How to Schedule a Patient

To schedule a clinic visit, refer a patient, or speak with one of our physicians, please contact us at:

  • How to refer a patient to Jefferson? Call 1 800-JEFFNOW and ask the operator to schedule a new patient visit with one of the physicians listed above for an evaluation of interstitial lung disease.
  • What to expect from your referral? Upon completion of our evaluation, our physicians will provide a written report to the referring physician outlining the diagnosis and suggested treatment plan. Subsequent management will be arranged between the physicians and patient.
  • May I retain management of my patient after referral to Jefferson? Yes. We encourage that patients continue to see their referring physician regularly and obtain testing locally, though we also enjoy seeing the patients intermittently in order to maintain continuity should the patient’s condition change over time.
