E.R.I. has over 20 years of medical billing experience. In that time E.R.I. has been contracted by Insurance Companies who refer there own medical equipment, Manufacturer's Reps who purchase and distribute their own medical equipment ( both through us and elsewhere), Physical Therapists who dispense their own medical equipment, etc. The one thing they all have in common is that they realize the difficulty and expense of billing, tracking and servicing DME. E.R.I. can service any one or all of these frustrating segments of DME disbursement.
