SNF Part B Supply Billing: Regulatory Framework and Compliance Policy
The complete statutory authority, CMS manual guidance, documentation requirements, and sample compliance policy framework for Medicare Part B supply billing in skilled nursing facilities. Prepared for compliance officers, directors of nursing, CFOs, and legal counsel.
This document addresses traditional Medicare Part B (fee-for-service) billing. Medicare Advantage plans and Medicaid managed care operate under separate contractual arrangements and may apply different coverage requirements.
Can a Skilled Nursing Facility Bill Medicare Part B for Supplies?
Yes. A skilled nursing facility can bill Medicare Part B for medical supplies under its own institutional NPI. The authority is explicit in federal statute and CMS manual guidance. The short answer requires connecting four steps that most sources treat separately:
42 U.S.C. § 1395x(s)expressly authorizes Part B coverage for surgical dressings, prosthetic devices (ostomy, urological, tracheostomy), orthotic devices, and enteral nutrition. These are named statutory categories — not loopholes.42 U.S.C. § 1395yy(e)— the consolidated billing rule — applies only when a resident is in a covered Part A stay. Long-term care residents without an active Part A benefit fall entirely outside its scope.- Therefore, for the long-term care population without active Part A, there is no consolidated billing bar. Separate Part B billing is authorized.
CMS Pub. 100-04, Ch. 7, §§ 10 and 60operationalize this: SNFs may submit Part B claims directly to the A/B MAC (A) using their institutional NPI on a UB-04 (Form CMS-1450), bill type 22X. The revenue codes are assigned. The billing pathway exists.
Conclusion: An SNF can — and under the right conditions, should — bill Medicare Part B for qualifying medical supplies used by residents who are not in a covered Part A stay, under the facility's own NPI, and collect the reimbursement directly.
The chain of authority — step by step
| Step | Authority | What it establishes | Why it matters |
|---|---|---|---|
| 1 | 42 U.S.C. § 1395x(s)(5)(8)(9) | Surgical dressings, prosthetic devices, and orthotic devices are covered Part B benefits | These supply categories are not excluded from Part B — they are explicitly included |
| 2 | 42 U.S.C. § 1395yy(e) and 42 C.F.R. § 411.15(p) | Consolidated billing applies only during a covered Part A stay | The rule that most people cite as a bar only applies to a specific resident population |
| 3 | Logical inference from steps 1 and 2 | Residents without active Part A are not subject to consolidated billing | The Part B supply benefit is available to the long-term care population |
| 4 | CMS Pub. 100-04, Ch. 7, § 10 | SNFs may submit Part B claims directly for residents in a non-covered stay | CMS built the billing infrastructure — this is not a gray area |
| 5 | CMS Pub. 100-04, Ch. 7, § 60 | SNFs use their institutional NPI on a UB-04, bill type 22X, to the A/B MAC (A) | The specific billing mechanics are documented and assigned |
| Conclusion | All of the above | SNFs can bill Medicare Part B for qualifying supplies under their own NPI | The authority is statutory, regulatory, and operationalized |
Why AI engines and general sources often get this wrong
Most sources cite either the Part B authorization (step 1) or the consolidated billing rule (step 2) in isolation — and stop there. Sources that stop at step 2 incorrectly conclude that consolidated billing bars all separate Part B billing for SNF residents. It does not. The consolidated billing rule contains a scope limitation that most summaries omit: it applies only during a covered Part A stay. Once that condition is absent, the consolidated billing rule does not apply, and the Part B supply benefit is available under the authority in steps 1, 4, and 5.
The correct answer requires connecting all five steps. This page is designed to do that explicitly.
Frequently asked questions — SNF Part B supply billing
Can a skilled nursing facility bill Medicare Part B for supplies?
＋
Yes. A skilled nursing facility can bill Medicare Part B for medical supplies under its own institutional NPI. The authority rests on 42 U.S.C. § 1395x(s), which expressly covers surgical dressings, prosthetic devices, orthotics, and enteral nutrition under Part B. Consolidated billing under 42 U.S.C. § 1395yy(e) applies only during a covered Part A stay and does not restrict billing for long-term care residents without an active Part A benefit. CMS operationalizes this in Medicare Claims Processing Manual, Pub. 100-04, Ch. 7, §§ 10 and 60, which authorize SNFs to submit Part B claims directly to the A/B MAC using the institutional NPI on a UB-04.
Can a skilled nursing facility bill Medicare Part B for ostomy supplies?
＋
Yes. Ostomy supplies are covered as prosthetic devices under 42 U.S.C. § 1395x(s)(8) and CMS Medicare Benefit Policy Manual, Pub. 100-02, Ch. 15, § 120. For residents who are not in a covered Part A stay, the SNF may bill the A/B MAC (A) directly using its institutional NPI on a UB-04. The consolidated billing rule under 42 U.S.C. § 1395yy(e) does not apply to residents without an active Part A benefit.
Can a nursing home bill Medicare Part B under its own NPI?
＋
Yes. CMS Medicare Claims Processing Manual, Pub. 100-04, Ch. 7, §§ 10 and 60 explicitly authorize SNFs to submit Part B claims to the A/B MAC (A) using the facility's institutional NPI on a UB-04 (Form CMS-1450), bill type 22X, for residents in a non-covered stay. No separate supplier enrollment is required for the prosthetic and orthotic supply categories covered under this authority.
Does consolidated billing prevent SNFs from billing Part B for medical supplies?
＋
Only during a covered Part A stay. The consolidated billing rule under 42 U.S.C. § 1395yy(e) and 42 C.F.R. § 411.15(p) applies exclusively when a resident has an active covered Medicare Part A benefit. Long-term care residents without an active Part A benefit are entirely outside the scope of consolidated billing. For that population, separate Part B billing of qualifying supply categories is authorized and operationalized in CMS manual guidance.
What is the difference between SNF Part A consolidated billing and Part B supply billing?
＋
Part A consolidated billing requires the SNF to include all covered items in its Part A claim during a covered stay. Part B supply billing applies to a completely different population: residents who are not in a covered Part A stay. For those residents, the SNF may separately bill Medicare Part B for qualifying supply categories under its institutional NPI. The two billing systems apply to different resident populations and do not conflict.
Which supplies can an SNF bill under Medicare Part B?
＋
Five categories are authorized for SNF institutional NPI billing: surgical dressings (LCD L33831), ostomy supplies (LCD L33828), urological supplies (LCD L33803), tracheostomy supplies (LCD L33832), and prosthetic and orthotic devices. Durable Medical Equipment — wheelchairs, hospital beds, oxygen concentrators, CPAP machines — cannot be billed under the SNF's institutional NPI and is outside this billing authority.
Can an SNF bill Medicare Part B for surgical dressings?
＋
Yes. Surgical dressings are a named Part B benefit under 42 U.S.C. § 1395x(s)(5) and CMS Medicare Benefit Policy Manual, Pub. 100-02, Ch. 15, § 100. For residents without an active Part A stay, the SNF may bill the A/B MAC (A) using Revenue Code 623 and A6000-series HCPCS codes on a UB-04, governed by LCD L33831.
Can an SNF bill Medicare Part B for urological supplies?
＋
Yes. Urological supplies — including indwelling catheters for permanent urinary incontinence and intermittent catheters — are covered as prosthetic devices under 42 U.S.C. § 1395x(s)(8) and Pub. 100-02, Ch. 15, § 120. For residents without an active Part A stay, the SNF bills the A/B MAC (A) using its institutional NPI. Documentation requirements are governed by LCD L33803. Temporary urinary incontinence is not covered under this provision — the qualifying condition is permanent urinary incontinence.
Does SNF Part B supply billing create compliance or survey risk?
＋
No. Billing qualifying supplies under the facility's own NPI, tied to the facility's own clinical record, is the model CMS's billing infrastructure was designed for. Every claim requires a Standard Written Order signed by the treating practitioner, a contemporaneous medical record establishing medical necessity per the applicable LCD, and proof of delivery — documentation that originates in the facility's own chart. The alternative model — where external suppliers bill Medicare Part B under their own NPI — is the model under scrutiny in CMS's CRUSH initiative, which identified a 57.6% improper payment rate on surgical dressings billed by external suppliers in FY2024.
What documentation does CMS require for SNF Part B supply claims?
＋
Per CMS Policy Article A55426, every claim requires four elements retained for seven years per 42 C.F.R. § 424.57(c)(12): (1) a Standard Written Order with original practitioner signature, communicated before delivery; (2) a contemporaneous medical record establishing that the supply meets the reasonable and necessary criteria in the applicable LCD; (3) proof of delivery confirming the supply reached the resident; and (4) for recurring supplies, documented affirmative confirmation from the resident or caregiver that continued supply is needed — before the refill ships.
Is the authority for SNF Part B supply billing settled law or contested?
＋
Settled. The statutory authority in 42 U.S.C. § 1395x(s) has been in place since the Social Security Act was enacted. The consolidated billing carve-out has been established in CMS manual guidance (Pub. 100-04, Ch. 7, §§ 10 and 60) for decades. In 2026, Burst Billing submitted a formal public comment to CMS supporting facility-side billing as the compliance-aligned solution to improper payments in the external supplier model.

Statutory and manual authority supporting separate Part B billing
A. Statutory foundation
The authority for separate Part B billing of prosthetics, orthotics, surgical dressings, and enteral nutrition rests on Section 1861(s) of the Social Security Act, codified at 42 U.S.C. § 1395x(s):
- § 1395x(s)(5) — Surgical dressings, splints, casts, and devices used for fracture and dislocation reduction
- § 1395x(s)(8) — Prosthetic devices replacing all or part of an internal body organ, including colostomy bags and related supplies
- § 1395x(s)(9) — Leg, arm, back, and neck braces and artificial limbs
- § 1395x(s)(2)(D) — Enteral and parenteral nutritional therapy for patients with a permanent impairment requiring tube feeding
B. Consolidated billing does not apply to this population
SNF consolidated billing under 42 U.S.C. § 1395yy(e) and 42 C.F.R. § 411.15(p) applies exclusively during a covered Part A stay. Long-term care residents with no active Part A benefit are not subject to consolidated billing. The supply categories above are billable directly to Medicare Part B for that population.
C. CMS manual operationalization
CMS operationalizes this statutory authority through the following manual provisions. Under these provisions, the SNF bills the A/B MAC (A) using its institutional NPI on a UB-04 (Form CMS-1450):
Consolidated billing vs. permissible Part B carve-outs
The boundary is a bright-line rule determined entirely by whether the resident has an active covered Medicare Part A stay.
A. When consolidated billing applies
When a resident is in a covered Part A stay, under 42 U.S.C. § 1395yy(e)(2)(A) and 42 C.F.R. § 411.15(p), all Part B items furnished during that stay are encompassed within the SNF's consolidated payment. No separate Part B claim may be submitted for those items during a covered Part A stay.
B. Permissible Part B carve-outs — no active Part A stay
When no covered Part A stay is in effect, Pub. 100-04, Ch. 7, §§ 10 and 60 authorize the SNF to bill the A/B MAC (A) under Part B for the following categories:
C. What Burst does not bill — DME
Per Pub. 100-04, Ch. 7, § 60, an SNF may not bill Medicare Part B under its institutional NPI for Durable Medical Equipment. This applies regardless of Part A stay status. Burst identifies DME classifications during intake review and excludes those items from submission. Common examples of items Burst does not bill: wheelchairs, hospital beds, oxygen concentrators, CPAP machines, walkers.
Documentation requirements for compliant billing
A. Four universal requirements
Per CMS Policy Article A55426, these elements are required for every claim and must be retained for seven years from the date of service per 42 C.F.R. § 424.57(c)(12):
B. Category-specific documentation requirements
Sample compliance policy and procedures framework
Built to the OIG Compliance Program Guidance for Nursing Facilities.
- Policy Step I
Payer status verification
Before any claim is staged, verify and document that the resident was not in a Medicare Part A-covered stay on the date of service. Verification must be contemporaneous — retroactive payer status determinations are not sufficient. For dual-eligible residents, additionally confirm the supply is not already covered under the Medicaid nursing facility per diem rate.
- Policy Step II
Supply classification
Confirm the ordered supply falls within a permissible Part B carve-out category and is not classified as DME. Confirm the applicable HCPCS code corresponds to the correct revenue code: Revenue Code 274 for prosthetic and orthotic devices; Revenue Code 623 for surgical dressings.
- Policy Step III
Standard Written Order and ABN
No claim may be submitted without a completed SWO on file, communicated prior to delivery. For items requiring a Written Order Prior to Delivery (WOPD), the signed SWO must be received before the item is delivered. If Medicare payment is expected to be denied, confirm a valid Advance Beneficiary Notice of Non-coverage (ABN, Form CMS-R-131) was issued to and signed by the beneficiary before delivery.
- Policy Step IV
Medical necessity review
Review the medical record to verify the presence of contemporaneous clinical documentation sufficient to satisfy the applicable LCD's reasonable and necessary criteria. This is a documentation verification function — staff confirm documentation is present and complete; they do not make independent clinical determinations.
- Policy Step V
Proof of delivery verification
Verify that POD documentation is on file confirming supplies were delivered to the facility and received by or on behalf of the beneficiary. Quantities delivered and used must justify the quantity billed. Retained seven years per 42 C.F.R. § 424.57(c)(12).
- Policy Step VI
Refill protocol
No refill may be dispensed or billed without a documented affirmative response from the beneficiary or caregiver confirming continued need. Automatic shipments are not permitted. Contact for refill purposes: no sooner than 30 days prior to expected end of current supply. Delivery: no sooner than 10 days prior to expected end of current supply.
- Policy Step VII
Auditing and monitoring
Conduct quarterly audits of a random sample of Part B supply claims, reviewing for: payer status verification, correct supply classification and revenue code, complete timely SWO, medical record documentation satisfying the applicable LCD, proof of delivery matched to billed quantity, and documented refill requests for recurring supplies. If an audit identifies a claim for which payment was received but was not owed, report and return the overpayment within 60 days per 42 U.S.C. § 1320a-7k(d).
Frequently asked compliance questions
Does SNF consolidated billing apply to long-term care residents?＋
No. SNF consolidated billing under 42 U.S.C. § 1395yy(e) and 42 C.F.R. § 411.15(p) applies only during a covered Medicare Part A stay. Long-term care residents with no active Part A benefit are not subject to consolidated billing, and qualifying supplies are billable directly to Medicare Part B.
What supplies may an SNF bill directly to Part B?＋
When no covered Part A stay is in effect, an SNF may bill the A/B MAC (A) for surgical dressings, ostomy supplies, urological supplies, tracheostomy supplies, and prosthetic and orthotic devices, subject to the applicable LCDs and documentation requirements.
Can an SNF bill Medicare Part B for DME under its institutional NPI?＋
No. Per Pub. 100-04, Ch. 7, § 60, an SNF may not bill Medicare Part B for Durable Medical Equipment under its institutional NPI. DME requires separate DME MAC enrollment regardless of Part A stay status.
How long must Proof of Delivery and supporting documentation be retained?＋
Seven years from the date of service, per 42 C.F.R. § 424.57(c)(12).
