How to Start a
Rheumatology Practice

Define the Rheumatology Scope

Rheumatology practices commonly evaluate rheumatoid arthritis, lupus, gout, osteoarthritis, vasculitis, myositis, and spondyloarthropathy. The startup plan should specify what is treated in-house, which procedures are offered, and when patients are referred to orthopedics, nephrology, dermatology, pulmonology, infusion specialists, or hospital care.

A clear scope informs staffing, equipment, payer contracting, protocols, and patient expectations. It also helps the practice design access standards for urgent inflammatory disease, medication reactions, and complex multi-organ presentations.

Credentials, Entity Structure, and Governance

Many rheumatologists complete internal medicine training, rheumatology fellowship, and ABIM certification in rheumatology. Credentialing, enrollment, hospital privileges, and payer participation each have separate requirements and timelines.

Healthcare counsel should review entity structure, corporate practice of medicine restrictions, employment or contractor agreements, and the division between clinical and non-clinical management. Clinical decisions, protocols, prescribing, and patient care must remain under appropriate physician authority.

Build an In-Office Infusion Suite

In-office infusion can support care for biologics such as Remicade, Orencia, and Benlysta when medically appropriate. The suite should have physician-approved orders, pre-infusion screening, vital-sign monitoring, reaction protocols, emergency supplies, trained personnel, and a documented escalation path.

Plan for medication procurement or specialty-pharmacy arrangements, cold-chain requirements, inventory reconciliation, drug wastage documentation, observation workflows, and prior authorization verification before each administration. Leasehold improvements and working capital can materially affect the launch budget.

Prior Authorization for Biologics

Biologics are among the most expensive therapies in medicine. Payers may require records, laboratory results, prior treatment history, diagnosis criteria, dosing information, and appeal support before approving treatment. Delays can interrupt clinically indicated care and create avoidable financial exposure.

Assign ownership for benefits verification, authorization submission, peer-to-peer requests, denials, appeals, and renewal calendars. Track authorization status in the clinical and billing workflow so an infusion is not scheduled without clear coverage and patient responsibility communication.

• ✓Verify benefits before scheduling treatment.
• ✓Maintain standardized clinical documentation packets.
• ✓Track expiration dates and begin reauthorization early.
• ✓Document denial, appeal, and patient communication workflows.

Procedures and Musculoskeletal Ultrasound

Joint aspiration and injection services can be an important component of a rheumatology practice. CPT 20610 is commonly associated with aspiration or injection of a major joint or bursa, but coding must match the actual service, documentation, modifiers, and payer policy.

Musculoskeletal ultrasound can support diagnostic assessment and guide selected injections. Implement competency standards, image retention, procedure notes, infection-control practices, supply management, and coding review before treating ultrasound as a revenue line.

REMS, Medication Safety, and Pharmacy Coordination

Certain biologics and specialty medications may be subject to REMS or product-specific safety requirements. The practice should identify enrollment, counseling, laboratory, monitoring, and documentation duties before initiating a therapy.

Specialty pharmacy coordination should be transparent and compliant. Build a credentialing file for pharmacy partners, define shipment acceptance and storage procedures, and establish a process for recalls, temperature excursions, product complaints, and medication errors.

Rheumatology Coding and Revenue Cycle

Rheumatology billing can include office evaluation and management services, procedure codes such as 20610, infusion administration such as 96413, and applicable drug codes. Each claim must accurately reflect the service provided, time where relevant, medical necessity, drug source, dosage, wastage, modifiers, and payer-specific guidance.

Use certified coding and billing expertise to audit documentation before and after launch. Denial analysis should distinguish authorization failures, coding defects, eligibility issues, and underpayment so the practice can correct root causes.

Financial Model and Startup Costs

A rheumatology practice with infusion capability may require approximately $300,000 to $800,000 in startup capital. Variables include leasehold improvements, infusion equipment, staff, EMR and billing technology, insurance, legal formation, credentialing delays, medication inventory arrangements, and working capital.

The infusion-center model can create recurring administration revenue, but it also creates exposure to drug acquisition costs, delayed payments, denials, and under-authorization. Build conservative cash-flow assumptions and separate clinical quality decisions from financial incentives.

Referral Development and Patient Access

Primary care physicians and orthopedists are essential referral sources, alongside hospitalists, physical therapists, dermatologists, and other specialists. New practices earn referrals through responsive consultation access, clear scheduling, timely notes, reliable care coordination, and respectful co-management.

Avoid referral marketing that creates improper inducement risk. Focus on education, service levels, and communication rather than payment for referrals or promises about treatment selection.

Compliance and Quality Management

A specialty practice needs written policies for privacy, informed consent, medication safety, infusion reactions, adverse events, documentation, billing, and incident response. Periodic chart, coding, authorization, and medication audits help identify patterns before they become systemic.

The medical leadership team should regularly review clinical outcomes, infusion incidents, protocol exceptions, and patient complaints. Continuous improvement is especially important where costly therapies, complex autoimmune disease, and payer controls intersect.

• ✓Review infusion and medication safety events.
• ✓Audit procedure and infusion documentation.
• ✓Monitor authorization and denial trends.
• ✓Update protocols when product, payer, or regulatory rules change.
