Mayo Clinic physicians are committed to collaborating with referring physicians. Telephone consultations and referrals may be arranged by contacting the Referring Physician Service.

To refer a patient:


Contact Referring Physician Services at 800-533-1564 (toll-free) 24 hours a day, seven days a week. Mayo Clinic hematologists are happy to discuss possible referrals with physicians and their staffs outside of Mayo Clinic.

Hematologists generally can see most patients within two weeks after the appointment request, and often can see patients within a week or less after the appointment request. Patients with urgent issues can usually be seen within 24 hours after their requests. In emergencies, patients are directly transferred to inpatient hospital care.
