Referring a Patient

To refer a patient for medical dermatology, please fax a referral to the preferred site for your patient. We request that referrals be made to "Johns Hopkins Dermatology" (regardless of subspecialty) to ensure that your patient will be seen at the earliest opportunity and by the subspecialist for the condition.  After the visit is completed, we will fax a copy of the visit notes to you to ensure continuity of care for your patient.
