# Build emergency readiness around the RNHCI care model > Use 42 CFR 403.748 - Emergency preparedness to review this narrow operational decision without extending the source beyond its stated scope. - Canonical URL: https://update.dsesecurity.com/updates/build-emergency-readiness-around-the-rnhci-care-model/ - Publisher: Detection Systems & Engineering (DSE Security) - Author: DSE Security Editorial Team - Published: 2026-08-27T12:12:10+00:00 - Modified: 2026-08-27T13:06:58+00:00 - Last reviewed by DSE: 2026-08-26 - Resource type: Briefing - DSE priority: Advisory - Topics: Business Continuity, Cybersecurity - Reading time: 3 minutes ## What you need to know Use 42 CFR 403.748 - Emergency preparedness to review this narrow operational decision without extending the source beyond its stated scope. ## Potentially affected Teams, systems, services, or facilities within the stated scope of 42 CFR 403.748 - Emergency preparedness ## DSE recommendation Compare the observed state with the cited official source, document applicability and exceptions, and test any approved change with rollback safeguards. ## Article Use this document to resolve one bounded operational decision: Build emergency readiness around the RNHCI care model. Only the official source and traced locations below supply facts. Confirm applicability before acting. ## Source fact: The official [42 CFR 403.748 – Emergency preparedness](https://www.ecfr.gov/current/title-42/section-403.748) from Centers for Medicare & Medicaid Services via eCFR supports the following bounded statements: - Under 42 CFR 403, the rule requires that the RNHCI develop and maintain an emergency preparedness training and testing program that is based on the emergency plan set forth in paragraph (a) of this section, risk assessment at paragraph (a)(1) of this section, policies and procedures at paragraph (b) of this section, and the communication plan at paragraph (c) of this section. The research record locates this support at 42 CFR 403.748(d) (eCFR anchor p-403.748(d)). - Under 42 CFR 403, the rule requires that if the emergency preparedness policies and procedures are significantly updated, the RNHCI conduct training on the updated policies and procedures. The research record locates this support at 42 CFR 403.748(d)(1)(v) (eCFR anchor p-403.748(d)(1)(v)). Only the traced statements above are asserted as source facts. Apply the review to essential functions, upstream providers, recovery sequences, alternate work paths, and tested recovery objectives after confirming that the source and deployed context match. ## What the source does not establish Provider-specific federal participation requirement; confirm current certification status, waivers, survey guidance, state law, and the complete section before applying it. A correct source interpretation can still be inapplicable to a particular design. Confirm identity, DNS, communications, facilities, suppliers, and the people authorized to invoke recovery, ownership, and change authority instead of treating documented behavior as a deployment guarantee. ## Applicability questions - For source statement 1 at 42 CFR 403.748(d) (eCFR anchor p-403.748(d)), which observable configuration, record, or test can confirm applicability here? - For source statement 2 at 42 CFR 403.748(d)(1)(v) (eCFR anchor p-403.748(d)(1)(v)), which observable configuration, record, or test can confirm applicability here? - Which deployed instance of essential functions, upstream providers, recovery sequences, alternate work paths, and tested recovery objectives will be compared with the source, and why that instance? - How will the review distinguish a source mismatch from a failure in identity, DNS, communications, facilities, suppliers, and the people authorized to invoke recovery? - Who approves the conclusion, exception, test window, and rollback threshold? ## DSE recommendation: DSE recommends using the cited source as the evidence anchor for this decision. Begin by recording scope and current state before deciding whether a change is warranted. Record the source location, examined part of essential functions, upstream providers, recovery sequences, alternate work paths, and tested recovery objectives, observed and expected states, owner, and reason for deviation. Do not move from citation to production in one step. Pilot the decision where practical, observe agreed signals, retain a reversal point, and verify identity, DNS, communications, facilities, suppliers, and the people authorized to invoke recovery. Handle credentials, keys, recovery data, and personal information through approved secure channels. ## Verification and evidence A reviewer should be able to retrace the decision from 42 CFR 403.748(d) (eCFR anchor p-403.748(d)); 42 CFR 403.748(d)(1)(v) (eCFR anchor p-403.748(d)(1)(v)) through business-impact records, dependency maps, exercise results, recovery timings, and open corrective actions. Record what was collected, where, when, by whom, and which system or role it represents. Preserve both successful and failed observations, along with approval and rollback evidence. Avoid uncontrolled production experiments. Assign an expiry or event-driven recheck so the conclusion is not treated as permanent. ## Official references - [42 CFR 403.748 – Emergency preparedness](https://www.ecfr.gov/current/title-42/section-403.748) — Centers for Medicare & Medicaid Services via eCFR ## Primary reference - Name: 42 CFR 403.748 - Emergency preparedness - Authority: www.ecfr.gov - URL: https://www.ecfr.gov/current/title-42/section-403.748 - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Build emergency readiness around the RNHCI care model,” DSE Security, https://update.dsesecurity.com/updates/build-emergency-readiness-around-the-rnhci-care-model/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
