Coding a new patient’s 2 visits in 1 day
<huc>Q</huc> One of our doctors saw a new patient in labor and delivery, and then she was seen in our office for a more extensive exam and ultrasound on the same day, but by a different doctor. Normally I would bill both with a -59 modifier (Distinct procedural service) assigned to an evaluation-and-management (E/M) code, but I was recently told that the -59 modifier should not be assigned to an E/M code. How should I bill for these 2 separate encounters?
<huc>A</huc> You are correct. While the modifier -59 may be assigned when a distinct and separate service was provided on the same date of service, such as when there is a separate patient encounter, the services referred to in the CPT guidelines are medicine and procedural services, not E/M services. An article in the American Medical Association’s CPT Assistant (January 1999) clarified that the modifier -59 may not be appended to E/M services.
If the patient is seen for the same reason and the physicians are considered the same under the payer’s rules, bill only 1 E/M service for that day, but take into account all of the care the patient received during both encounters to select the right E/M service level. The ultrasound, of course, will be billed as well.
If the payer allows more than 1 encounter on the same day, the second encounter in the office must be reported as an established patient service, since a new patient service applies to the first encounter that day.
There are no appropriate modifiers that can be added to the second E/M service.
