Prescriptive and non-prescriptive standards: what home health and hospice agencies should understand when comparing accreditation requirements.
When selecting ACHC or CHAP, agencies often focus on price, survey timing, and preparation resources. Another useful question is how clearly the standards define required actions and how much discretion an agency has in demonstrating compliance.
CHAP explicitly describes its standards as non-prescriptive. ACHC also publishes detailed requirements and evidence expectations. However, these descriptions should not be treated as a universal rule that ACHC permits only one method while CHAP permits any method that achieves a desired result. The actual flexibility depends on the individual standard, its interpretation, and applicable law.

What Does Prescriptive Mean?
A prescriptive requirement specifies particular actions, elements, documentation, or processes that must be in place. It may require a written policy, identify information a record must contain, or establish a deadline or assigned responsibility.
Such detail can help an agency understand exactly what it needs to establish before survey. It can also make it easier to assign responsibilities and check whether required documentation is complete.
If a regulation or accreditation standard expressly requires a particular element, an alternative process that achieves a similar goal may still be insufficient. The agency must satisfy the actual requirement or obtain clarification through the appropriate authority.
What Does Non-Prescriptive Mean?
A non-prescriptive approach allows discretion in how an organization meets a requirement when the requirement does not mandate one specific method. The agency still needs to show that its chosen process fulfills the standard.
CHAP describes this philosophy as supporting flexibility and innovation. For an agency, that means developing processes appropriate to its size, structure, services, and patient population while meeting all applicable requirements.
For example, a hypothetical oversight standard might permit several ways to demonstrate that leaders review operational performance. Meeting records, documented evaluations, or reports may be useful evidence, depending on the actual standard. This example is not a determination that any particular document will satisfy either accreditor.
Non-prescriptive does not mean optional. A requirement to complete an assessment, maintain a record, or act within a specified timeframe remains mandatory when the governing regulation or standard requires it.
How Should Agencies Compare ACHC and CHAP?
ACHC’s home health preparation guidance directs agencies to review the standards, understand their intent, and seek interpretation when a requirement’s application to the business model is unclear. Detailed evidence expectations can make some requirements feel more directive during policy development.
CHAP’s non-prescriptive philosophy can be helpful when an agency wants to understand where its established systems may meet a standard without adopting a single preferred workflow. Agencies should still read the full standard and supporting evidence guidance.
The useful comparison is therefore at the level of an individual requirement. Ask what is mandatory, what evidence is expected, and which implementation choices remain open. A detailed standard may leave discretion in some areas; a non-prescriptive framework can still contain explicit obligations.
How Does This Affect Survey Preparation?
For either accreditor, start by separating three questions:
- What must be done? Identify the required action, responsible role, timing, and any specified documentation.
- How will the agency do it? Define a workable process that fits the agency and satisfies every required element.
- How will the agency demonstrate it? Identify records, staff knowledge, observations, and other evidence showing that the process is consistently followed.
When a standard names specific elements, check each one. When it allows discretion, be prepared to explain how the chosen process meets the requirement and show evidence that it works.
In both cases, a policy manual alone is insufficient. Staff must understand their responsibilities, required activities must occur, and records must accurately reflect actual operations.
Does Non-Prescriptive Mean CHAP Is Easier?
It does not establish that the survey will be easier or produce fewer deficiencies. Flexibility in implementation does not reduce the agency’s obligation to comply.
Home health Conditions of Participation are in 42 CFR Part 484. Hospice Conditions of Participation are in 42 CFR Part 418. The applicable federal requirements remain in force regardless of which CMS-approved accrediting organization performs the survey.
Each accreditor also maintains its own program standards. Agencies must understand the current requirements for their selected program, including any requirements beyond the federal minimum.
Flexibility in how compliance is demonstrated should not be confused with flexibility in whether compliance is required.
Which Approach Fits Your Agency?
Leadership teams that prefer detailed guidance should examine how each organization sets out its requirements and evidence expectations. Teams with established systems should ask how those systems will be evaluated and whether changes are necessary.
Compare current editions of the standards rather than choosing solely on the labels prescriptive or non-prescriptive. Useful questions include:
- Does the standard require a specific document, process, or timeframe?
- Which elements come directly from federal or state law?
- Where may the agency choose its own implementation method?
- What evidence will be used to evaluate compliance?
- How can the agency obtain a program-specific interpretation before survey?
Also consider educational resources, survey processes, accreditation costs, and ongoing support. One feature of the standards should not determine the entire decision.
What About Non-Medical Home Care?
Both organizations offer home care accreditation programs separate from Medicare-deemed home health and hospice accreditation. Compare the standards for the actual service line being pursued; do not assume a description of a hospice, home health, or other accreditation program applies unchanged to non-medical home care.
Confirm the program’s suitability and recognition with the relevant state authority, payer, and accrediting organization.
Read the Requirement, Then Build the Evidence
The distinction between detailed instructions and implementation flexibility is useful because it changes the questions an agency should ask during preparation. It does not replace a careful reading of the standards.
Regardless of accreditor, successful preparation requires knowledgeable leadership, clear responsibilities, effective operational systems, and evidence that required activities are consistently performed.
Choose an accreditation program after understanding both its mandatory requirements and the decisions your agency is allowed to make for itself.
