Job Description


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.
