Executive Team
Marnie Cabezas
Chief Executive Officer
In the early 90s, our CEO, Marnie Cabezas, began her career as a midwife. While helping new moms bring babies into the world, she noticed that she and her colleagues were having trouble getting reimbursed for their work, so, in 1998, she purchased Midwife’s Billing Service, Inc. Armed with a powerful will and a desire to help midwives receive fair compensation for their invaluable services, Marnie conquered the ins and out of billing, coding, and contracting while riding the rollercoaster of ever-changing rules and technologies—from the early days of HIPAA, working with MS-DOS and dot matrix printers, up through today’s powerful clearinghouses, portals, and EHRs.
Her business has been growing steadily through all the industry changes, and, in 2016, Marnie decided that to better showcase that the company was open to all independent medical practitioners, changing the name to Innovation Billing Service, Inc. was a natural result of the continued growth and services offered.
It is said that being a medical practitioner—someone who cares for others—is a calling. The skills, time, and energy required to do the job well deserve both respect and the compensation to go along with it, which is why Marnie feels so strongly about ensuring reimbursement for all who are called upon to care for others.
