I am in a discussion with my Compliance Department on whether, with an infant patient, can a parent be considered an independent historian when obtaining the HPI and therefore be given 1 data point when scoring the MDM under 2021 guidelines? They say no, but I have not come across anything that states specifically that it cannot. The AMA guidelines give the parent as an example of an IH and goes on to state "due to developmental stage" of the patient. What are others doing regarding this?
