Experienced Medical Biller – Rheumatology & Infusion Services
Location: San Antonio, Texas
Schedule: Monday–Friday | 8:00 AM – 5:00 PM
Position Type: Full-Time
We are seeking a highly experienced Medical Biller with a strong background in rheumatology and infusion billing to join a growing medical practice expanding into the San Antonio market. This position will support one provider initially, with the opportunity to grow alongside the practice.
This role is ideal for a professional who understands the nuances of specialty billing, values accuracy and compliance, and wants to be part of a practice that treats its team as long-term partners—not replaceable staff.
Key Responsibilities
- Handle end-to-end medical billing for rheumatology and infusion services
- Submit, track, and follow up on insurance claims with commercial carriers, Medicare, and Medicaid
- Manage infusion-related coding, billing, and reimbursement, including biologics and specialty medications
- Work confidently within eClinicalWorks (eCW) for charge entry, claims management, and payment posting
- Identify and resolve denials, underpayments, and coding issues efficiently
- Ensure compliance with payer rules, medical necessity requirements, and documentation standards
- Coordinate with clinical staff to resolve billing discrepancies and optimize revenue cycle performance
Required Qualifications
- Proven experience in rheumatology billing (required)
- Hands-on experience with infusion billing practices (required)
- Strong working knowledge of eClinicalWorks billing module
- Solid understanding of CPT, ICD-10, HCPCS, and modifier usage relevant to rheumatology and infusions
- Ability to work independently with minimal supervision
- High attention to detail, organization, and follow-through
- Professional, reliable, and discreet with patient and financial information
What We Offer
- Competitive pay, commensurate with experience
- Health insurance benefits
- Retirement plan options
- Performance-based bonuses
- Stable Monday–Friday schedule (no nights, no weekends)
- A respectful, professional work environment
- Opportunity to grow with a practice that is actively expanding
Why This Role Stands Out
This is not a high-volume, chaotic billing mill. You’ll be working closely with a single provider in a practice that values precision, ethics, and long-term growth. Your expertise will matter, your input will be respected, and your performance will be rewarded.
