Billing for Rheumatology Infusions, Labs & Office Visits

Rheumatology practices require specialized billing processes due to the complexity of their services. This often includes infusions of biologic therapies, lab testing to monitor disease markers, and comprehensive office visits. Ensuring accurate billing for these services is critical to maintain a healthy revenue cycle and allow providers to focus on patient care. Here’s an overview of how billing works for rheumatology infusions, labs, and office visits. MaxRemind can help rheumatology practices optimize their billing operations with expert solutions.

Understanding Rheumatology Infusion Billing

Infusions are a core component of rheumatology treatment for diseases such as rheumatoid arthritis, lupus, and other autoimmune disorders. Billing for infusion services involves multiple elements: administration codes, billing for the biologic drugs themselves, and associated supplies.

The initial hour of an infusion is generally billed using CPT codes like 96365 or 96413.
Additional hours are billed with add-on codes such as 96415.
Each infused drug has a unique HCPCS code, such as J9312 for rituximab or Q5103 for infliximab biosimilars.
Proper documentation must include dosage, time, and patient monitoring to meet payer requirements and avoid denials.

Managing Lab Billing in Rheumatology Practices

Lab testing plays a vital role in diagnosis and patient monitoring in rheumatology. Common lab tests include rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibodies, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).

Office Visit Billing for Rheumatology Providers

Office visits are billed using evaluation and management (E/M) codes that correspond to the complexity and time of the visit.

CPT codes 99213 to 99215 are commonly used for established patients.
New patient visits use codes like 99204.
Telehealth visits require specific modifiers and place of service coding.
Documentation must clearly support the chosen E/M level, including history, exam, and medical decision-making.
