Primary Care Coding Alert

You can't report incident-to unless FP authored care plan

When one of your nonphysician practitioners (NPPs) provides services or treatment to a Medicare patient, you should check the encounter notes to see if you can code the service incident-to the physician.

Why? More money for the same service. When you report services incident-to your family practitioner (FP), you can bill under the physician's Medicare unique physician identification number (UPIN) and garner full pay for services.

If you do not bill an NPP visit incident-to the physician, the NPP must bill under his own UPIN, which Medicare reimburses at 85 percent of the rate otherwise paid to physicians. (Note: The term UPIN will soon be replaced by the national provider identifier, NPI.)

Of course, Medicare has strict guidelines regarding what constitutes an incident-to service, so if you-re concerned with the bottom line, you should know the ins and outs of incident-to coding.  Find Out if Patient Had a Plan of Care To bill incident-to services, the NPP must be following an established plan of care for the patient and the physician supervision requirements, says Anna Rosario, CPC, coding and compliance officer for Affiliated Practice Group in Brockton, Mass. If the NPP sees the patient for a new problem, you cannot bill incident-to.

Example 1: The FP sees a new Medicare patient with type II diabetes with ketoacidosis and benign hypertension, and schedules the patient for a follow-up visit. Two weeks later, the NPP provides a level-two E/M service for the patient to check on his diabetes and hypertension.

In this instance, the NPP followed the doctor's care plan, so you can report an incident-to service, says Mary Falbo, MBA, CPC, president of Millennium Healthcare Consulting Inc. in Lansdale, Pa.

On the claim, you should report 99212 (Office or other outpatient visit for the evaluation and management of an established patient, which requires at least two of these three key components: a problem-focused history; a problem-focused examination; and straightforward medical decision-making) for the E/M under the physician's UPIN.

Don't forget to attach ICD-9 codes 250.10 (Diabetes with ketoacidosis; type II or unspecified type, not stated as uncontrolled) and 401.1 (Essential hypertension; benign) to 99212 to prove medical necessity for the encounter.

Example 2: A new patient comes to the office complaining of stomach pains. The NPP treats the patient and establishes a care plan for treating gastroesophageal reflux disease (GERD).

In this example, the patient received treatment for a new problem, meaning the NPP was not following an FP-established care plan, Falbo says. In this instance, you should code for the NPP's service under the NPP's UPIN number.

In a nutshell: Anytime the NPP sees a patient independently for a new problem, you should code for the service with her [...]
