How to use the Book
Select the procedure code from the alphabets index given at the end of the CPT book. There are four primary classes of main entries,
1. Procedure / Service – For Eg: Endoscopy, splint
2. Organ / Anatomic site – For Eg: Colon, Tibia
3. Condition - For Eg: Abscess, Tetralogy of Fallot
4. Abbreviation – For Eg: EEG
Refer the respective CPT description along with the parenthetical notes given below the CPT code, and related CPT guidelines (Specific guidelines are given at the beginning of each section).
If there is no CPT code available in the CPT book that exactly describes the service provided, don’t code which is near approximates instead we can report appropriate unlisted procedure codes.
CPT codes are arranged like Stand-alone code and one or more indented code.
Eg: CPT 73120 (Radiologic examination of hand; 2 views)
CPT 73130 (Minimum of three views)
For CPT 73130 Should read this as a Radiologic examination of hand; minimum of three views.
