appendix F | is a summary of CPT codes that are exempt from modifier 63 |
appendix G | has codes that include conscious/moderate sedation |
appendix H | is an alphabetic index of performance measures by clinical conditions or type but was removed from CPT |
appendix I | has genetic testing code modifiers used for reporting with lab procedures related to genetic testing |
appendix J | includes a list of sensory, motor, and mixed nerves that are useful for nerve conduction studies |
appendix K | lists procedures included in the CPT codebook that are not yet approved by the FDA |
appendix L | is a reference of the vascular families, including which are considered first-, second-, and third-order vessels |
appendix M | shows a table of deleted CPT codes and crosswalks to current codes |
