Medical billing codes are crucial elements used for processing medical and healthcare services. It helps hospitals and insurance companies identify the treatments and procedures a patient receives and charge for them appropriately. 

The codes are used by insurance companies to reimburse healthcare facilities. They also help researchers study trends in procedures and treatments. 

Most companies use medical billing software like NYBillPro to automate coding for these transactions. Software makes it easy for providers to find and use the correct codes for the right treatments. Because these codes are very extensive and detailed, certification is required to become a medical coder.

Let’s explore the most common medical billing codes used in healthcare facilities. 

Types of Medical Coding 

There are five types of medical coding used in healthcare. These classifications depend on the treatments or procedures given to the patient. 

Current Procedural Terminology (CPT)

This type of coding is used for reporting medical services. It increases the efficiency and accuracy for insurance providers to identify the treatments provided.

Developed by the American Medical Association (AMA), it is used by healthcare providers to bill insurance companies. 

International Classification of Diseases (ICD-11)

This coding is the World Health Organization’s (WHO) diagnostic classification system used to classify diseases. It can be used to study the consequences and causes of illness and death. 

The ICD is used in the healthcare industry to report on diseases and their related health conditions. These codes ensure that comparing and monitoring global health is standardized across all regions and countries. This is the 11th version of this coding resource. 

ICD-10 Clinical Modification (CM)

The ICD-10 is the 10th version of the coding resource. They are used to classify mortality data based on death certificate information. 

ICD-10 Procedure Coding System (PCS)

These codes are used to support procedures, including data collection, electronic health records, payment, and billing. This is very important for patients receiving Medicare and Medicaid. 

The Healthcare Common Procedure Coding System (HCPCS)

This system of codes describes medical procedures and supplies used for each patient. The Centers for Medicare and Medicaid Services (CMS) developed this system to standardize billing payments. 

This system has two parts: Level I and Level II.  Level II identifies supplies, services, and products that are not included in the CPT system. These include transport or ambulance services, medical equipment, orthotics, and other equipment used outside a clinic or healthcare facility.

The Benefits of Medical Coding 

The Benefits of Medical Coding 

The United States uses medical billing codes to improve the efficiency and accuracy of the healthcare system. Because citizens have very limited public health options, insurance companies and healthcare facilities work together to provide the best care for patients.

Medical billing and coding companies use these codes to standardize the treatments and procedures given to patients. This makes it easier for insurance companies to identify the treatments or procedures patients are entitled to under their policies. 

Here are the benefits of using medical billing coding systems:

Standardization

These systems use a standard code or language that all parties can understand. This minimizes misunderstandings and miscommunications and increases accuracy in billing and payment processes. 

Data Collection and Analysis

Using medical billing codes helps researchers and analysts track trends in the healthcare industry. They can observe data patterns regarding specific treatments and diseases. This helps medical experts make data-driven decisions for public health policies and healthcare delivery. 

Prevention of Fraud

Using the correct medical billing codes prevents fraud within the payment process. The codes include specific guidelines and classifications that define particular materials, treatments, and supplies used for every transaction. These rigid data sets ensure accuracy on all fronts.

Payment and Reimbursement

Insurance companies use medical billing codes to calculate the amount they need to pay healthcare facilities for specific treatments. Accurate coding helps all parties review these calculations and ensure timely and correct payments.

Efficiency

Medical codes also make the payment processes more efficient. Since the language and codes used are standardized, it reduces administrative costs, avoids duplicates, limits errors, and speeds up each step. 

Popular Medical Billing Codes

Under this code, patients likely have a progressing illness or acute injury. Their circumstances require complex medical management or a surgical procedure. 

Medical Billing Code 99213

This code describes a patient’s healthcare office visit in terms of evaluation or management. Visits are only between 20 and 29 minutes, and no more. 

This code implies a visit from a patient with a chronic but stable illness or an acute but simple injury. Using this code also implies that the decision-making needed for treatment is relatively low level. The treatment and medical history provided are appropriate for the patient’s condition.

Medical Billing Code 99284

This code is for emergency department visits or unscheduled patient visits that require urgent medical care. It defines emergency departments as hospital-based facilities that are open 24 hours. 

It does not differentiate between new or current patients that require immediate or urgent medical attention. The patient’s condition should have a high level of severity and must include the following components:

  • Detailed history

  • Medical decision (moderate level)

Medical Coding is a Crucial System

Medical Coding is a Crucial System

The medical and healthcare industry has many stakeholders. It does not just involve hospitals, patients, and families. Insurance companies, third-party service providers, suppliers, and government programs are all crucial players that help provide the best health services to those who need them. 

And to provide the best possible medical service, these distinct organizations need a standardized system to communicate and identify the specific service and procedure a patient needs. 

This is where medical coding comes in. These codes ensure that the services are accurately described and thoroughly documented. It specifies the procedures and treatments that a health facility provides a patient, the medications given, and the amount that must be paid.

Accurate medical coding ensures that patients are billed correctly and fairly, and that insurance providers will pay the reimbursements according to the list of codes supplied by the healthcare provider. 

It Pays to Know the Right Medical Billing Codes

The next time you go to your doctor, or receive an invoice from the hospital, check the medical billing codes. They specify your treatments, health condition, and the length of your evaluation or treatment. 

Medical billing software like BillPro uses these codes for insurance claims, process payments, and reimbursements. So it pays to streamline your billing system and improve your efficiency with the right medical billing software.
