There are a lot of concerns related to “incident-to“ billing. However, for physician practices, “incident-to” billing is a money maker, which, in the world, of sub-par Medicare reimbursement rates is a minute ray of sunshine in an otherwise eclipsed land. Auditors argue that there are fraud and abuse concerns because practices ignore or are confused about the rules and bill everything “incident-to“regardless of the conditions being met. This can result in a nasty audit, as well as substantial fines, penalties, and attorneys’ fees. If you bill “incident-to,” just follow the rules…unless those rules are eliminated. Until possible elimination, keep up with the rules, which can differ depending on the auditor in the region.
Recently, people have been pushing for Medicare reform to include disallowing nurse practitioners (NPs) and physician assistants (PAs) from billing “incident-to.” Proponents of the suggested amendment claims that the recommendation would save the Medicare program money — approximately $50 to $250 million annually and just under $1 billion over 5 years.
The number of NPs who bill Medicare has more than doubled, from 52,000 to 130,000 from 2010 to 2017
What is “incident-to” billing?
In colloquialism, “incident-to” billing allows non-physician providers (NPPs) to report services “as if” they were performed by a physician. The NPP stands in the shoes of the physician. The advantage is that, under Medicare rules, covered services provided by NPPs typically are reimbursed at 85% of the fee schedule amount; whereas, services properly reported “incident-to” are reimbursed at the full fee schedule value.
In legalize, “incident-to” services under §1861(s)(2)(A) of the Social Security Act are provided by NPPs as a part of the services provided directly by the physician, but billed as if they were in fact performed by the physician. Several, legal, threshold requirements must be satisfied before billing eligibility for these services is established.
Billing using “incident-to” can be a huge money-maker for providers. If billed incorrectly, it can also be a provider’s financial downfall.
“Incident-to” billing can only apply to established patients. Not new patients. Not consults. The other non-negotiable factor is that the physician who is supervising must be on-site. Not a phone call away. Not grabbing a burger at a local eatery. On-site. Although with hospitals, the cafeteria is a viable option. I foresee, in the future, telehealth and Skype may change this on-site requirement. The incident-to rules also require that the services be part of a patient’s normal course of treatment. The rules require that the physician remains actively involved in the patient’s course of treatment. There must be direct supervision. Direct supervision = on-site. The following services cannot be billed as “incident-to:”
- new patient visits
- visits in which an established patient is seen for a new problem
- visits in which the treatment provided or prescribed is not a part of the treatment plan established by a physician
- services provided in the hospital or ambulatory surgery center.
Do not confuse “incident-to” with Medicare patients versus Medicaid patients. MediCAID’s regulations for the coverage of MD services vary significantly than Medicare’s rules and requires direct contact with the patient with exceptions.
Here is a question that I often get: “When billing “incident-to,” do you bill “incident to” the physician who is physically on-site that day or the physician who is overseeing that patient’s care? Both physicians are in the same group and it is billed under the Group NPI, but not sure which physician to reference for “incident-to.”
Answer: Bill under the MD who is on-site. This was addressed by the Center for Medicare and Medicaid Services (CMS) in the 2016 Physician Fee Schedule Final Rule.
The Medicare Benefit Policy Manual addresses the “incident-to” rules for each provider type and in any scenario:
- Section 60 contains policies for services furnished incident to physicians’ services in the physician’s office.
- Chapter 6, section 20.5 enumerates the policies for therapeutic services furnished “incident-to” physicians’ services in the hospital outpatient setting.
- Section 80 states the policies for diagnostic tests in the physician’s office
- Chapter 6, section 20.4 lists the policies for diagnostic tests furnished in the hospital outpatient setting.
Drug Administration under “incident-to”
“The Medicare program provides limited benefits for outpatient prescription drugs. The program covers drugs that are furnished “incident to” a physician’s service provided that the drugs are not usually self-administered by the patients who take them.” Medicare Benefit Policy Manual, 50.2. Injectable drugs, including intravenously administered drugs, are typically eligible for inclusion under the “incident-to” benefit.
The Medicare Administrative Contracts (MACs) (or – auditors) must fully explain the process they will use to determine whether a drug is usually self-administered and thus does not meet the “incident-to” benefit category. The MACs must publish a list of the injectable drugs that are subject to the self-administered exclusion. If there is discrepancy amongst the MACs, a lawsuit could help.
In order to meet all the general requirements for coverage under the “incident-to” provision, an FDA approved drug or biological must:
- Be of a form that is not usually self-administered;
- Must be furnished by a physician; and
- Must be administered by the physician, or by auxiliary personnel employed by the physician and under the physician’s personal supervision
The charge, if any, for the drug or biological must be included in the physician’s bill, and the cost of the drug or biological must represent an expense to the physician.
“Incident-to” billing is subject to elimination. The difference in billing “incident-to” is a 100% reimbursement rate versus an 85% reimbursement rate. That 15% difference cannot be passed onto the Medicare recipients.
While “incident-to” billing continues to be allowed, it is imperative to keep up with the ever changing rules.
