Portable Equipment Financial Considerations
a. What are some financial considerations?

Several important financial questions need to be answered when considering a portable dental program or practice:

Many portable dental programs have been funded by grants from federal agencies such as HRSA's Maternal and Child Health Bureau or CDC's Division of Oral Health, state or local health departments, community foundations or other local resources.

If you plan to bill Medicaid or other insurance programs, remember that it takes a while to apply for and receive a provider number if you don't already have one. Some hygienists who work in states that allow direct reimbursement to dental hygienists have experienced problems getting provider numbers, or having private insurance companies send the reimbursement check to the beneficiary instead. Sometimes this can be difficult to collect from the patient or family. 
A number of financial benefits are available to practitioners who establish a portable/mobile practice for underserved populations.

"Consider the tax benefits: write-offs in a portable practice if based out of the home include a percent of phone, utilities, rent or mortgage, furniture, and the like. For the vehicle used to transport the practice, a percent of mileage, gas, maintenance, repairs, licenses, and insurance can be written off. … the set-up costs are low compared with a traditional practice … and overhead is minimal. Free use of facilities, no expenses for time off, and other advantages add up to low operating costs… no more unproductive time waiting for a patient to come to the office."
