Neurology & Pain Management Coding Alert

Get 15 percent more for same service in certain situations.

Practices often use incident-to billing in order to in order to maximize resources — and payment. This billing convention allows nonphysician practitioners (NPPs) to provide evaluation and management (E/M) services to patients without the physician’s accompaniment in certain situations.

When allowed, reporting incident-to means that you can bill your NPP’s services under the National Provider Identifier (NPI) of the physician; this will garner you 100 percent of the E/M payment, as opposed to the 85 percent reimbursement rate that accompanies the NPP’s NPI.

When not allowed, reporting incident-to means courting payers’ and regulators’ wrath. There are some very specific rules for reporting incident-to, and failure to follow even one of them will raise the eyebrows of anyone looking for upcoders. Check out our advice on reporting incident-to correctly every time.

Remember, Medicare Made Incident-to

First things first: You need to know how to proceed with potential incident-to claims — because not all payers will recognize the coding convention, says Mary I. Falbo, MBA, CPC, CEO of Millennium Healthcare in Lansdale, Pennsylvania.

“It is important to check with each of your carriers before billing services incident-to,” she warns. “Keep in mind that incident-to guidelines were developed by Medicare, and other insurance carriers do not necessarily follow Medicare’s lead. It is important to check with the third-party payers to ascertain if they follow Medicare’s incident to guidelines or State Law or obtain clear guidelines as to their requirements.”

The Centers for Medicare & Medicaid Services (CMS) defines incident-to services as “services or supplies furnished as an integral, although incidental, part of the physician’s personal professional services in the course of diagnosis or treatment of an injury or illness.”

CMS reports that in order to be covered as incident-to the physician, the service must:

• “Be an integral, although incidental, part of the physician’s professional service;
• “Of a type that are commonly furnished in physician’s offices or clinics; and
• “Furnished by the physician or by auxiliary personnel under the physician’s direct supervision.”

If your encounter doesn’t meet all these criteria, don’t even think about coding incident-to.

Use Incident-to for These Codes

Remember that E/M codes are what incident-to guidelines were designed for. There’s no incident-to billing of a procedure code.

Also, as CMS insists that incident-to services must be “commonly furnished in physician’s offices,” you won’t be able to report hospital E/M codes.

Lastly, the patient must be established in order to report a service incident-to.

Takeaway: You’ll be reporting your incident-to claims with office/outpatient codes 99211 (Office or other outpatient visit for the evaluation and management of an established patient that may not require the presence of a physician or other qualified health care professional.) through 99215 (Office or other outpatient visit for the evaluation and management of an established patient, which requires a medically appropriate history and/or examination and high level of medical decision making. When using time for code selection, 40-54 minutes of total time is spent on the date of the encounter.).

Locate Care Plan Before Coding

An NPP can only bill incident-to a physician if they are following an established plan of care, Falbo confirms. And CMS seems to be cracking down on this criterion, according to recent guidance from the CMS Medical Review (MR) Department.

From February 2022 CMS MR Department guidance:

“An initial history and physical performed by a non-physician practitioner, although the physician is documented as being present or in the office suite and immediately available, is not covered under the ‘incident to’ guidelines. The physician must perform the initial service. This includes the history and physical, examination portion of the service, and the treatment plan. It is expected that the physician will perform the initial visit on each new patient to establish the physician-patient relationship.

“Our MR will deny or down code claims for initial office visits billed as ‘incident to’ when a non-physician practitioner performs the initial history and physical,” CMS cautions.

Know Guidelines for Direct Supervision

Incident-to services must be performed under the direct supervision of the physician. CMS states that “Direct supervision in the office setting does not mean that the physician must be present in the same room with his or her aide. However, the physician must be present in the office suite and immediately available to provide assistance and direction throughout the time the aide is performing services.”
