Medicare site-neutral payment reform is segmenting medical office real estate by site of service. Provider revenue changes when payment rules take effect, but rent adjusts at lease expiration. This timing wedge delays the property-level shock until renewal.
On-campus hospital outpatient space and ASC-anchored properties gain relative value. Off-campus hospital-leased infusion and imaging space faces weaker economics, footprint rationalization, and wider cap rates.
Payment Policy
The 2026 final rule, CMS-1834-FC, expanded site-neutral payment to drug administration and infusion services in excepted off-campus provider-based departments. The facility payment falls to approximately 40% of the standard OPPS rate. On-campus departments within 250 yards of the hospital retain full OPPS payment. Rural sole community hospitals and critical access hospitals are exempt. CMS projects approximately $290 million in CY2026 savings.
The 2027 proposed rule, CMS-1850-P, extends site-neutral payment to non-contrast imaging. CMS estimates a $260 million CY2027 reduction and $7.2 billion to $10 billion over ten years. It also proposes reducing 340B drug reimbursement from ASP + 6% to ASP − 33.4%, affecting approximately $4.55 billion to $4.85 billion in drug spending. The annual 340B remedy adjustment rises from 0.5% to 3.0%, completing the $7.8 billion recovery by CY2029.
The proposed 2027 physician fee schedule cuts the conversion factor for non-APM participants by 1.68% after temporary 2.50% statutory relief expires.
| Policy | Revenue exposure | Real estate effect |
|---|---|---|
| 2026 site-neutral drug administration | Excepted off-campus hospital departments | Negative for hospital-leased infusion and oncology space; positive for freestanding operators |
| 2027 proposed site-neutral imaging | Off-campus hospital imaging | Volume shifts toward freestanding imaging |
| 2027 proposed 340B reduction | 340B hospitals and drug-heavy outpatient programs | Weakens subsidized satellite clinics; favors procedure-heavy on-campus space |
| 2027 proposed conversion-factor cut | Non-APM physician practices | Thinner rent coverage and faster platform consolidation |
| Inpatient-only list removal and ASC expansion | Procedures migrate to outpatient settings | Positive for ASCs and procedural suites |
| Medicare Advantage network narrowing | Out-of-network providers | Concentrates volume within approved sites |
| Medicaid eligibility restrictions | Medicaid-heavy providers | Higher uninsured volume and bad debt |
The aggregate site-neutral savings are small relative to total Medicare outpatient spending but concentrated in service lines that support off-campus expansion. Each closed payment differential reduces the economics of hospital practice acquisitions, outpatient drug programs, and satellite clinics.
The Timing Wedge
Provider revenue resets on the effective date. Rent usually represents a mid-single-digit share of practice revenue. Tenants often cut staffing, hours, and service lines before seeking rent relief. Relocation requires new build-outs, equipment installation, licensing, and patient retention. Hospital clinics may also lose provider-based status by moving.
| Revenue change | EBITDAR | Rent coverage |
|---|---|---|
| 0% | 21 | 3.5x |
| −3% | 18 | 3.0x |
| −10% | 11 | 1.8x |
A 3% revenue decline leaves rent payable but reduces tolerance for above-market renewal terms. A 10% decline can place the lease on a renewal watchlist.
Contractual escalators near 3% compound the pressure when market rent grows about 1.3%. Over five years, in-place rent moves approximately 8.7% above the market-growth path. Renewal spreads compress even before reimbursement pressure affects tenant decisions.
Asset Segmentation
| Asset class | Volume | Rent capacity | Outlook |
|---|---|---|---|
| On-campus hospital outpatient MOB | Rising | Stable to rising | Strong |
| ASC-anchored MOB | Rising | High, with substantial improvement costs | Strong |
| Independent practices with ancillaries in commercial-heavy suburbs | Rising | Stable | Modestly positive |
| Primary care and low-ancillary practices in Medicaid-heavy markets | Flat to rising | Weak | Negative for rent growth and retention |
| Off-campus hospital infusion, oncology, and basic imaging clinics | Declining or relocating | Declining | Weak |
| Medicare Advantage-linked primary care clinics | Volatile | Strong parent credit, abrupt footprint changes | High churn |
The historical hospital-affiliated rent premium came from system credit, referral alignment, campus location, and hospital outpatient reimbursement. Policy selectively erodes the reimbursement component.
On-campus exemption becomes a regulatory asset reinforced by scarce campus-adjacent land. Off-campus system credit still protects contractual payment, but service-line economics determine whether the tenant renews. The primary risks are non-renewal, downsizing, subleasing, shorter terms, and termination rights.
Independent practices gain relative competitiveness as hospital acquisition incentives weaken, but they retain physician-level credit exposure and private-equity leverage.
Renewal and Valuation Effects
Reported NOI remains insulated by contractual escalators, staggered expirations, occupancy gains, and parent guarantees. Deteriorating tenant economics therefore appear first in renewal terms rather than current occupancy.
| Metric | Selective divergence | Portfolio-wide stress |
|---|---|---|
| Retention | 78% | 70% |
| Renewal cash spread | 0% | −5% |
| Annual same-store NOI drag | ≈ −0.5 point | ≈ −1.9 points |
| Same-store NOI growth | ≈ 3.0% | ≈ 1.6% |
| NOI versus baseline after 2027–2029 cohorts | ≈ −1% | ≈ −3% |
| Value effect, including 25 bp stress cap-rate widening from 6.5% | ≈ −1% | ≈ −7% |
Tenant-improvement and leasing-commission costs add further pressure. If 25% of annual base rent behaves according to the stress case, the implied NOI effect is approximately −0.8%.
The larger valuation risk is cap-rate segmentation. Exposed off-campus properties should price wider than protected on-campus assets even when portfolio-level NOI remains positive.
Monitoring and Falsification
The transmission chain is:
Payment policy → provider margin → footprint decision → retention, renewal spread, and tenant costs → NOI and valuation
The thesis fails if on-campus and off-campus renewal spreads remain aligned, weighted renewal terms stay at seven years or longer, and retention remains above 80% through the 2027 cohort.
Quarterly indicators:
- Retention by renewal cohort
- Weighted renewal term
- Tenant improvements and leasing commissions per renewed square foot
- Free rent and termination rights
- Subleasing and tenant watchlists
- Health-system capital expenditure plans
- Separate on-campus and off-campus leasing spreads
Strategic Consequence
Medicare payment policy is repricing medical office real estate through site-of-service economics. Revenue resets precede lease repricing, so the shock emerges at renewal rather than through immediate occupancy losses.
On-campus outpatient and ASC-anchored properties gain relative value. Off-campus hospital infusion and imaging properties face weaker retention, renewal spreads, and valuation. The 2027 through 2029 renewal cohorts will determine the magnitude, while the 2026 final rule has already established the direction.
