This code is used in Radiation Oncology for E/M services provided during ongoing radiation treatments. CMS instructions on the use of the code are clear for how frequently it can be used (billable 1 time for every 5 fractions of radiation treatment). I've also heard (most recently in AAPC's webinar May 2024) that there is a global period of 90 days which is maybe attached to the 77427. I cannot find documentation to support this rule and wondered if there is anyone out there who has seen this in an LCD or somewhere else?
