ICD-10-CM coding can be challenging for coders in the outpatient setting. It is important to remember that the Official ICD-10-CM Guidelines for Coding and Reporting provide a road map to ensure accurate diagnosis coding.
Four organizations, otherwise known as the Cooperating Parties, are responsible for maintaining the ICD-10-CM code set: the American Hospital Association, American Health Information Management Association, CMS, and the National Center for Health Statistics. Coders must understand that conventions, general guidance, and chapter-specific guidelines should also be utilized when coding for outpatient services and office visits.
