Medical billing plays a pivotal role in ensuring that rheumatology practices receive rightful reimbursement for the critical care they provide to patients with autoimmune and musculoskeletal disorders.

In rheumatology, where conditions can be complex, and treatments often involve various services, accurate billing is necessary for financial stability and high-quality patient care. However, navigating the intricacies of medical billing can be a daunting task.

This article will break down the common hurdles rheumatology practitioners face in billing. From coding errors to ever-evolving regulations and the challenges of proper documentation, we’ll explore the obstacles hindering the revenue cycle. 

But fret not, for we will also get involved in effective strategies and solutions to help you overcome these obstacles. Whether it’s investing in cutting-edge billing technology, training your staff, or considering outsourcing, we’ve got you covered.

Challenges In Rheumatology Medical Billing

Medical billing in rheumatology can be complex due to the unique nature of services provided and the evolving healthcare landscape. Here are some common challenges in rheumatology medical billing:


  • Coding Complexity: Rheumatology involves a wide range of conditions and treatments, each with specific codes for billing. Accurate coding is crucial to ensure proper reimbursement.
  • Frequent Regulatory Changes: Medical billing regulations, including codes and billing rules, often change. Staying up-to-date with these changes can be challenging.
  • Documentation Requirements: Rheumatology services require detailed documentation to support the medical necessity of procedures. Incomplete or inaccurate documentation can lead to claim denials.
  • Prior Authorization: Many rheumatology treatments and medications require prior authorization from insurance companies. Navigating this process can be time-consuming and prone to delays.
  • Claim Denials: Claims may be denied for various reasons, including coding errors or lack of medical necessity documentation. Managing and appealing denials can be labor-intensive.
  • Complex Procedures: Rheumatologists often perform complex procedures, which may have multiple components billed separately. Coordinating these components can be challenging.
  • Collections: Collecting patient payments, especially for high-cost treatments, can be challenging. Developing effective collection strategies is important.
  • Technology Integration: Efficient billing often relies on medical billing software and electronic health records (EHR) systems. Integrating these technologies seamlessly can be a hurdle.
  • Outsourcing Considerations: Deciding whether to handle billing in-house or outsource it to a medical billing service can be a significant decision with its challenges.



Common Codes For Rheumatology Medical Billing – CPT And ICD-10 Codes And Expected Errors


Common codes for rheumatology medical billing are typically related to specific diseases, conditions, and procedures. Here are some common CPT (Current Procedural Terminology) codes and ICD-10 (International Classification of Diseases, 10th Edition) codes used in rheumatology, along with potential errors that can occur due to a lack of coding expertise:

Common CPT Codes in Rheumatology

  • 99203-99205: Office or outpatient visit codes for new patients. Errors may occur if the visit’s complexity level needs to be documented accurately.
  • 99213-99215: Office or outpatient visit codes for established patients. Errors may occur if the documentation does not support the level of service billed.
  • 20600: Arthrocentesis, aspiration and/or injection, small joint or bursa (e.g., fingers, toes) without ultrasound guidance.
  • 20604: Arthrocentesis, aspiration and/or injection, small joint or bursa (e.g., fingers, toes); with ultrasound guidance, with permanent recording and reporting.
  • 20605: Arthrocentesis, aspiration and/or injection, intermediate joint or bursa (eg, temporomandibular, acromioclavicular, wrist, elbow or ankle, olecranon bursa); without ultrasound guidance.
  • 20606: Arthrocentesis, aspiration and/or injection, intermediate joint or bursa (eg, temporomandibular, acromioclavicular, wrist, elbow or ankle, olecranon bursa); with ultrasound guidance, with permanent recording and reporting.
  • 20610: Arthrocentesis, aspiration, and injection; major joint or bursa (e.g., shoulder, hip, knee joint, subacromial bursa) without ultrasound guidance. Errors can occur if the joint or bursa aspirated/injected is not specified.
  • 20611: Arthrocentesis, aspiration and/or injection, major joint or bursa (eg, shoulder, hip, knee, subacromial bursa); with ultrasound guidance, with permanent recording and reporting.
  • 96372: Therapeutic, prophylactic, or diagnostic injection (specify substance or drug); subcutaneous or intramuscular. Errors may arise if the specific drug administered needs to be documented.
  • 81000-81003: Urinalysis codes. Errors can occur if the reason for the urinalysis needs to be documented or if the wrong code is chosen based on the test’s complexity.
  • 71010-71020: Chest X-ray codes. Errors may occur if the type and number of views need to be specified in the documentation.
  • 96401: Injection and Intravenous Infusion Chemotherapy administration, subcutaneous or intramuscular; non-hormonal anti-neoplastic.

Common ICD-10 Codes in Rheumatology

  • M05.9-M06.9: Rheumatoid arthritis codes. Errors can occur if the subtype or laterality needs to be documented correctly.
  • M32.0-M32.9: Systemic lupus erythematosus codes. Errors may arise if specific organ involvement needs to be documented.
  • M45.0-M45.9: Ankylosing spondylitis codes. Errors can occur if the site or severity needs to be documented accurately.
  • M79.7: Fibromyalgia. Errors may arise if fibromyalgia is not documented when it is a significant part of the patient’s condition.

Rheumatology Major Mod: XU, LT, RT, 50, 59, 25

  • Modifier -25: This modifier tells the insurance company that an evaluation and management (E/M) visit was necessary on the same day as a procedure, and there’s documented proof supporting the need for both. In simpler terms, it shows that a doctor’s visit and a medical procedure were necessary and distinct on the same day.
  • Modifier -50: This modifier can be used to show that a procedure was performed on both sides of the body. For example, if you had a procedure on both your left and right arms, you might use this modifier on the second arm’s procedure.
  • Modifiers -LT and -RT: These modifiers specify whether a procedure was done on the left side (-LT) or the right side (-RT) of the body.
  • Modifier -59: This is used when you have two procedures in different areas of your body during the same visit. It indicates that these procedures are separate and not related.
  • Modifier -XU: This modifier is for unusual non-overlapping services. You should check with your insurance company to see if they allow either -59 or -XU for a particular situation.
  • For billing purposes, you might see a claim like this: 99214-25 (E/M visit), 96361-XU or -59 (procedure), 96413 (chemotherapy), 96415 (another chemotherapy), and J1745 x 20, J7050 (medications).
  • The modifier -25 indicates that the E/M visit and procedure were separate and necessary for medical reasons. Modifier -59 or -XU shows that two different body areas received procedures during the same visit. This way of coding follows the guidelines set by the American Medical Association (AMA).


Expected Errors Due to Lack of Coding Grip

  • Under coding: If coders are unfamiliar with the full spectrum of codes available for a condition or service, they may under code, resulting in lower reimbursement than deserved.
  • Overcrowding: Conversely, a lack of coding expertise can lead to overcrowding, where providers bill for services or levels of complexity need to be supported by the documentation. This can lead to audits and potential penalties.
  • Incorrect Code Selection: Selecting the wrong code due to unfamiliarity with the code set or the specific criteria for code selection can lead to claim denials or incorrect billing.
  • Incomplete Documentation: Lack of understanding of coding requirements can result in incomplete documentation, which may not adequately describe the patient’s condition or the services provided.
  • Failure to Capture Specifics: In rheumatology, many conditions have specific codes based on laterality, subtype, and severity. Errors may occur if these specifics need to be documented or coded correctly.

Rheumatology Medical Billing In Relation With RVU

The connection between Rheumatology Medical Billing and RVU (Relative Value Unit) lies in how RVUs are used to determine the reimbursement rates for medical services provided by rheumatologists. The Total RVU consists of three components: Physician Work RVU, Practice Expense RVU, and Malpractice Expense RVU. Here’s how these components are related to rheumatology medical billing:

Physician Work RVU

This component of the Total RVU reflects the physician’s effort, time, and skill required to perform a specific medical service or procedure. In rheumatology, services can vary in complexity, such as evaluating and managing patients with autoimmune diseases, conducting joint injections, or interpreting complex diagnostic tests. The Physician Work RVU for each CPT code in rheumatology accounts for the unique nature of these services. 

●       Connection to Billing: The Physician Work RVU plays a critical role in determining the reimbursement for a specific service in rheumatology. The higher the RVU for a service, the more reimbursement a rheumatologist can expect when billing for that service.


Practice Expense RVU

The Practice Expense RVU covers the overhead costs associated with running a medical practice, including rent, staff salaries, equipment, and supplies. This component is relevant for rheumatologists because their practice expenses can vary based on factors like the complexity of procedures performed, the need for specialized equipment, and the cost of drugs and biologics.

●       Connection to Billing: The Practice Expense RVU indirectly affects the overall reimbursement for a rheumatologist’s services. Higher Practice Expense RVUs may indicate a need for higher reimbursement rates to cover practice costs, which can influence billing strategies and negotiations with payers.

Malpractice Expense RVU

Malpractice Expense RVUs are related to the cost of malpractice insurance. In rheumatology, where patients may require long-term management and medications with potential side effects, the cost of malpractice insurance can vary.

●       Connection to Billing: While the Malpractice Expense RVU directly impacts the Total RVU, it may not be as directly relevant to the day-to-day billing decisions for rheumatologists. However, it contributes to the overall RVU calculation and, therefore, the final reimbursement.
