Author name: Marcus Bennett
Marcus Bennett is a Certified Professional Coder (CPC, AAPC) and Certified Revenue Cycle Representative (CRCR, HFMA) with more than 12 years of experience in medical billing denials, appeals, and accounts receivable management. He has worked with physician groups, specialty clinics, and hospital-affiliated practices across New York, Texas, and Florida, recovering millions of dollars in denied and underpaid claims over the course of his career.
Marcus began his career in the A/R follow-up department of a large multispecialty group in New York City, where he developed a systematic approach to denial analysis categorizing denials by root cause, tracking denial trends by payer, and building internal workflows that reduced the group's overall denial rate from over 12% to under 5% within two years. He later transitioned into a consulting role, helping smaller practices build denial-management processes from scratch.
He has extensive hands-on experience with every major claim adjustment reason code (CARC) and remittance advice remark code (RARC), and he understands exactly how to read an EOB to identify whether a denial is worth appealing, how to build a compelling appeal letter, and when to escalate to a payer's dispute process. Marcus writes to give billers and practice managers the exact information they need to work a denial file — no filler, just resolution steps.
Specialties: Claim denial prevention and resolution, CARC and RARC code interpretation (CO-45, CO-97, PR-204, CO-16, CO-29 and 50+ others), appeal letter writing, timely filing disputes, AR days reduction, denial trend analysis, underpayment identification, prior authorization denials, payer-specific denial patterns.
