SNF Consolidated Billing Exclusions List 2026: What Can Be Billed Separately and What Cannot

Consolidated billing is one of the most operationally consequential Medicare rules in the skilled nursing facility setting and one of the most consistently misunderstood. Under Medicare Part A, the SNF is responsible for billing all services provided to a covered resident under a single consolidated claim. Outside providers cannot bill Medicare directly for services they deliver to Part A residents during the covered stay. That is the rule. The exclusions are the exceptions to it and knowing exactly what is on that exclusions list is what separates a compliant billing operation from one that is generating billing conflicts without knowing it.

This post covers the SNF consolidated billing exclusions as they apply in 2026, what the exclusions mean operationally, and where the most common compliance gaps occur when facilities and outside providers misread where the line sits.

The Consolidated Billing Rule: What It Requires

The Social Security Act requires that when a Medicare beneficiary is receiving care under a covered Part A SNF stay, the SNF must bill Medicare for all covered services provided during that stay including services provided by outside entities. The outside provider submits its charges to the SNF. The SNF includes those charges in the consolidated Part A claim. The outside provider gets paid by the SNF, not by Medicare directly.

The purpose of the rule is straightforward: Medicare pays the SNF a daily per-diem rate under PDPM that is intended to cover the full cost of post-acute care, including ancillary services. Allowing outside providers to bill Medicare separately for services already covered by the per-diem would result in Medicare paying twice once through the per-diem and once through the separate claim.

CMS publishes the list of excluded services – services that may be billed directly to Medicare by the rendering provider in the Medicare Benefit Policy Manual and updates it periodically. The exclusions exist because certain high-cost services are not considered bundled into the SNF per-diem and may be billed separately without creating a double-payment situation. Outside of those specific exclusions, the consolidated billing obligation applies to every covered service during every covered Part A Day.

What this means for your facility: The default rule is consolidation. The exclusions are the exception. Every outside service provided to a Part A resident should be evaluated against the exclusions list not assumed to be excludable because it comes from an outside provider or because the outside provider has historically billed Medicare directly.

The SNF Consolidated Billing Exclusions: What Can Be Billed Separately in 2026

CMS organizes the consolidated billing exclusions into specific service categories. The following categories represent services that may be billed separately by the rendering provider to Medicare during a covered Part A SNF stay.

Physician and Non-Physician Practitioner Professional Services

Physician services including evaluation and management visits, surgical procedures performed at the SNF, and other professional services billed under the physician’s own provider number are excluded from consolidated billing. When a physician, nurse practitioner, physician assistant, or clinical nurse specialist provides a professional service to a Part A resident, that professional bills Medicare Part B directly using the appropriate E&M or procedure codes under the practitioner’s NPI.

This exclusion covers the professional component of physician services only. The technical component of services performed at the SNF facility the use of the facility’s equipment, staff, or space may still fall under consolidated billing depending on the service. When a physician performs a procedure using the SNF’s equipment and nursing support, only the physician’s professional service is excluded the facility costs are consolidated into the per-diem.

Certain Ambulance Services

Ambulance transportation services are excluded from consolidated billing under specific circumstances. When an SNF resident requires emergency ambulance transportation to a hospital for a condition requiring emergency treatment, that ambulance service may be billed separately by the ambulance provider to Medicare. Non-emergency ambulance services scheduled for routine appointments are generally subject to consolidated billing and should be included in the SNF’s claim.

The emergency versus non-emergency distinction is the compliance-critical line in ambulance billing. Ambulance companies that routinely bill Medicare directly for all transportation of SNF residents without distinguishing between emergency and non-emergency transports create consolidated billing conflicts that generate payment adjustments and compliance exposure for the facility.

Certified Nurse-Midwife Services

Services provided by a certified nurse-midwife are excluded from consolidated billing and may be billed directly to Medicare by the CNM under their own provider number. This exclusion is relevant in the SNF setting primarily for female residents who continue to receive CNM services during a covered stay, though it applies regardless of the specific clinical context.

Qualified Psychologist Services

Services provided by a qualified psychologist specifically those that a psychologist is licensed to perform under applicable state law are excluded from consolidated billing. When a licensed psychologist provides psychological assessment, individual therapy, or group therapy to SNF residents, that psychologist may bill Medicare Part B directly rather than submitting charges to the facility for consolidation.

This exclusion is particularly relevant in SNFs with active mental health programming or behavioural health consultation arrangements. Facilities that have contracted with psychology groups for resident mental health services should confirm that the psychologist’s billing goes directly to Medicare Part B and is not being inadvertently consolidated into the SNF’s Part A claim.

Certain Dialysis Services

End-stage renal disease dialysis services provided to SNF residents are excluded from consolidated billing in certain circumstances specifically when the dialysis is furnished by a Medicare-certified ESRD facility. When a Part A SNF resident receives dialysis at an ESRD facility or when a certified dialysis provider furnishes dialysis services at the SNF, the dialysis provider may bill Medicare separately for those services. This exclusion does not apply to all kidney-related treatments only to ESRD dialysis services furnished by a certified ESRD provider. IV fluid administration, hydration therapy, and other kidney-related nursing interventions that the SNF nursing staff performs remain subject to consolidated billing.

Erythropoiesis-Stimulating Agents for ESRD

Erythropoiesis-stimulating agents administered in connection with renal dialysis services for ESRD are excluded from consolidated billing and may be billed separately by the ESRD dialysis provider. This exclusion is specific to the ESRD-dialysis context and does not extend to ESAs administered for other clinical indications, which remain subject to consolidated billing.

Certain Chemotherapy Drugs and Administration

Certain chemotherapy drugs and their administration are excluded from SNF consolidated billing. The specific drugs included in this exclusion are those that appear on the CMS list of separately billable drugs not all chemotherapy agents are excluded, and the exclusion applies to the drugs themselves and their direct administration rather than to all oncology-related services.

When a Part A SNF resident is receiving chemotherapy from an oncology provider, the SNF’s billing team should verify which specific agents are being administered and whether each fall within the excluded drug list before determining whether the oncology provider can bill Medicare separately or must submit charges to the SNF.

Certain Other High-Cost Drugs

Beyond chemotherapy, CMS maintains a list of other high-cost separately billable drugs that are excluded from consolidated billing. This list has historically included specific immunosuppressive drugs, certain injectable biologicals, and other drugs that CMS has determined are not appropriately bundled into the SNF per-diem payment. The specific drug list is updated periodically and should be verified against the current CMS Excluded Services from SNF PPS list not assumed to be the same as prior years.

What Is Not Excluded: The Services Most Commonly Billed in Error

The services most frequently billed to Medicare in error by outside providers during Part A SNF stays are not unusual or obscure services they are the common ancillary services that outside providers have billed directly to Medicare for non-SNF patients and mistakenly continue billing the same way when their patients are in a covered SNF stay.

Contract Therapy Services

Physical therapy, occupational therapy, and speech-language pathology services provided by contract therapy companies to Part A SNF residents are subject to consolidated billing. The therapy company submits its charges to the SNF. The SNF includes those charges in the consolidated Part A claim. Under PDPM, therapy services to Part A residents are bundled into the per-diem there is no separate Medicare payment for therapy minutes. A therapy company that attempts to bill Medicare Part B for services to a Part A resident is billing the wrong payer for a service that is already covered by the per-diem.

Laboratory Services

Laboratory tests ordered for Part A SNF residents are subject to consolidated billing. When the SNF sends a blood draw to an outside laboratory, the laboratory must submit its charges to the SNF not to Medicare. The SNF consolidates the laboratory charges into the Part A claim. Laboratories that routinely bill Medicare Part B directly for tests performed on SNF residents are creating consolidated billing conflicts that generate payment adjustments and may trigger audit activity.

Radiology Services

Portable X-ray services, other diagnostic imaging, and radiology services provided at the SNF to Part A residents are subject to consolidated billing. A radiology provider who performs a portable chest X-ray at the SNF must submit the charge to the facility for consolidation does not bill Medicare directly. This is one of the most violated consolidated billing rules because portable radiology providers frequently operate across both SNF and non-SNF patients and may not have workflows that separate the two correctly.

Respiratory Therapy

Respiratory therapy services provided by outside providers to Part A residents are subject to consolidated billing. When a contract respiratory therapist treats an SNF resident in a covered Part A stay, the therapy company’s charges go to the facility, not to Medicare directly.

What this means for your facility: The services not on the exclusions list are subject to consolidated billing regardless of how the outside provider has billed Medicare in the past. ‘We’ve always billed Medicare directly for our SNF patients’ is not a compliance defense. The obligation to consolidate applies to every non-excluded service, and the SNF is responsible for enforcing it with every outside vendor providing services to Part A residents.

Managing Consolidated Billing Compliance with Outside Vendors

The practical compliance challenge in consolidated billing is not knowing the rule it is ensuring that every outside provider delivering services to Part A residents understands and follows the rule for your specific facility’s patients. This requires active vendor management, not a one-time policy communication.

Every outside vendor arrangement that involves services to Part A residents should include a written confirmation of the vendor’s billing obligation specifically that the vendor will submit charges to the facility and not bill Medicare directly for services to covered Part A residents. This should be reviewed at the start of each contract relationship and confirmed when contract terms change.

Remittance review is the detection mechanism for consolidated billing violations that have already occurred. When an outside provider has billed Medicare directly for a service that should have been consolidated, the conflict typically surfaces as an adjustment on the SNF’s remittance Medicare reduces the consolidated claim because it has already paid the outside provider for the same service. Billing teams that review remittance adjustments at the line-item level, rather than at the total payment level, catch these patterns before they compound.
