I’m Maria Carreno, CPC, CRCR, a healthcare Revenue Cycle Management professional with 30 years of experience in medical coding, coding denials, appeals, provider education, and revenue cycle operations.

I created RCM & Coding Made Simple to turn real-world experience into practical, easy-to-use resources for medical coders and RCM professionals.

My goal is simple: less guessing, smarter denial review, and better results.
