Coding Resources and Information

Coding Basics - The First Step to Ensure Proper Coding

The first step to ensure proper coding involves selecting the most reliable and reputable coding products from the hundreds of coding resources available, from books to software to consultants’ products. This can be easier than it sounds. The first step is determining which resources are essential and which should be used as supplements.

Coding Essentials
Essential items for correct coding are CPT and ICD-9-CM manuals from the current year. Each year, new CPT codes are added and existing codes revised or deleted, therefore, it is very important to use only current coding manuals. Use of outdated manuals can lead to reimbursement inefficiencies, lost revenue or compliance problems. New CPT codes and updates become effective January 1; ICD-9-CM code additions and revisions become effective October 1.

You can purchase CPT and ICD manuals from the American Medical Association (AMA) at or by phone at (800) 621-8335. The same manuals can also be purchased from other vendors such as Ingenix. The National Center for Health Statistics (NCHS) and the Centers for Medicare and Medicaid Services are the U.S. governmental agencies responsible for overseeing all changes and modifications to the ICD-9-CM.

Coding Resources
A number of resources are available to help physicians and others code correctly, such as the following:

Online Coding Resources - ASGE offers a variety of convenient and robust online options to immediately help you as well as your entire GI team prepare for a smooth transition to ICD-10.
