms, and abnormal findings. The ICD codes are alphanumeric and provide specific details about a patient’s condition, including its cause, severity, and location. For example, a patient with a diagnosis of hypertension may be assigned ICD code I10 (Essential primary hypertension).
Procedure Coding
After the diagnosis is coded, any procedures or services performed during the encounter are coded. In most cases, the CPT coding system is used to describe medical procedures and services. CPT codes are five-digit numeric codes that describe specific medical procedures and services. For example, a patient visit to a primary care physician for a routine checkup may be coded with CPT code 99213 (Office or other outpatient visit for the evaluation and management of an established patient).
Accuracy and Compliance
Accuracy and compliance with coding regulations are essential to ensure proper payment for medical services rendered. Inaccuracies or errors in coding can result in claim denials, underpayment, or legal action. Healthcare providers must ensure that they are following coding guidelines and regulations set forth by insurance companies and government programs.
Common Medical Billing Errors to Avoid
Medical billing errors can lead to delayed payments, denied claims, and even legal action. Therefore, it is crucial to understand and avoid common billing errors. Here are some common medical billing errors to avoid, along with examples and statistics:
Incorrect Patient Information
Patient information errors occur when incorrect demographic information is entered into the billing system, such as incorrect names, dates of birth, or insurance information. According to a survey by the Medical Group Management Association (MGMA), patient registration errors account for 23% of medical billing errors.
Example: A patient’s insurance policy number is entered incorrectly, resulting in a denied claim.
Incorrect Coding
Coding errors occur when incorrect codes are used to describe medical procedures, diagnoses, or services provided. According to the American Medical Association (AMA), 7.1% of all medical claims are denied due to coding errors.
Example: A healthcare provider bills for a more expensive procedure than was actually performed, resulting in an overpayment.
Unbundling of Services
Unbundling of services occurs when multiple services that should be billed together are separately billed. Unbundling is considered fraudulent billing and can result in legal action.
Example: A healthcare provider bills for a surgical procedure, anesthesia, and post-operative care separately instead of billing for the entire package, resulting in overpayment.
Upcoding
Upcoding occurs when a healthcare provider bills for a higher level of service than was actually provided. Upcoding is also considered fraudulent billing and can result in legal action.
Example: A healthcare provider bills for an office visit as a more complex visit, resulting in overpayment.
To avoid these errors, it is essential to maintain accurate patient records, use the correct codes, and perform regular audits to ensure compliance with billing regulations. Healthcare providers must also stay up-to-date with changes in coding guidelines and insurance policies.
