About How To Bill Cpt 99203 In Medical Billing Correctly In 2025

In 2025, CPT 99203 in medical billing continues to be one of the most commonly used new patient visit codes. This code is used when a provider evaluates a new patient with moderate complexity medical decision-making and spends approximately 30–44 minutes face-to-face. Understanding how to bill CPT 99203 in medical billing accurately can mean the difference between timely reimbursement and frustrating claim denials. For many healthcare providers, this code is a cornerstone of evaluation and management (E/M) billing because it reflects moderate complexity not too simple like CPT 99202, and not as involved as CPT 99204. As someone who’s worked closely with multiple physician practices, I’ve seen firsthand how small documentation errors can cause reimbursement delays. Once, a family medicine clinic I consulted for lost nearly $3,000 a month in denials simply because their documentation didn’t match CPT 99203 requirements. With the right guidance and billing process, they fixed it within weeks and their clean claim rate improved dramatically.
