Sign of the changing times: CPT 1999

Although CPT 1999 contains fewer changes than in past years, coders should take some time to learn them by: familiarizing themselves with the new symbols + and [symbol: see text] reviewing Appendix A for a complete list of modifiers as well as modifiers used in the ambulatory surgery center hospital outpatient setting; reviewing Appendix E for a complete list of add-on codes; reviewing Appendix F for a list of modifier-51-exempt codes; consulting the excludes note found above code 69,990 to identify procedures exempt from the use of the new operating microscope code; examining the specific codes used to identify bronchoscopic procedures; reviewing the parenthetical notes found after code 15,001, directing the coder to also assign the appropriate code for lesion excision; reviewing the changes associated with the coding of destruction of lesions understanding the changes in immunization code assignment; consulting payers for specific reimbursement guidelines.
