Pulmonology Coding Alert

Can new patients get treatment incident-to the physician?

You might think you've got nonphysician practitioner (NPP) coding down pat, but the regulations change so frequently that you should test your skills from time to time. Take a few minutes to challenge yourself with our NPP coding quiz and make sure you're on the right track. Established Patient, New Problem: Is it Incident-to? Question 1: Your nurse practitioner (NP) examines an established patient with a COPD exacerbation.  During the evaluation for the COPD exacerbation, the patient complains of pain and redness around a recent cut on his arm.  The NP discovers a skin infection on the left arm.   The pulmonologist is in the suite but is unable to come into the examining room to evaluate the new problem, so the NP debrides the wound and gives the patient an antibiotic prescription. Can you bill the visit incident-to, or should you bill it under the NP's provider identification number (PIN)?

Answer 1: "This visit must be billed under the NP's number and is not an incident-to visit," says Ron L. Nelson, PA-C, president of Health Services Associates in Fremont, Mich., and past president of the American Academy of Physician Assistants. "This is clear-cut and based upon the regulations would require the billing to be under the NP's number," he says.

Here's why: Even though the NP saw an established patient, the visit doesn't qualify as incident-to because a care plan has not been established for the new problem. If the NP addresses the skin infection (a new problem) without the physician's input, then the NP should bill the visit using his own PIN.

That's because the incident-to guidelines require the physician to initiate the care plan for any new patients, or any new problems that the patient has.

Some insurers have interpreted this to mean that the physician must provide the visit associated with new patients or new problems.  Subsequently, the NPs will implement the physician-established plan of care (i.e. "incident-to" the physician's service).  Otherwise, your NP can still bill the visit, but he must do so using his own identification number. Can the PA Request/Perform Consults? Question 2: A physician's assistant (PA) from a local primary care physician asks your pulmonologist to evaluate a patient whom he suspects suffers from bronchitis. Can you bill a consult when the request comes from a PA, and not a physician?

Answer 2: Yes. "According to Medicare guidelines, PAs can request consults, and can perform consults under certain circumstances," says Stephen Levinson, MD, author of the AMA's Practical E/M: Documentation and Coding Solutions for Quality Patient Care.
