CPT 2018 Professional Edition is the definitive AMA-authored resource to help health care professionals correctly report and bill medical procedures and services. Providers want accurate reimbursement. Payers want efficient claims processing. Since the CPT code set is a dynamic, ever changing standard, an outdated codebook does not suffice. Correct reporting and billing of medical procedures and services begins with CPT 2018 Professional Edition. Only the AMA, with the help of physicians and other experts in the health care community, creates and maintains the CPT code set. No other publisher can claim that. No other codebook can provide the official guidelines to code medical services and procedures properly.
