The ideal candidate will have at least 3 years of direct U.S. healthcare medical billing experience, preferably within a medical practice, clinic, behavioral health organization, ophthalmology practice, dental practice, or other U.S. healthcare setting.

Candidates should be comfortable working across multiple stages of the revenue cycle and should have practical knowledge of medical billing, coding, claims management, denial resolution, AR follow-up, and payer processes.

• Identify and correct billing and coding errors before or after claim submission.
• Manage claim rejections, denials, corrections, appeals, and resubmissions.
• Perform Accounts Receivable (AR) follow-up on outstanding and aging claims.
• Investigate unpaid, underpaid, and incorrectly processed claims and follow up with insurance payers.
• Review EOBs and ERAs and reconcile payments against patient accounts.
• Perform or support payment posting and account reconciliation as required.
• Verify patient eligibility, insurance information, and benefits when required.
• Work with payer portals, clearinghouses, and billing systems to research and resolve claim issues.
• Monitor outstanding AR and take appropriate action to move accounts toward resolution.
• Identify recurring billing, coding, denial, or payment issues and communicate trends to the appropriate team.
• Communicate professionally with insurance companies, providers, patients, and internal teams.
• Maintain accurate billing documentation and follow client-specific processes and compliance requirements.
• Work independently in a remote environment while meeting accuracy, productivity, and turnaround-time expectations.
