The guidelines for data state "If a test/study is independently interpreted in order to manage the patient as part of the E/M service, but is not separately reported, it is part of medical decision making". In other words, they are saying that if the provider is reporting the interpretation separately then it would not count toward the MDM. It does not say that if the provider's office or facility is billing the technical component that it would not count toward the data in the MDM.
So, as I understand it, if the test has a professional component that the provider is reporting separately, such as the interpretation of an EKG being billing with 93010, then that provider cannot count the EKG in the MDM. But interpretation of clinical lab tests is never reported separately (there is no CPT code for a provider to bill for interpreting a UA). It would always be appropriate to count the ordering or interpretation of labs as part of MDM, regardless of whether the lab is billed by the office or billed by an outside lab.
