ABC Code Structure

 
 
ABC codes consist of five-character, alphabetic strings that identify services, remedies, and/or supplies. Codes are followed by two-character code modifiers which identify the practitioner type who delivered the care.

Example:

The following description illustrates the coding hierarchy of ABC code NAAGN - Pain management and/or control initial 60 minutes, Managing and/or controlling a patient's pain levels. For additional time, use NAAGO. Service is billed in 60-minute increments.



The hierarchal meaning of the first three letters of each ABC code is shown in the following code tree:

The code tree groups similar services, remedies, and/or supplies into meaningful sections, subsections and headings. For example, Labor and delivery is located in Section C (Practice specialties), Subsection E (Reproduc­tive and/or childbirth services), Heading C (Labor and delivery). Applicable codes therefore would be found in the “CEC”
