Key takeaways
- Name the rule behind the label; there is no single nationwide ownership test.
- Corporate-stock treatment under one Medicare provision does not settle other requirements.
- A contract signature or application receipt is not operating authority.
Identify the rule and the legal provider
Section 489.18 sets out Medicare rules for changes involving partners, sole owners, corporations and leases. It addresses what happens to the provider agreement. A state license or another payer's contract may use a different test. (42 CFR 489.18)
Washington's adult-family-home rule separately addresses changes in the provider or its control and requires a new application and license for covered changes. Its exceptional provisional-license pathway requires actual approval. Do not apply this state's rule to a different setting or jurisdiction. (WAC 388-76-10105)
A fictional corporate-share example
Suppose a buyer proposes to acquire all shares of a provider corporation operating a home-health agency. Its initial Medicare enrollment was eighteen months earlier, and assume no exception applies. The corporate-stock clause in 489.18 does not classify that stock transfer as a CHOW under that clause.
A stock sale still needs another test. For home-health agencies and hospices, 424.550 can require a new enrollment for a sale within the specified thirty-six-month period, unless an exception applies. Stock transfers are among the covered forms of sale. Check the real ownership history and any claimed exception before assuming that the agreement and billing rights will pass. (42 CFR 424.550)
CMS's May 13, 2026 initial six-month moratorium also covers non-exempt CIMO initial applications. Waiting, restructuring or filing does not establish an available path without current review. (CMS moratorium)
Why it matters in a senior care sale
Keep the classification, required filings and actual decisions separate in the closing record. A change in ownership facts can reopen the review. Federal text was checked September 6, 2026; rules and program status need confirmation for the actual transaction.
The adult-day transfer exercise examines a fictional California ADHC and CBAS packet. It uses a different program context from the federal example here. The records cover program review, receipt, a date field and a contract request. The shared CHOW label does not merge those decisions or give permission to operate.
The Medicare-CHOW guide explains the wider process. The complete buying guide shows how an unresolved authority question affects a fictional budget and closing plan.
The Medicare certification definition and CMS-855A definition help separate a status decision from an application. Read those records alongside the transaction structure; neither document name answers every transfer question.
Frequently asked questions
Is CHOW just another name for selling the building?
No. An ownership review concerns the provider or operation under the applicable rule. Real estate may be involved, but a property deed alone does not describe every change in the service business. Map the entities, control, assets and leases before classifying the transaction.
Does buying all corporate shares always count as a Medicare CHOW?
The specific corporate provision in 42 CFR 489.18 says a corporate stock transfer is not a CHOW under that provision. Separate ownership, enrollment and state requirements may still apply. That narrow statement is not a safe harbor for the entire acquisition.
Does a CHOW application let the buyer begin operating?
Do not assume so. Submission and permission are different events, and the governing rule determines the required sequence. Obtain advice and actual evidence for the proposed transaction. Washington adult-family-home rules, for example, require the applicable license before operation, with a specifically granted provisional-license exception.
What records help resolve the classification?
Use current and proposed ownership charts, entity records, transaction documents, provider identifiers, enrollment history and the actual licenses or contracts. Counsel and the responsible authorities need the real facts. A seller’s summary or the initials CHOW cannot settle the result alone.
