I personally would likely bundle the care provided into 1 E/M. If the patient didn't have the telehealth in the morning, he would not have had the in-person office visit in the afternoon.
You indicate "call" in your post. If by call, you mean this was an audio only telephone call, then it's definitely not separately billable.
99441-99443 specify do not originate from a related E/M service within the previous seven days and do not lead to an E/M service or procedure within the next 24 hours or soonest available appointment. In that case, the telephone call, although started for a different issue, did lead to an E/M service within 24 hours or soonest available. To me, this is clearly 1 E/M service with all work being counted.
If by "call" you mean a video interaction billed with E/M, it's more of a gray area.
CMS specifies 2 E/M services by same physician (or physician group of same specialty), same day, is not separately billable unless it is for 2 unrelated problems. I would have to check references, but I believe CMS specifies modifier -25 in that situation.
Many commercial carriers will set their own rules about this and may not allow 2 E/M visits, even if for different reasons.
Since the provider & patient discussed his leg in the morning (some HPI elements are there), and the provider made a very brief assessment, I personally would not feel comfortable billing 2 separate E/M, and would bundle all work into 1 E/M.
Hope that helps!
