Neurosurgery Coding Alert

Question: A provider insurance representative recommended at an in-house seminar that if our surgeon sees a patient in the hospital, we can still bill as a "new patient" if we later see him in the office. But, when one of our surgeons treats a patient in the hospital whom he later sees in our private practice, I've been considering that patient to be "established." Who is correct?

Answer: You are correct.

CPT defines a new patient as "one who has not received any professional services from the physician or another physician of the same specialty who belongs to the same group practice within the past three years."

Show the insurance representative CPT's new and established patient definition nder the heading "Definitions of Commonly Used Terms" in Evaluation and Management Services Guidelines. The representative may be unfamiliar with in-office coding that follows this rule.

Of course, payers often make their own guidelines that deviate from CPT. If that's the case in this (or any) situation, get the payer's recommendations in writing.

A patient's status doesn't affect hospital care coding. For instance, you report initial hospital care with 99221-99223 (Initial hospital care, per day, for the evaluation and management of a patient ...) and subsequent hospital care with 99231-99233 (Subsequent hospital care, per day, for the evaluation and management of a patient ...), regardless of whether the patient is new or established.

But, if one of your surgeons treats a patient in the hospital and later (within three years) treats the patient in the office, you must code the encounter as an established patient E/M service, such as 99212-99215 (Office visit for the evaluation and management of an established patient ...).
