Answer: The only kind of consult Dr. B. can bill is a confirmatory consultation (99271-99275) because the patient has decided to go to Dr. B. on his own for treatment. Instead of going to Dr. A so Dr. A can give his or her opinion to the primary-care physician, the patient is going to Dr. B on the patient's own recommendation, not on the referral of the primary-care physician.
