Years of experience

With over 30 years of experience in medical billing, coding, insurance follow-up, and revenue cycle management, I have worked across multiple healthcare specialties, including Hospice Billing, Internal Medicine, Family Practice, Physical Therapy, Occupational Therapy, Orthopedics, Infertility, and Ambulatory Surgery Centers.

My expertise includes medical billing, coding, accounts receivable, insurance follow-up, payment posting, collections, denial management, appeals, and reimbursement recovery. I have extensive experience working with Medicare, Medi-Cal, commercial insurance, HMOs, PPOs, Workers' Compensation, and Personal Injury claims, along with ICD-10-CM, CPT, HCPCS, EOB analysis, UB-04, and CMS-1500 claim forms.

Throughout my career, I have managed AR portfolios ranging from $50,000 to over $1 million, consistently reducing aging accounts, resolving denials, recovering underpayments, and improving cash flow.

I am proficient in Medisoft, Hospice MD, Epic, Prime Clinical, Topaz, and Practice Mate (Office Ally). Working from a fully equipped home office, I am organized, detail-oriented, and able to quickly adapt to new systems and workflows through both long-term and contract assignments.

I welcome the opportunity to discuss how my experience can contribute to your organization's success.
