Ms. Phish: "Hi, this is Cindy over at Dr. Weneverheardofhim's office, and we want to refer a patient to you."
Mary: "Okay, what's their insurance?"
Ms. Phish: "Hang on, to refer them we need Dr. Grumpy's address and Social Security number."
Mary: "Uh, you don't need his SS number to refer a patient. I can give his medical ID, which is what all plans require."
Ms. Phish: "No, this insurance requires the doctor's SS number."
Mary: "What insurance is that?"
Ms. Phish: "National Illness."
Mary: "We work with National Illness, and they don't..."
Ms. Phish: "LOOK! Just give me the doctor's SS number, or we will never send you another patient again!"
