State Licensure and CMS of an ASC

Regulatory Framework

ASC plumbing systems must comply with:

Federal Requirements

• CMS Conditions for Coverage

• 42 CFR §416 Ambulatory Surgical Centers

• CDC Infection Prevention Guidelines

• OSHA Bloodborne Pathogen Standards

Facility Safety Codes

• NFPA 99 – Health Care Facilities Code

• NFPA 101 – Life Safety Code

Arizona State Requirements

• Arizona Administrative Code Title 9 Chapter 10

• Arizona Department of Health Services (ADHS) facility licensing

Construction Codes

• International Plumbing Code (IPC)

• Local municipal building codes

Design Principles for ASC Plumbing

ng systems must support:

• Infection prevention• Surgical workflow separation• Reliable sterilization processes• Adequate water supply and pressure• Safe wastewater disposal

Design must ensure clean-to-dirty workflow separation in all areas.

Operating Room Scrub Sink Design

Scrub sinks must:

• Be located immediately outside each operating room• Provide minimum two scrub stations per operating room• Allow full forearm washing• Include hands-free operation• Have deep basins to reduce splashing• Include laminar flow faucets

Scrub sinks must be separate from handwashing sinks used for routine hygiene.

Hand Hygiene Sink Requirements

Handwashing sinks must be conveniently located in:

• Pre-operative holding areas

• Post anesthesia care units (PACU)

• Sterile processing clean side

• Medication preparation areas

• Clean utility rooms

• Soiled utility rooms

• Clinical treatment areas

Design features must include:

• Hands-free operation• Gooseneck faucet• Splash protection• Hot/cold mixing valve

Maximum water temperature: 110°F

Sterile Processing Plumbing

Instrument reprocessing areas must contain:

Decontamination Area

Required equipment:

• Three-compartment sink• Large basins capable of holding instrument trays• Indirect drainage system• Backflow prevention

Workflow must proceed:

Soiled → Decontamination → Clean Assembly → Sterilization → Storage

Cross-contamination pathways must be prevented.

Utility Room Requirements

Soiled Utility Room

Must include:

• Clinical service sink• Waste disposal area• Handwashing sink• Splash protection

Clean Utility Room

Must include:

• Handwashing sink• Clean storage space

These areas must be physically separated.

Backflow Prevention

Healthcare facilities must protect municipal water systems from contamination.

Required protections include:

• Backflow prevention valves• Vacuum breakers on hose bibs• Cross-connection control systems

Backflow devices must be:

• Installed by certified technicians• Tested annually

Water Heating Systems

Hot water systems must provide:

• Adequate supply during surgical peak hours• Anti-scald protection• Thermostatic mixing valves

Water temperature must not exceed 110°F at handwashing stations.

Medical Gas Systems

Medical gas piping systems must comply with NFPA 99.

Typical systems include:

• Oxygen• Medical air• Vacuum suction• Nitrous oxide (if used)

Systems must undergo:

• Pressure testing• Leak testing• Certification documentation

Plumbing Design Considerations

ASC construction drawings must include:

• Plumbing riser diagrams• Fixture schedules• Medical gas diagrams• Water heater capacity calculations• Backflow prevention systems

Plans must be approved before construction begins.

2. ASC Plumbing Fixture Schedule Template

Architects typically use a fixture schedule table similar to this.
