What You Need to Know About P-Stim Audits and Investigations

Experienced Former DOJ-Prosecutors Protecting YOUR Professional License

Across the United States, physician and chiropractic offices are being targeted for submitting false Medicare claims for so-called P-Stims. Federal authorities such as the Centers for Medicare and Medicaid (CMS), Medicare intermediaries, the U.S. Department of Health and Human Services (HHS), the Office of Inspector General (OIG), and Medicare prosecutors at the U.S. Attorney’s Office have begun scrutinizing a broad number of clinics in an effort to recoup and sanction erroneous billing practices. If your practice is under audit, you should immediately consult with experienced counsel to make sure your license and your practice stay protected.

When it comes to healthcare fraud defense, there simply is no firm like Oberheiden, P.C.

Billing and Coding P-Stim L8679 (Stivax)

In assisting Medicare providers, physician offices, chiropractic, and wellness clinics across the United States, Oberheiden, P.C. lawyers noticed that most P-Stim audits center around three billing instances described below.

  • Billing for P-Stim under HCPCS Code L8679: The American Medical Association defines code L8679 as “Implantable neurostimulator, pulse generator.” However, the government takes the position that the P-stim application does not qualify as an “implantable” device. Instead, the various types of P-stims are applied as devices employing acupuncture needles attached to electrodes that are being applied to a patient’s ear through simple bandages.
  • Billing CPT Code 64555 for the Actual Application of the P-Stim to the Patient. The American Medical Association defines Code 64555 as a “percutaneous implantation of neurostimulator electrode array, peripheral nerve (excludes sacral nerve). CMS explains that doctors using the P-stim without true electrodes in need of implantation (but mere acupuncture needles) should not bill under Code 64555.
  • Billing Modifier 25. A number of providers have added Modifier 25 to Code L8679 procedures despite the fact that no additional medical treatment or complaint was recorded. Per CMS, the purpose of Modifier 25, however, is to document and capture a “significant, separately identifiable E/M service” provided by the same physician/qualified nonphysician practitioner “to the same patient on the same day as another procedure or other service with a global fee period.”

What Could Happen in Your Case

Medicare Audits

Your practice may become subject to a Medicare audit. Several types of Medicare audits exist. In general, regionally spread throughout the United States, Medicare Administrative Contractors (MACs) and Recovery Audit Contractors (RACs) are tasked to discover medically unnecessary procedures and unjust reimbursement (“overpayments”). Similarly, Zone Program Integrity Contractors (ZPICs) investigate potential fraud by referring providers to the Department of Health and Human Services (HHS) and the Office of Inspector General (OIG), the two agencies prosecuting healthcare fraud on behalf of the Department of Justice. There are two ways to get on the CMS radar. One way is merely bad luck when your practice is picked by a somewhat random computer analysis; the other way is a request for records when CMS already has information to believe that your practice did something wrong.

License Suspension or Revocation

Paying back money may be one thing, but losing your license is the ultimate risk. If the government comes back with a finding of Medicare fraud, there is a real chance that your professional state board will be notified, and, if notified, will take action against your license. Don’t let this happen. There are many ways to avoid a finding of and an admission of healthcare fraud. The Oberheiden, P.C. track record in Medicare audits is easily summarized: not one provider has lost his/her license.

False Claims Act Investigation (31 U.S.C. 3729-3733)

The False Claims Act (FCA) sanctions inappropriate billing practices and utilization of wrong codes. Specifically, the federal False Claims Act imposes severe penalties for submitting false or fraudulent claims to CMS. False or fraudulent in this context means any claim that was submitted in violation of established billing practices. Importantly, violations of the FCA do not have to be willful or intentional. It is sufficient to submit a claim when the provider “should have known” that the code used was incorrect. Each claim submission for P-Stim reimbursement could amount to an FCA violation. Because the government is not required to prove intent, the FCA is among the most widely utilized federal healthcare fraud statutes. If found liable, providers are exposed to a penalty of up to $ 11,000 per claim submission, additional fines, and recoupments. Arguably, the P-stim code L8679 should have been coded as A9270, that is as a non-covered item or service.

OIG Subpoena: Department of Health and Human Services (HHS)

A common tool to investigate healthcare providers is by issuing so-called OIG subpoenas. The OIG, the Office of Inspector General, and the Department of Health and Human Services (HHS) are the two enforcement arms of the Department of Justice in healthcare cases. If you receive an OIG subpoena or if OIG-HHS agents visit your practice, you are affirmatively under federal healthcare fraud investigation. Often times, OIG agents will request patient files or detailed billing records to establish that you did not abide by the applicable rules. OIG subpoenas require skilled and proven defense techniques. A mere production of the files (or, worse, fighting the subpoena) is the most common mistake attorneys make. Oberheiden, P.C. lawyers will navigate your practice through the process relying on the experience of many hundreds of OIG investigations handled, as former Department of Justice prosecutors and as healthcare fraud defense lawyers for clients across the country.

The attorneys at Oberheiden, P.C. have been at the forefront of P-Stim cases and we have helped many hard-working doctors successfully defend their practice and their license. If you have questions or concerns about P-Stim cases, please call us today and request a free consultation with one of our experienced former Medicare prosecutors.

Can the Case Be Criminal?

Yes. Every healthcare fraud investigation has the potential for criminal prosecution. Pursuant to 18 U.S.C. § 1347, a person is guilty of healthcare fraud if the government proves beyond a reasonable doubt that the person:

  • Knowingly and willfully executes, or attempts to execute, a scheme or artifice
  • To defraud any healthcare benefit program or obtain, by means, of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program
  • In connection with the delivery of or payment for healthcare benefits, items, or services.

Although the nature of P-Stim cases is predominantly civil (and not criminal), in two instances P-Stim audits can turn into a referral to the U.S. Attorney’s Office.

Bad Handling. As attorneys, we see all the time how a simple audit is underestimated or addressed incorrectly. What begins innocently with a request for some patient charts, can quickly turn into something bigger than necessary because providers decide to “handle” the matter themselves or with the assistance of inexperienced counsel. To be clear, any Medicare audit has the potential for a referral to law enforcement. Mistakes made at the entry level of an audit can hardly be undone. Statements to CMS, the casual handing over of files, or, worse, retroactive manipulation of patient records all have the potential for disaster. From our work as federal healthcare fraud prosecutors at the Department of Justice, we have seen over and over how a mishandled audit can lead to a referral for prosecution. Don’t make that mistake! Recognize that you are not a lawyer and that the best real estate lawyer, or DUI lawyer, or even corporate healthcare lawyer may lack the specific experience dealing with federal law enforcement authorities and may not have the necessary track record of resolving audits at the first level.

Egregious Practice. A second way the case can turn criminal is when the initial finding demonstrates an egregious, abusive, systematic, or deliberate wrongdoing. Even in those instances, the investigation may begin with a simple audit. The best federal defense lawyers will immediately recognize the problem and initiate effective defense mechanisms to bring things in order before the government continues its investigation. Don’t allow the government time to build a case against you. Often, what begins apparently simple as a ZPIC audit, OIG subpoena, or other form of governmental inquiry, can quickly get out of control. Don’t let this happen!

FAQs: Federal Prosecutions and Audits in Connection with Code L8679

Q: I Just Learned that My Practice Is Under Audit Related to P-Stims. Will I Lose My License?

If your practice is under audit or investigation, you need to make sure that the case is not turning into a referral to the U.S. Attorney’s Office. CMS is working closely with state professional boards and it is of critical importance for you to be represented by the best legal counsel to navigate you through the audit and to make sure that your license remains protected.

Q: What Are Criminal Penalties in P-Stim Cases?

The penalties for federal healthcare fraud depend on the specific statute (or statutes) at issue. Most P-Stim cases involve allegations under the False Claims Act. In a civil FCA case, the penalties can include recoupments, treble damages, fines, program exclusion, and other financial penalties. In a criminal P-Stim case, the penalties can include:

  • Felony Conviction
  • Criminal fines
  • Up to 10 years of federal imprisonment for each count of healthcare fraud
  • Up to 20 years of federal imprisonment for each count involving serious bodily injury to a patient
  • A life sentence for healthcare fraud resulting in a patient fatality

When Should I Hire an Attorney?

If your practice utilized Code L8679, you should speak to a lawyer right away. Sound legal advice from experienced attorneys is warranted to avoid a referral to the U.S. Attorney’s Office. Mistakes made in routine or specific Medicare audits will lead to secondary or tertiary review or a referral to DOJ. If your practice received a Medicare audit request or if CMS agents came to your office to interview you (even more intimidating), please call the former Medicare Prosecutors of Oberheiden, P.C. immediately. We will analyze the audit request and discuss the significance of the investigation with you in a free and confidential consultation. As we have for all of our providers, we will PROTECT your license and will make sure to conclude the audit before it gets to another stage.

Which Attorney Will Handle My Case?
