About this Course

The Centers for Medicare & Medicaid Services (CMS) Medicare Learning Network® created this Diagnosis Coding: Using the ICD-10-CM training course.

This self-paced course provides a practical understanding of ICD-10-CM structure, coding conventions, and official guidelines. It is designed for professionals who do not code day-to-day, yet these roles still need a solid working knowledge of ICD-10-CM because coding accuracy directly affects their work. This includes compliance officers, revenue cycle professionals, Medicare coverage analysts, auditors, healthcare IT professionals, software developers, C-suite executives, healthcare fraud attorneys, healthcare transaction attorneys, and healthcare consultants.

By focusing on accurate code selection and real-world application, the training supports clean claims, proper reimbursement, reliable financial forecasting, stronger compliance, and reduced False Claims Act risks.
