If a code should apply to only Anterior or Posterior regions, it can be added to the Anterior Only or Posterior Only subcategory in the Charting Code Map. Adding codes to the Anterior Only or Posterior Only subcategories should be handled with care.
For example, if a Posterior Only code is necessary, the code can be added just as any other code to the Posterior Only subcategory folder. However, this will activate the Posterior Only subcategory so that a code must remain in the Posterior Only subcategory in order for the category to exist.
Should the only code within the subcategory be deleted, the subcategory itself will be deleted.
Prior to deleting codes, see the Deleting Codes section.
