Private Allergy & Immunology Practice

Location: Hinsdale/Clarendon Hills, IL area
Schedule: Monday–Thursday | 27–40 hours per week
Position: Part-Time or Full-Time, In-Person
Compensation: Competitive, based on experience

About the Position

We are an established, growing, privately owned Allergy & Immunology practice seeking a highly experienced, dependable, and proactive Medical Office Manager to oversee daily operations.

Our goal is to find an exceptional manager who can independently run the practice, lead our team, oversee billing and financial operations, and allow our physicians to focus on patient care rather than day-to-day administrative issues.

The ideal candidate has extensive medical office management and billing experience, strong leadership abilities, excellent judgment, and a demonstrated history of successfully managing a medical practice with minimal supervision.

This is a hands-on leadership position requiring initiative, accountability, and the ability to identify and resolve problems independently.

Key Responsibilities

Practice Management & Leadership

• Independently oversee daily administrative and operational functions.
• Supervise, train, schedule, and manage administrative staff.
• Oversee hiring, onboarding, employee performance, and accountability.
• Manage physician schedules and patient flow to maximize efficiency and growth.
• Handle patient complaints and operational issues professionally and independently.
• Develop and improve office workflows, policies, and procedures.
• Maintain effective communication between physicians, clinical staff, and administrative personnel.

Medical Billing & Revenue Cycle Management

• Oversee medical billing operations, insurance claims, and patient collections.
• Understand CPT codes, insurance reimbursement, deductibles, copays, and patient financial responsibility.
• Review and resolve claim denials, rejections, and payment discrepancies.
• Monitor accounts receivable, outstanding balances, and collection processes.
• Oversee insurance eligibility verification and benefits interpretation.
• Identify billing inefficiencies, reimbursement issues, and opportunities to improve collections.
• Coordinate with billing staff or external billing services and ensure timely follow-through.
• Resolve complex patient billing disputes and insurance-related questions.

Required Qualifications

• Prior medical office management experience, preferably 3–5+ years.
• Hands-on experience with medical billing, insurance claims, denials, accounts receivable, and revenue cycle management is required.
• Proven experience supervising employees and independently managing office operations.
• Strong understanding of medical insurance, patient financial responsibility, and reimbursement processes.
• Excellent leadership, organizational, communication, and problem-solving skills.
• Ability to handle difficult situations confidently and professionally.
• Self-motivated, highly dependable, proactive, and detail-oriented.
• Proficiency with electronic medical records and practice management software.
• Excellent professional references from previous supervisors, employers, or physicians are required.

Preferred: Experience with Athenahealth EMR, specialty medical practices, and allergy/immunology billing.

What We Offer

• Flexible schedule of 27–40 hours per week, Monday–Friday.
• Competitive compensation based on experience.
• Established, privately owned medical practice.
• Significant autonomy and decision-making responsibility.
• Opportunity to make a meaningful impact on practice efficiency and growth.
• Long-term position in a collaborative, patient-focused environment.

Our Ideal Candidate

We are seeking a true practice leader who is equally comfortable managing people, overseeing billing, and improving daily operations.

The right candidate will take ownership of the practice's administrative and financial workflows, anticipate and solve problems, hold staff accountable, and ensure the office runs efficiently without constant physician oversight.

This is not an entry-level administrative position. Demonstrated medical office management experience, strong medical billing knowledge, and excellent professional references are essential.

To Apply

Please submit your resume and a brief description of your previous medical office management and billing responsibilities.

Qualified candidates will be asked to provide professional references during the hiring process.
