The Code is organized into the following six major divisions:

1. (1) Titles. Each Title identifies an administrative agency, except for Title 1 which includes executive orders.
2. (2) Chapters. Each Chapter identifies a major area of regulatory control within an agency's authority. Each Chapter identifies a group of Sections which are:
3. (A) related to the same major agency program or legally-designated regulatory power;
4. (B) dependent on a common set of definitions; or
5. (C) independent of another Chapter in meaning or effect.
6. (3) Subchapters. Each Subchapter identifies a group of Sections related to the same general subject within a Chapter. The use of Subchapters is optional.
7. (4) Parts. Each Part identifies a group of Sections related to the same subject within a Subchapter. The use of Parts is optional.
8. (5) Sections. Each Section identifies a specific agency statement within a Chapter, Subchapter, or Part. Each Section is considered to be a single "rule." [See Part 5 of this Subchapter (relating to Code numbering, headings, and taglines)]
9. (6) Appendices. Each Appendix identifies a graphic in compressed image format (JPG), as defined in 655:10-1-2, which the agency considers to be regulatory text (i.e., text requiring promulgation). Each Appendix is considered to be a single "rule."
