Read the beginning of the E/M services section in the CPT book. The header is History and/or Examination. If you have the hard copy 2025 CPT Professional Edition, it's on page 7. "E/M codes that have levels of services include a medically appropriate history and/or physical examination,
when performed." Continue reading the paragraph and you will see it is not a requirement. The final sentence is, "The extent of the history and physical examination is not an element in selection of the level of these E/M service codes." However, while not technically a requirement to bill an E/M it would still be expected to see
something to establish medical necessity, show continuity of care, and from a med-legal standpoint.
That being said, I think it depends on the setting, type of service, patient, and problem, etc. There could be some cases where you would not necessarily see these documented. What specialty are you reviewing? You definitely need a chief complaint/reason for visit.
As for the MRI review, it depends. Who ordered the MRI and performed the interpretation? If the provider is trying to take credit for an MRI they had already ordered and your practice billed for it in house, they can't get double credit by billing an E/M again later for reviewing it. If they are reviewing an outside/external MRI they did not order or get credit for prior, they can take credit for it later. Further, it depends on if they did an independent interpretation or just reviewed it. Second opinion scenarios have this.
For the time based, it again, depends on the documentation. There could be a case where they might not have an exam. It could be a complicated patient where they spent 60 minutes talking about options but no exam was needed.
This is all really dependent on the specific documentation of the encounter. However, if I was looking at a larger sample of a provider's notes over time, none of the notes ever had any history or exam - red flag. If every single visit was billed based on time with the exact same time statement, that would be cause for concern too.
CMS and others would be looking for: "Thus, when billing an E&M service, document the patient's condition, what medically necessary service(s) were provided, and the reasoning for those services, based on the patient's needs at that time."
If the provider is billing a 5 yet the reviewer can't tell what the patient was there for and see the thought process documented, it's not going to fly.

“E/M Codes that have levels of services include a medically appropriate history and/or physical examination when performed. The nature and extent of the history and/or physical examination is determined by the treating physician or other qualified healthcare professional reporting the service. The care team may collect information and the patient or caregiver may supply information directly (e.g., by electronic health record portal or questionnaire) that is reviewed by the reporting physician or other qualified health care professional. The extent of history and physical examination is not an element in the selection of the E/M services.” CPT 2025 Professional Edition, AMA P. 7
There is a plethora of info about this when doing a search. Most of the MACs address this in the FAQ and E/M sections. The CMS EM services guide is currently under construction but would be found here:
