Current Procedural Terminology (CPT) codes are essential tools that healthcare providers use to track and report medical services and procedures. These codes ensure accuracy and efficiency in medical billing and reporting by assigning specific codes to each service or procedure.
CPT codes play a crucial role in determining reimbursement rates, as insurers use these codes to calculate payments to providers. This standardization across all providers and payers simplifies the billing process and helps minimize errors.
What Are CPT Codes?
CPT codes are numerical identifiers assigned to medical services or procedures. Healthcare providers use these codes for reporting, billing, and administrative purposes. While some CPT codes are rarely used, others are quite common. For example, codes 99213 and 99214 are frequently used for general office visits, addressing new concerns or following up on existing issues.
The American Medical Association (AMA) is responsible for developing, maintaining, and updating CPT codes, which are used in over 60 countries. As healthcare evolves, these codes may be revised, with new codes introduced and obsolete ones removed. Thousands of CPT codes are updated annually.
Types of CPT Codes
CPT codes consist of five digits, with most being numerical, though some include letters. The codes are categorized as follows:
- Category I: Procedures, services, devices, and drugs (including vaccines).
- Category II: Performance measures and quality of care, such as patient follow-up.
- Category III: Emerging technology services and procedures, often temporary as the services are still new.
PLA Codes: Used specifically for lab testing.
Examples of CPT Codes
- Here are a few examples of CPT codes in use:
- 99397: Preventive exam for individuals over 65.
- 90658: Flu shot administration.
- 90716: Chickenpox vaccine (varicella) administration.
- 12002: Stitches for a 1-inch cut on the arm.
- 87635: COVID-19 test.
How CPT Codes Are Used
CPT codes have a direct impact on patient costs for medical care. Providers, hospitals, and other medical facilities are meticulous in their coding practices, often employing professional medical coders or outsourcing to ensure accuracy.
Initial Coding: During a visit, healthcare providers or their staff list applicable CPT codes. In facilities using electronic health records (EHR), these codes are recorded in the system, typically linked to service names.
Verification and Submission: Medical coders and billers review the records to ensure the correct CPT codes are used before submitting the list of services to the insurer or payer, often digitally, though some submissions are still done by mail or fax.
Claims Processing: Insurers use CPT codes to process claims, determining payment amounts to providers and the patient’s out-of-pocket costs.
Research: Health insurers and government officials analyze coding data to predict healthcare costs and track medical care trends, aiding in planning and budgeting for programs like Medicare and Medicaid.
Where You’ll See CPT Codes
CPT codes appear in various healthcare documents, including:
Discharge Paperwork: After an appointment or discharge, a summary of services and their corresponding codes is provided. These five-character codes are usually CPT codes, though ICD codes indicating diagnoses may also be present.
Bills: Medical bills list the services received, each matched with a five-digit CPT code.
Explanation of Benefits (EOB): These statements from insurers detail the costs covered on the patient’s behalf, with each service paired with a CPT code.
Matching CPT Codes to Services
While CPT codes are essential for understanding medical bills, they are copyrighted by the AMA, which charges for access to the full list. However, the AMA allows consumers to look up CPT codes through their website, offering five free searches per day after registration. Alternatively, patients can contact their healthcare provider or insurer for assistance in matching CPT codes to services.
Preventing Incorrect Coding
Understanding CPT codes can help ensure accuracy in medical billing, as errors are common and can significantly impact costs. Simple mistakes, like typographical errors, or fraudulent practices, like “upcoding” or “unbundling,” can lead to higher bills. Patients are encouraged to review their bills and EOBs carefully and to contact their provider’s billing department if something doesn’t add up.
Limitations of CPT Codes
While CPT codes standardize the billing process, they don’t guarantee uniform payment rates for the same service across different providers, as payments depend on individual contracts between providers and insurers.
HCPCS Codes
CPT codes differ from the Healthcare Common Procedure Coding System (HCPCS) codes, which are used for billing Medicare, Medicaid, and other third-party payers. HCPCS codes are divided into two levels:
- Level I: Based on CPT codes, used for services and procedures by healthcare providers.
- Level II: Cover services and procedures not performed by healthcare providers, such as medical equipment and supplies.
Summary
CPT codes are critical identifiers in healthcare, ensuring a uniform system for reporting services. Providers use these codes to communicate with insurers, who then reimburse based on the codes. Patients can find these codes on their discharge paperwork, bills, and benefit statements. Understanding and reviewing these codes can help prevent billing errors and ensure accurate charges.
