TL;DR — Key Takeaways

• Fair market value is the price an unrelated third party would pay in an arm’s-length transaction for the same service. It’s the reference point for most healthcare compensation regulation.
• FMV applies to MSO management fees, medical director fees, physician compensation arrangements, real estate leases between healthcare entities, and any service contract between parties in a position to refer.
• FMV protects against fee-splitting (BPC § 650), federal anti-kickback violations, and Stark law violations. It’s also relevant to SB 351 compliance.
• FMV is established through a defensible methodology — market comparables, cost build-up, or income approach — typically documented in a written opinion.
• FMV is a range, not a single number. Compensation within the documented range is generally defensible; compensation outside it requires explanation.

Why Is Fair Market Value Required in California Healthcare Compensation Arrangements?

FMV is the operational standard that connects healthcare contracts to multiple regulatory regimes. Without it, compensation arrangements can be characterized as kickbacks, fee-splits, or disguised payments for referrals.

California Business and Professions Code § 650 prohibits compensation in exchange for referrals or as a share of professional fees. FMV documentation supports the position that compensation is for genuine services, not for referrals.

Federal anti-kickback statute (42 U.S.C. § 1320a-7b). Multiple AKS safe harbors require FMV (personal services, space rental, equipment rental, management contracts).

Stark law (42 U.S.C. § 1395nn). Physician self-referral exceptions for personal services, fair market value compensation, rental of office space, and others all require FMV.

SB 351 (effective 2026). While SB 351 does not directly impose an FMV requirement, MSO compensation in PE-backed arrangements is more likely to face scrutiny when not at FMV.

FMV is the common thread. Compensation set at FMV passes most regulatory tests; compensation that deviates without explanation fails them.

How Is Fair Market Value Determined for a Medical Director Agreement?

Medical director compensation has been a frequent enforcement target because it’s an arrangement where compensation can easily be inflated to disguise referral incentives. Determining FMV for a medical director agreement involves several steps.

Define the role. The medical director’s specific duties — quality oversight, policy review, supervision of clinical staff, attendance at meetings, on-call responsibilities. The role should be described in detail in the agreement.

Quantify the time. Estimated hours per month based on the duties described. Common medical director arrangements range from a few hours per month (simple oversight) to half-time or more (complex multi-site programs).

Identify market comparables. Hourly rates for medical directors in similar roles, by specialty and region. Several published surveys (MGMA, Sullivan Cotter, ECG, Hay Group) provide ranges. Specialty matters: a cardiothoracic surgeon medical director rate is much higher than an internal medicine medical director rate.

Calculate FMV compensation. Hours × hourly rate, with adjustments for any unique elements of the role.

Document. A written FMV opinion or analysis memorializing the methodology, supporting data, and conclusion. The agreement itself should reference the FMV analysis.

Common medical director hourly rates run from $200 to $600 depending on specialty and market, though values can be higher for highly specialized roles.

What Happens if an MSO Fee Is Not Set at Fair Market Value?

Above-FMV compensation creates exposure. Below-FMV is also problematic in some contexts.

Above-FMV. The excess compensation can be recharacterized as a kickback, a disguised dividend (creating tax issues), a payment for referrals (BPC § 650 violation, AKS violation if federal program patients are involved), or interference with clinical judgment (SB 351 risk for PE-backed entities). The remedy is usually retrospective: fees are clawed back, contracts are voided, civil and criminal exposure attaches, and licensure consequences may follow for involved providers.

Below-FMV. Less common but possible. If a physician refers patients to an entity that provides services at below-FMV rates, the discount can be characterized as remuneration for the referral. Common in physician-hospital relationships and physician-supplier relationships.

At-FMV but undocumented. Compensation that happens to be at FMV but lacks supporting documentation is difficult to defend. The defense to a regulatory challenge starts with the documentation. Without it, the FMV position is just an assertion.

Can Physician Compensation Be Tied to Revenue or Referrals in California?

Compensation tied to a physician’s own revenue (production-based compensation, eat-what-you-treat) is generally permitted. Most California medical groups use some form of production-based compensation: collections from a physician’s services attributed to that physician, or a percentage of work RVUs.

Compensation tied to revenue from other physicians’ referrals or to overall practice profitability creates more complex analysis. AKS, Stark, and California fee-splitting all scrutinize compensation that varies based on referrals or volume of designated services.

Permitted (generally): Compensation based on the physician’s own personally performed services. Compensation based on collections directly attributable to the physician.

Scrutinized: Compensation based on practice profitability where the physician influences referrals to ancillaries. Bonuses tied to volume of services provided by other clinicians. Compensation tied to formulary or referral patterns.

Generally prohibited: Fixed percentage of any revenue stream the physician influences through referrals to designated services (Stark and AKS issue) or compensation in exchange for sending patients to another provider (§ 650 issue).

How Does Fair Market Value Protect Against Anti-Kickback Violations?

AKS prohibits remuneration intended to induce referrals of items or services payable by federal healthcare programs. FMV is a key element of the safe harbors that immunize specific structures.

Personal services and management contracts safe harbor. Requires that compensation be at FMV, not vary based on referrals, be set in advance, and meet other criteria.

Space rental safe harbor. Requires FMV rent, not varying based on referrals, lasting at least one year, and other terms.

ASC investment safe harbor. Requires investment terms not tied to referrals, plus FMV consideration if assets are transferred.

Bona fide employment safe harbor. Compensation must be FMV.

Without FMV, the safe harbors are unavailable, and the arrangement is analyzed under the general AKS standard, which considers whether one purpose of the compensation is to induce referrals. The intent analysis is more uncertain than safe harbor protection.

FMV documentation also protects against False Claims Act exposure for federal program billing tied to the arrangement.

How to Document Fair Market Value

Engage a qualified valuation firm. Healthcare-specific valuation is a specialty. Generic business valuation experts may miss healthcare regulatory considerations. Firms that specialize in healthcare FMV (HealthCare Appraisers, ECG, VMG, Pinnacle, others) have current data and methodology familiar to regulators.

Define the scope clearly. The valuation engagement should specify the services being valued, the parties, the time period, and the regulatory purpose (AKS safe harbor, Stark exception, BPC § 650 support).

Use multiple methodologies where possible. Market approach, income approach, cost approach. Cross-checking across methods strengthens the conclusion.

Document the conclusion in writing. A written FMV opinion or memorandum is the deliverable. Some arrangements use an FMV memorandum (shorter, less formal); higher-risk arrangements warrant a full FMV opinion.

Refresh periodically. FMV changes over time. A medical director rate set in 2020 may be below current FMV in 2026. Refresh the analysis when contracts renew, when the role changes, or every two to three years for ongoing arrangements.

Maintain in the file. When regulators investigate, the first document they request is the FMV documentation. Production-ready files reduce risk.
