Mark Lester Del Rosario

With over 6 years of experience in U.S. healthcare operations, I specialize in medical billing, charge auditing, insurance verification, and patient coordination across both clinical and administrative settings. I’ve supported end to end revenue cycle processes for medical, behavioral health, and DME services—ensuring accurate coding, timely reimbursements, and compliance with payer guidelines.

Throughout my career, I’ve developed deep familiarity with Revenue Cycle Management RCM systems such as Epic, 3M, AdvancedMD, DME Scripts, Allscripts, Go Scripts, and Brightree. I also use payer portals like Availity, TevixMD for eligibility checks, claim submissions, and appeals. My hands on experience with both frontend and backend billing processes includes coordinating directly with insurance companies to resolve claim denials, secure prior authorizations, and ensure complete reimbursement across various lines of business, including Medical , Workers’ Compensation, and Auto Insurance.
