Ask the expert: What is an A-Tag?

Tags are a system used by CMS to define a regulation number. Instead of denoting a regulation by using its full reference, the regulation is referred to as A-Tag 0700, for example. Specific tags are assigned to different healthcare facility types. For instance, hospitals use Appendix A or A-Tags, while ambulatory surgery centers use Appendix L or Q-Tags, and critical access hospitals follow Appendix W or C-Tags.
