EKG interpretation with ER visit billing question

A patient was seen in the ER, and an ER visit 99284 was billed. An EKG was done that was ordered by the ER doctor, who reviewed it but did not do a formal interpretation. A cardiologist did an interpretation of the same tracing later on the same date. Can the cardiologist's interpretation be billed as 93010? I know if that if the ER doc had done an interpretation it would be included in the ER visit, but if a provider of a different specialty interprets it, can this be billed separately...
