3.3 The Physician Self-Referral Law (Stark Law) & Exceptions

3.3 The Physician Self-Referral Law (Stark Law) & Exceptions

Overview of the Physician Self-Referral Law (42 U.S.C. § 1395nn)

The Physician Self-Referral Law, commonly known as the Stark Law (codified at 42 U.S.C. § 1395nn and 42 C.F.R. Part 411), is a civil, non-criminal statute governing physician financial relationships. Authored by Congressman Pete Stark, the law prohibits a physician (or an immediate family member) who has a financial relationship with an entity from making a referral to that entity for the furnishing of Designated Health Services (DHS) for which payment may be made under Medicare or Medicaid.

Furthermore, if a prohibited financial relationship exists and no statutory exception is satisfied, the entity may not submit a claim or bill to Medicare, Medicaid, or any third-party payer for DHS rendered pursuant to the prohibited referral.

Strict Liability Standard: No Intent Required

Unlike the Anti-Kickback Statute, the Stark Law is a strict liability statute.

• No Intent Required: The government does not need to prove bad faith, corrupt intent, or an intent to induce referrals.
• Technical Violations: A minor administrative failure—such as an unexecuted employment contract, an expired lease where holdover rent continues, or paying a physician $5 above documented Fair Market Value (FMV)—instantly destroys compliance with an exception.
• Disallowed Claims: Once exception protection is lost, every single referral made by that physician for DHS to that entity is strictly illegal, rendering all associated claims unbillable and subject to mandatory refund.

Designated Health Services (DHS)

Stark Law applies exclusively to referrals for Designated Health Services (DHS). The 10 statutory categories of DHS under 42 U.S.C. § 1395nn(h)(6) are:

1. Clinical laboratory services.
2. Physical therapy, occupational therapy, and speech-language pathology services.
3. Radiology and certain other imaging services (MRI, CT, PET, nuclear medicine, ultrasound).
4. Radiation therapy services and supplies.
5. Durable medical equipment (DME) and supplies.
6. Parenteral and enteral nutrients, equipment, and supplies.
7. Prosthetics, orthotics, and prosthetic devices and supplies.
8. Home health services.
9. Outpatient prescription drugs.
10. Inpatient and outpatient hospital services.

Financial Relationships: Ownership vs. Compensation

A financial relationship under Stark Law exists in one of two statutory forms:

                    ┌────────────────────────────────────────────────────────┐
                    │              Stark Financial Relationships             │

Key Statutory & Regulatory Exceptions

Because Stark Law is a strict liability prohibition, an arrangement must fit completely within a statutory or regulatory exception to be legal. Key exceptions include:

1. In-Office Ancillary Services Exception (IOASE - 42 C.F.R. § 411.355(b))

Permits physician group practices to furnish certain DHS (e.g., clinical lab, x-rays, ultrasound, PT) within their office suite without violating Stark, provided three criteria are met:

• Location: Services furnished in the same building where the group practice provides routine non-DHS physician services.
• Supervision: Services supervised directly by a member of the group practice or an employee physician.
• Billing: Services billed by the group practice using its own tax ID.

2. Fair Market Value Compensation Exception (42 C.F.R. § 411.357(l))

Protects compensation arrangements between a DHS entity and a physician if:

• Documented in writing, signed by the parties, covering specific services.
• Specifies timeframe and compensation set in advance at Fair Market Value (FMV).
• Does not factor in volume or value of referrals or other business generated.
• Arrangement is commercially reasonable even if no referrals were made.

3. Non-Monetary Compensation Cap (42 C.F.R. § 411.357(k))

Allows DHS entities (e.g., hospitals) to provide minor non-monetary items (holiday gifts, CME dinners) to physicians without violating Stark, provided:

• Aggregate value does not exceed the annual statutory cap (indexed for inflation; approximately $500 per calendar year per physician).
• Compensation is not solicited by the physician and does not factor referral volume/value.

Real-World Healthcare Compliance Scenario

Scenario: A hospital employs an orthopedic surgeon under a written employment agreement paying a base salary plus a quarterly productivity bonus equal to 15% of the hospital's facility fees generated from surgeries performed by the surgeon in the hospital's outpatient surgical department. An internal compliance audit flags this bonus structure.

Compliance Analysis: Under Stark Law (42 U.S.C. § 1395nn), hospital outpatient services are a Designated Health Service (DHS). While employed physicians may receive bonuses based on personally performed work, Stark explicitly prohibits compensation tied to the volume or value of facility fees or indirect referrals generated for the hospital. Because the bonus factors in hospital facility fees (DHS), the agreement fails the Bona Fide Employment Exception. Under strict liability, all surgical referrals by the surgeon to the hospital constitute illegal Stark referrals, rendering all hospital Medicare facility claims unbillable and subject to FCA liability.
