Question: Many times we need to know the global days of a procedure to help us decide coding issues such as what modifier to use or whether to code a separate E/M procedure. How can we quickly determine CMS's global period for any CPT® code? Kansas Subscriber Answer: If you subscribe to an online coding tool such as Codify, you can see the global period and lots of other payment and coverage information about each code when you look it up.
But you can also always find the global days on the Medicare Physician Fee Schedule website at (https://www.cms.gov/apps/physician-fee-schedule/search/search-criteria.aspx). To find the global period, follow these steps once you're at the website: Once you get to the global column, you will see one of the following seven codes.

The following table defines these codes: Remember: You should always verify with third-party payers that they are following the Medicare guidelines before using the information for your claims.
