Hi, this is what I found in the Medicare Claims Processing Manual, section 30.6.11 F.,
http://www.cms.hhs.gov/manuals/downloads/clm104c12.pdf :
F. Emergency Department Physician Requests Another Physician to See the
Patient in Emergency Department or Office/Outpatient Setting
If the emergency department physician requests that another physician evaluate a given
patient, the other physician should bill a consultation if the criteria for consultation are
met. If the criteria for a consultation are not met and the patient is discharged from the
Emergency Department or admitted to the hospital by another physician, the physician
contacted by the Emergency Department physician should bill an emergency department
visit. If the consulted physician admits the patient to the hospital and the criteria for a
consultation are not met, he/she should bill an initial hospital care code.
Hope this helps,
Donna
