Medical Biller and Credentialing Specialist

We are seeking an experienced, leadership-minded Virtual Medical Biller & Credentialing Specialist to support a busy mental health clinic led by Dr. Mann. In this critical revenue-recovery and operational oversight role, you will initially audit and monitor the output of an external, third-party medical billing company whose contract runs through April 2027. With approximately 90 days of pending billing and 500+ outstanding patient encounters, your mission is to identify claim bottlenecks, resolve billing errors, hold the external agency accountable, and directly recapture revenue for the practice.

In addition to revenue cycle management, you will lead and execute provider insurance credentialing across commercial, Medi-Cal, and Medicare payors. The ideal candidate possesses 3+ years of U.S. medical billing, coding, and credentialing experience , background managing or independently leading credentialing workflows, hands-on mastery of major payor portals (with Availity as top priority , alongside Optum and Medicare), and direct experience in a mental/behavioral health setting . This position starts as a part-time role (~20 hours/week) for the first month with a direct path to full-time employment as you take over full in-house billing and credentialing operations.
