Block Leasing of Group Practice Facilities – Anti-Kickback Statute Risks

By John Fisher, JD, CHC, CCEP

Client Alert – Healthcare Block Leasing, Anti-Kickback Statute Risks, and AKS Safe Harbor Compliance

The AKS prohibits offering, paying, soliciting, or receiving remuneration to induce referrals of items or services reimbursable by Medicare, Medicaid, or other federal healthcare programs. For healthcare organizations and law firm clients, compliant block leasing requires careful attention to fair market value, commercial reasonableness, written lease terms, actual utilization, and applicable AKS safe harbors.

Anti-Kickback Statute Risks in Healthcare Block Leasing Arrangements

The AKS is a broad criminal statute that applies to both sides of a leasing transaction: the facility owner and the group practice. If a lease is structured in a manner that provides payments above or below fair market value, or includes terms that are contingent upon referral volume or value, it may be deemed as an unlawful kickback. Regulatory scrutiny is heightened when the leased space is used in connection with services billable to Medicare, Medicaid, or other federal programs.

Healthcare Real Estate Lease Compliance Pitfalls Under the AKS

• Below-Market Rent: Offering space at rates below fair market value can be interpreted as remuneration intended to induce referrals.
• Volume or Value of Referrals: Lease terms that fluctuate based on the number of patients referred or services rendered may violate the AKS.
• Exclusive Use Provisions: Block leasing that grants exclusive use to a practice without proper safeguards can raise suspicions of preferential treatment.
• Lack of Documentation: Failure to document the basis for rent calculations and fair market value assessments undermines compliance defenses.

AKS Space Rental Safe Harbor and Healthcare Lease Compliance Strategies

AKS Safe Harbors for Healthcare Block Leasing: Space, Equipment, and Services

Block leasing arrangements may implicate more than one AKS safe harbor depending on what is included in the arrangement. The most relevant protections generally involve space rental, equipment rental, and personal services or management contracts. Each safe harbor must be satisfied in full to provide protection; failure to meet every element does not automatically make an arrangement unlawful, but it means the parties must rely on a facts-and-circumstances risk analysis.

Space Rental, Equipment Rental, and Services Safe Harbor Requirements

• Space Rental Safe Harbor: This is typically the primary safe harbor for block leasing. The lease should be in writing, signed by the parties, cover all space used, specify the premises and schedule for part-time use, have a term of at least one year, set rent in advance, reflect fair market value, and avoid taking into account the volume or value of referrals or other business generated between the parties.
• Equipment Rental Safe Harbor: If the arrangement includes exam equipment, diagnostic equipment, furniture, technology, or other equipment access, the parties should evaluate the equipment rental safe harbor separately. The agreement should identify the equipment, establish compensation in advance, require a commercially reasonable term, and ensure payments reflect fair market value without regard to referrals.
• Personal Services and Management Contracts Safe Harbor: If the block lease includes staffing, administrative support, scheduling, billing assistance, medical director duties, or management services, the services component may need separate safe harbor analysis. Compensation should be set in advance, commercially reasonable, consistent with fair market value, and not determined in a manner that rewards referral volume or value.
• Practical Structuring Point: A single block leasing arrangement may need to be separated into distinct components—space, equipment, supplies, and services—so that each component can be documented, valued, and tested against the most relevant safe harbor. Bundling all items into one undifferentiated fee can make compliance more difficult to demonstrate.

Healthcare Block Leasing Examples for AKS Safe Harbor Analysis

Examples: The following examples show how different safe harbors may apply to common block leasing structures:

• Space-Only Block Lease: A physician group leases two exam rooms every Tuesday and Thursday afternoon under a signed one-year agreement. The lease identifies the rooms, specifies the recurring schedule, sets rent in advance based on fair market value, and does not vary with referrals or patient volume.
• Space Plus Equipment Access: A practice leases procedure space and also receives access to specialized diagnostic equipment during its block time. The parties document the space rental and equipment rental components separately, value each component independently, and ensure compensation is fixed in advance and commercially reasonable.
• Space Plus Staffing Support: A facility provides front-desk coverage, room turnover, or clinical support during the leased block. The services are described in writing, priced separately from rent, and supported by a fair market value analysis that does not account for referrals between the parties.
• Integrated Arrangement Requiring Multiple Analyses: A block lease includes exam rooms, equipment, supplies, scheduling assistance, and administrative support. The parties avoid a single bundled fee and instead identify the relevant safe harbor for each component, maintain valuation support, and periodically confirm actual use matches the written terms.
• Arrangement Outside a Safe Harbor: A tenant leases more block time than it uses, pays a discounted rate, and receives informal staff support not described in the agreement. Even if the parties believe the arrangement has a legitimate purpose, the lack of clear documentation and valuation support would require careful facts-and-circumstances review.

Compliance Tips for AKS Safe Harbor Protection in Healthcare Leases

Compliance Tips: To strengthen reliance on applicable safe harbors, parties should build the following safeguards into the transaction file and ongoing monitoring process:

• Map Each Component to a Safe Harbor: Identify whether the arrangement includes space, equipment, services, supplies, or staffing, and analyze each component under the most relevant safe harbor instead of assuming the space rental safe harbor covers the entire relationship.
• Use Separate Pricing Support: Maintain valuation support for each component of value, including rent, equipment access, personnel support, and administrative services, so the parties can show compensation was set in advance and consistent with fair market value.
• Specify Part-Time Use Clearly: For part-time or periodic use, describe the exact premises, days, times, rooms, equipment, and services included in the block arrangement, and keep schedules consistent with actual operations.
• Avoid Referral-Based Negotiation Records: Keep negotiation materials focused on space needs, market rates, utilization, staffing, and operational efficiency; avoid language suggesting that lease terms were influenced by referral volume, referral value, or expected downstream revenue.
• Review Changes Before Implementation: Treat added rooms, expanded hours, new equipment access, additional staff support, or fee changes as amendments requiring renewed safe harbor analysis and documentation.
• Maintain a Complete Lease File: Keep the signed agreement, valuation materials, business justification, approval notes, utilization records, amendments, renewal analysis, and annual review documentation together in one compliance file.

Recent AKS Enforcement Trends for Healthcare Leasing and Referral-Source Arrangements

Recent enforcement activity reflects continued federal scrutiny of healthcare financial arrangements that may disguise referral incentives, even when an arrangement is described as a lease, service contract, administrative fee, or other facially legitimate business relationship. DOJ and OIG activity continues to emphasize that compliance analysis should look beyond labels and evaluate the economic substance of the arrangement: who benefits, whether the payment is commercially reasonable, whether the parties actually need the space or services, and whether the arrangement could influence federal healthcare program business. For block leasing arrangements, this means parties should expect careful review of whether the leased space is genuinely needed, whether rent is set in advance at fair market value, whether use is consistent with the written schedule, and whether the arrangement can be justified without regard to referrals.

Fair Market Value, Commercial Reasonableness, and Documentation Risks

• Fair Market Value Remains Central, but Not Sufficient by Itself: Enforcement matters continue to challenge arrangements where valuation support appears incomplete, inaccurate, or influenced by referral expectations. Even when rent appears to be within a market range, regulators may still examine whether the arrangement satisfies each applicable safe harbor element and whether the parties had a legitimate, non-referral business purpose.
• Commercial Reasonableness Is Increasingly Important: Fixed or pre-set compensation may draw scrutiny if the underlying business purpose is weak, the leased space exceeds what is reasonably necessary, or the arrangement duplicates resources the tenant already has. A lease that is technically fixed in price may still be problematic if the facts suggest the payment is designed to preserve or reward referral relationships.
• “Disguised Rent” Theories Remain a Risk: Recent healthcare fraud matters have included allegations that payments labeled as office space rent, phlebotomy support, administrative services, or technology access were actually intended to secure referrals. This trend is particularly relevant to block leasing because regulators may compare the stated rental purpose against actual utilization, staffing, equipment access, and patient flow.
• Documentation Gaps Create Risk: Missing needs analyses, inconsistent use schedules, unsupported rent calculations, expired agreements, or informal side understandings can undermine reliance on AKS safe harbor protections. Contemporaneous records are especially important where space is shared, used on a part-time basis, or leased in blocks rather than continuously occupied.
• Whistleblower and False Claims Act Exposure Is Significant: AKS concerns frequently surface through whistleblower complaints, audits, or internal compliance reviews. Because claims resulting from alleged kickbacks may be treated as false claims, a leasing issue can create exposure beyond the lease payments themselves, including repayment obligations, civil penalties, exclusion risk, and reputational harm.
• Referral-Source Leasing Requires Extra Care: Space or equipment arrangements between parties that refer to one another should be structured to satisfy each safe harbor element and reviewed periodically as utilization changes. Reviews should consider whether rent remains commercially reasonable, whether the leased blocks match actual operational needs, and whether any renewal, expansion, or modification could be viewed as tied to referral volume or value.

Healthcare Lease Risk Scenarios Involving Referrals and Block Time

Examples: The following scenarios illustrate how these enforcement themes may arise in practice:

• Nominal “Office Rent” for Referral Access: A laboratory or ancillary provider pays a physician practice a monthly amount labeled as rent for a small exam room or workstation, but the space is rarely used and the payment closely tracks the volume of tests ordered by the practice.
• Unused Block Time: A group practice leases recurring blocks of space at a facility but uses only a fraction of the scheduled time. If the facility is connected to referrals from that practice, regulators may question whether the lease reflects real operational need or functions as a financial benefit.
• Bundled Space and Support Services: A lease includes space, staff support, supplies, equipment access, and administrative services for a single fixed fee without allocating value among the components. This can make it difficult to show that each item is priced at fair market value and commercially reasonable.
• Renewal After Referral Growth: A landlord renews or expands a block lease shortly after the tenant’s referrals increase. Even if the new rent is fixed in advance, the timing and internal communications may create risk if they suggest the expanded lease was intended to reward referral activity.
• Documentation Mismatch: The written lease states that space is used three days per week, but access logs, staffing records, or billing patterns show materially different use. Inconsistent records can weaken the parties’ ability to demonstrate safe harbor compliance.

Recent AKS Case Studies for Healthcare Lease Compliance

Recent Case Studies: The following recent matters illustrate how enforcement agencies and whistleblowers continue to scrutinize arrangements that transfer value to referral sources, including arrangements framed as rent, support services, or fixed-fee business relationships:

• Laboratory Payments Disguised as Office Rent and Phlebotomy Support: In 2025, DOJ announced settlements with healthcare providers and laboratory marketers to resolve allegations that certain providers received remuneration from a laboratory in the form of purported office space rental, phlebotomy, and related payments in return for laboratory testing referrals. For block leasing, the matter underscores that rent labels will not control if the economic substance suggests payments were tied to referral generation rather than bona fide space or service needs.
• Free Support Services to a Referring Practice: In a 2024 hospital settlement, DOJ alleged that a health system provided free clinical support personnel to a private physician practice while the practice billed globally for services. Although not a traditional real estate lease, the case is instructive because it involved the provision of operational support to a referral source and reinforces the need to separately identify, value, and document any staffing or support included with leased space.
• Large Physician Compensation and Downstream Referral Allegations: Recent Stark Law and AKS-related False Claims Act matters involving hospital-physician compensation have focused on whether compensation exceeded fair market value or was intended to capture downstream referrals. The same enforcement logic can apply to leasing: regulators may examine whether the financial arrangement makes sense without the expected referral relationship.
• Flat-Fee Arrangements Still Require Substance Review: Recent OIG advisory guidance has emphasized that even fixed or flat annual fees may present AKS risk where the arrangement relieves a referral source of costs, affects competition, or lacks a commercially reasonable business justification. Block leases should therefore not rely solely on the fact that rent is fixed in advance; the arrangement should also be operationally necessary and commercially reasonable.
• Whistleblower-Driven Enforcement Remains Active: Several recent healthcare fraud matters began as qui tam complaints by insiders or former compliance personnel. For block leasing arrangements, this increases the importance of maintaining contemporaneous records showing fair market value, actual use, business need, and non-referral-based decision-making.

Healthcare Lease Compliance Takeaways for Reducing AKS Risk

Related Compliance Tips: To reduce enforcement risk, parties should consider the following practical steps when structuring or reviewing block leasing arrangements:

• Document Operational Need Before Signing: Prepare a short business justification explaining why the tenant needs the specific space, block schedule, equipment access, and support services included in the arrangement.
• Separate and Support Each Component of Value: If the arrangement includes space, equipment, staff, supplies, or administrative support, identify and value each component separately rather than relying on a single bundled fee.
• Use Independent Fair Market Value Support: Obtain valuation support that is independent of referral assumptions and keep the underlying methodology, comparable data, and approval materials with the lease file.
• Reconcile Written Terms to Actual Use: Periodically compare the lease schedule against access logs, room calendars, staffing records, billing data, and other utilization information to confirm that the arrangement is operating as documented.
• Control Renewal and Amendment Communications: Avoid emails or negotiation notes that connect rent, renewal terms, or expanded access to referral volume, anticipated referrals, or the value of federal healthcare program business.
• Build in Periodic Compliance Reviews: Review the lease at least annually and whenever utilization, ownership, referral patterns, or services materially change, and document any corrective action taken.

These enforcement trends point to a practical conclusion: safe harbor analysis should not be treated as a one-time drafting exercise. For law firm clients, the strongest compliance posture combines careful structuring at the outset with periodic review of how the arrangement operates in practice. The following guidance translates those enforcement themes into transaction-level steps counsel can use when drafting, reviewing, or monitoring block leasing arrangements.

Practical AKS Compliance Guidance for Healthcare Block Leasing

• Conduct thorough due diligence before entering block leasing arrangements.
• Engage qualified valuation experts to determine fair market rent.
• Ensure all lease terms are documented and comply with AKS safe harbor requirements.
• Monitor ongoing compliance, reconcile written lease terms to actual utilization, and review leases annually for regulatory changes, referral-pattern shifts, and changes in space, equipment, or staffing support.
• Train staff and physicians on AKS risks and reporting mechanisms.

Healthcare block leasing and referral-source real estate arrangements can provide operational benefits, but they also present substantial Anti-Kickback Statute, fair market value, commercial reasonableness, and documentation risks. Proactive healthcare lease compliance requires written agreements, independent valuation support, careful safe harbor analysis, actual-use monitoring, and ongoing review as referral patterns, services, equipment access, and space needs change.
