Revenue code is pivotal in medical billing in specifying the department, service location, or type of service rendered in a patient visit. Revenue codes, in conjunction with CPT and HCPCS codes, articulate where and which hospital cost center the services were delivered. This guide details the definition of a revenue code in medical billing, how revenue codes are applied in claims, the definition and regulation of revenue codes by CMS, and the reasons for their importance in securing reimbursement. Also, it discusses hospital and outpatient revenue codes, pharmacy and radiology revenue codes, revenue codes by room and board classification, and providers’ billing-related revenue code errors. Lastly, it describes how A2Z Billings assists providers in maintaining compliance and the appropriate use of revenue codes.
Introduction: Why Revenue Codes Matter in Medical Billing
Medical billing is more than just the use of procedure and diagnosis codes. Specifically, for institutional claims, revenue codes become critical, as they specify the service rendered and the billing department. Revenue codes serve to assist payers in understanding how charges are classified for reimbursement determinations.
Due to a lack of understanding of revenue codes in medical billing, claims can be denied, underpaid, or audited, even if everything else, such as the CPT and diagnosis codes, are accurate. Revenue codes are vital for hospitals, outpatient facilities, skilled nursing facilities, and other types of institutional providers.
What Is a Revenue Code in Medical Billing?
A revenue code refers to a 4-digit, numeric code used in institutional claims to determine the division or cost center in which a service was performed. Revenue codes cannot be used to determine the clinical service rendered, but can only help in classifying charges by the location or type of service rendered.
For example, revenue codes can be used to determine the difference between the emergency room, operating room, radiology, pharmacy, room and board, and outpatient clinic services. These codes are also essential for the correct processing of institutional claims by Medicare, Medicaid, and other commercial payers.
What Are Revenue Codes in Healthcare?
Revenue code application in healthcare billing happened primarily in the completion of the UB-04 (CMS-1450) claims, and not in the CMS-1500 forms. They are a necessity for hospitals, outpatient departments, rehab facilities, and all other types of institutional providers.
Revenue codes in different aspects help the payers in the allotment of costs, in the imposition of appropriate reimbursement policies, and the examination of patterns in expenditures in the healthcare system. Revenue codes are a necessity for proper processing of institutional claims.
Revenue Codes vs CPT and HCPCS Codes
While Revenue Codes and CPT/HCPCS codes serve different purposes, they function together on a claim. CPT and HCPCS codes detail a specific service or supply provided, whereas revenue codes indicate which billing department the charge falls under.
Consider a scenario where a radiology procedure is billed using a CPT code, while the revenue code clarifies which one of the following was used: diagnostic radiology, nuclear medicine, or any other imaging department. Both codes must match in order for the claim to get paid.
Revenue Codes Defined by CMS
The Centers for Medicare & Medicaid Services (CMS) maintains the standardization of revenue codes and applies them to Medicare and Medicaid as well as to many private insurers.
CMS revenue codes are organized in terms of various service categories (e.g., room and board, laboratory, radiology, pharmacy, and therapy services). For Medicare, the proper and accurate application of CMS revenue codes is critical.
Hospital Revenue Codes Explained
In a hospital context, revenue codes indicate various departments or service areas. These codes are applicable to both inpatient and outpatient services and assist in the determination of payment methods, e.g., DRGs or APCs.
Hospital revenue codes must correspond with the documented services in the medical record. If procedures and revenue codes do not match, audits or payment reductions can occur.
Outpatient Revenue Codes and Their Role
Revenue codes for outpatient services apply when a patient does not receive an inpatient admission. These codes are critical to hospital outpatient departments, ambulatory surgery centers, and clinics.
Outpatient revenue codes serve to position Medicare with the appropriate APC groupings and reimbursement levels. Careful documentation promotes adherence to the outpatient prospective payment system.
Radiology Revenue Codes in Medical Billing
Radiology revenue codes are applicable for each category of imaging service, including X-ray, CT, MRI, and nuclear medicine studies. These codes carve out diagnostic imaging from therapeutic radiology services.
Radiology revenue codes must reference the corresponding imaging CPT codes for payment to occur. Insufficient or erroneous radiology revenue coding can lead to claim denial or reimbursement at less than the full amount due.
Understanding Pharmacy and Supply Revenue Codes
Pharmacy revenue codes and related supplies cover the billing of medications, IV solutions, and other supplies utilized during the course of patient care. These codes inform payers whether the prescribed medications are available as inpatient drugs, outpatient drugs, or under the pharmacy benefit.
Correct revenue code application is critical for costly drugs and infusion services to prevent financial loss due to underpayment.
Room and Board Revenue Codes
Room and board revenue coding is done based on the type of room and level of care for inpatient accommodation charges. Different coding is done for routine care, intensive care, and special units.
Careful coding of these elements ensures proper assignment of a Diagnostic Related Group and subsequent payment. Inaccurate coding can result in a large discrepancy for the payment determination involving the inpatient services.
Therapy and Rehabilitation Revenue Codes
The same coding for revenue is also applicable for services relating to physical, occupational and speech therapy. This coding assists in the differentiation of therapy departments and supports correct billing to the therapy payment regulations.
For the sites that are billing under therapy caps and subject to a utilization review, therapy revenue coding is very important.
Common Revenue Codes Used in Medical Billing
Because of the commonality of certain services, e.g. emergency services, lab services, services in radiology and the pharmacy, certain revenue codes are used frequently in institutional claims.
Knowledge of these revenue codes that are used frequently in the billing process aids in identifying billing errors more effectively and establishing uniformity in the claims process.
How Revenue Codes Affect Medical Claims Processing
The main function of revenue codes is the categorization of services. Medical claims are also processed based on revenue codes. Insurers also use these codes to analyze bundles, payment rules, and coverage for services.
Services may be denied for valid clinical reasons because of missing or incorrect revenue codes.
Revenue Codes and Medical Claims Denials
Many claim denials result from the selection of inappropriate revenue codes rather than the absence of an appropriate procedure. Claims may be denied by payers if the revenue code is inconsistent with the corresponding billed CPT or HCPCS code.
In outpatient hospital billing and emergency department claims, revenue code discrepancies abound.
Revenue Codes and Compliance Risks
Inappropriate revenue coding may result in audits, recoupments, and other compliance-related penalties. Because CMS monitors institutional billing closely, inconsistent or inappropriate use of revenue coding may result in scrutiny.
Compliance is an ongoing effort that includes regular education, internal audits, and an awareness of CMS billing updates.
Revenue Code Lists and Standardization
To promote system-wide consistency in the use of revenue codes, CMS publishes updates. While the majority of revenue codes are the same across systems, there are some differences that are specific to individual payers.
Billing staff should be familiar with the updates to minimize the use of antiquated or incorrect revenue codes.
Revenue Codes and Entity Codes in Medical Billing
Some clients mistake revenue codes used in a bill with entity codes. While revenue codes are used to explain what type of services a bill has, entity codes are used to specify which provider, facility, or supplier is billed on service delivery.
Knowing the difference helps avoid mistakes when submitting a bill.
Common Revenue Code Billing Errors
Most revenue code errors happen when a department is falsely mapped, charge descriptions are not updated, or no procedural codes are given or are related to the service. Such errors can result in revenue loss or payments that won’t be collected. To lessen these mistakes, a constant review of claims and audits of the system is necessary.
