Coding with Modifiers A Guide to Correct CPT and HCPCS Level II Modifier Usage 4th Edition by Deborah J Grider ISBN 160359616X 978-1603596169

Grider, a certified professional coder, shows medical assistants, medical insurance specialists, new medical office personnel, physicians, independent billing personnel, and other health care providers how and when to use modifiers with Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS) codes to indicate that a service or procedure was modified in some way. She explains the purpose of modifiers, the relationship to the reimbursement process, logic trees related to usage, and how Medicare carriers and intermediaries vary on the use and acceptance of modifiers. Chapters are organized by modifier and illustrate proper and improper use through clinical examples. They include coding tips, American Medical Association and other guidelines, and exercises. Both code and subject indexes are provided.
