Accounts Receivable Specialist

Lumary

14d • Hybrid

About The Position

The Accounts Receivable Specialist is a vital member of the Lumary RCM Department, responsible for owning the collection of outstanding ABA claims and driving down aged receivables. This is a collections-focused role for a tenacious problem-solver who treats every unpaid or underpaid claim as a case to investigate and resolve. You will spend the majority of your time pursuing payers, working aged AR, appealing denials, and chasing down the root cause of why claims aren't paying, then fixing it. While the primary focus is collections and AR resolution, you will also handle a limited amount of upfront claim submission and payment posting as needed to support the team. Your real strength is investigation: digging into payer behavior, spotting patterns across denials and underpayments, and pursuing every dollar owed through to resolution. This role reports to the Director, Revenue Cycle Management.

Requirements

• Collections or accounts receivable experience is required.
• You have a track record of working aged AR, denials, and appeals - ideally in a medical billing or healthcare RCM setting.
• Strong investigative ability. You dig into the details, ask the right questions, and don't stop until you've found why a claim isn't paying and resolved it.
• Strong understanding of the medical claim lifecycle, denials management, and payer reimbursement processes.
• Confident and persistent in payer follow-up and appeals, with excellent documentation and follow-through.
• Familiarity with ERA/EOB processing and electronic claim submissions.
• Prior experience in Medicaid billing.
• The successful candidate will be required to undergo employment screening checks relevant to the healthcare industries we serve.
• We are currently only accepting applications from candidates who are located in the United States and are authorized to work for any employer without sponsorship.
