2025 Telehealth CPT Codes & Modifiers: The Ultimate Guide for Accurate Medical Billing

Introduction

Telehealth has transformed the healthcare delivery model in recent years, allowing providers to extend quality care to patients remotely. As virtual care continues to grow in popularity, staying updated with the latest CPT codes and modifiers is essential for accurate reimbursement and compliance.
