CMS (Centers for Medicare & Medicaid Services)
The Centers for Medicare & Medicaid Services (CMS) is the federal agency within the Department of Health and Human Services that administers Medicare, Medicaid, and the Children's Health Insurance Program. For home health agencies, CMS sets the Conditions of Participation, payment policy under the Home Health Prospective Payment System, OASIS and quality reporting requirements, and program integrity rules. Nearly every operational requirement in a Medicare-certified agency traces back to CMS.
What CMS controls in home health
CMS defines both sides of the home health business: how agencies must operate and how they get paid. On the operations side, CMS writes the Conditions of Participation at 42 CFR Part 484 and oversees the survey process that enforces them. On the payment side, CMS runs the Home Health Prospective Payment System, which since January 2020 uses the Patient-Driven Groupings Model (PDGM) with 30-day payment periods. CMS also owns the OASIS data set and the iQIES submission system, the expanded Home Health Value-Based Purchasing (HHVBP) model, public reporting on Care Compare, and medical review programs such as Targeted Probe and Educate (TPE) and the Review Choice Demonstration (RCD).
How CMS policy reaches your agency
CMS policy flows through several channels. Each year CMS publishes a proposed Home Health PPS rule, usually in early summer, and a final rule in the fall that sets the next calendar year's payment rates, case-mix weights, and LUPA thresholds. Standing policy lives in the manuals, especially the Medicare Benefit Policy Manual, Chapter 7, for coverage rules and the Medicare Claims Processing Manual, Chapter 10, for billing. Day-to-day claim decisions come from Medicare Administrative Contractors (MACs), the private contractors CMS pays to process claims and conduct medical review. Survey enforcement runs through state survey agencies and CMS-approved accrediting organizations.
CMS programs every home health operator should track
A handful of CMS programs drive most of an agency's regulatory and financial exposure:
- The annual Home Health PPS rule: the CY2026 final rule cut aggregate payments an estimated 1.3 percent versus CY2025
- Expanded HHVBP, which adjusts Medicare fee-for-service payments up or down by as much as 5 percent based on quality performance
- OASIS-based quality reporting, submitted through iQIES
- Care Compare star ratings, which referral sources and payers see
- Medical review programs, including TPE and RCD in participating states
Assign an owner for each so rule changes get translated into workflow changes.
Working with CMS in practice
Most agencies never interact with CMS headquarters directly. Enrollment and revalidation run through PECOS, claims and appeals run through the MAC, and survey issues run through the state agency or accreditor. Where agencies can influence CMS is the annual rulemaking cycle: proposed rules carry a 60-day comment period, and industry comments have shaped final policies, including phase-ins of payment adjustments. Operationally, put the proposed rule (summer) and final rule (fall) on the calendar every year, and reconcile your fee schedules, LUPA thresholds, and case-mix weights against the final rule before January 1.
Frequently asked questions
Does CMS survey home health agencies itself?
Rarely. CMS delegates routine surveys to state survey agencies and to accrediting organizations with deeming authority (ACHC, CHAP, and The Joint Commission). CMS retains authority over enforcement decisions, such as termination and alternative sanctions, and can conduct validation reviews.
What is the difference between CMS and my MAC?
CMS writes the rules; the Medicare Administrative Contractor operationalizes them. MACs process claims, pay or deny them, run medical review, and answer provider inquiries for their jurisdiction. When you appeal a denial or submit a Notice of Admission, you are working with your MAC, not CMS directly.
How does CMS update home health payment rates?
Through annual notice-and-comment rulemaking. The Home Health PPS proposed rule comes out around June or July, and the final rule lands around late October or November with rates effective January 1. The rule also updates case-mix weights, LUPA thresholds, wage indexes, and quality program requirements.
