Class Code 9043
Hospitals
Class Code 9043 applies to hospitals and the broad range of clinical and support staff who provide inpatient, emergency, surgical and diagnostic services. The WCIRB-approved pure premium rate for California effective September 1, 2026 is $1.910 per $100 of payroll. Understanding this classification helps hospital administrators manage payroll reporting, safety programs and workers' comp cost drivers specific to healthcare.
What Class Code 9043 Covers
This classification covers general acute-care hospital operations and the employees working in clinical units (medical/surgical, ICU, ER), operating rooms, diagnostic departments (radiology, laboratory), ancillary clinical services (respiratory therapy, pharmacy), and many on-premises support functions directly employed by the hospital. It includes both direct patient-care activities and the routine support necessary to operate a licensed hospital — patient transport, environmental services, dietary services, central sterile processing, and in-house maintenance when employed by the hospital. Outpatient clinics owned and operated by the hospital are typically included when staff are on the hospital payroll. Independent contractors, physicians with independent practice agreements, and certain third-party service providers may be classified separately depending on contract and payroll arrangements.

- Hospital-employed RNs, LPNs and nursing assistants (CNAs)
- Emergency department, surgical and perioperative teams (surgical techs, O.R. nurses)
- Clinical lab, imaging and respiratory therapy staff
- Hospital-employed environmental services, dietary and facilities/maintenance workers
- Hospital-employed security and patient transport personnel

Common Injury Risks
Understanding the $1.910 Rate
The WCIRB pure premium of $1.910 per $100 of payroll represents the expected loss cost (medical + indemnity) for losses in this classification; insurers use it as the base to calculate premiums. Final employer premiums will be higher or lower depending on carrier loss cost multipliers, your hospital's experience modification (E-Mod), premium discounts, policy protections (deductibles or retrospective rating) and the specific payroll mix of job classes reported.
Cal/OSHA Compliance Requirements
Hospitals must comply with Cal/OSHA requirements including the Injury and Illness Prevention Program (IIPP, Title 8 §3203), Bloodborne Pathogens (Title 8 §5193) and the Aerosol Transmissible Diseases standard (Title 8 §5199), plus Respiratory Protection (§5144) and Hazard Communication (§5194). Cal/OSHA also expects effective workplace violence prevention, safe patient handling programs and written exposure control plans; hospitals should maintain fit testing, vaccination and post-exposure protocols specific to healthcare operations.
How Key HR Helps Employers Under Class Code 9043
A PEO like Key HR helps hospitals manage workers' comp exposure through centralized claims management, clinical nurse triage, return-to-work coordination and employer-focused loss-prevention programs (safe patient handling, violence prevention, infection control training). Key HR also aggregates payroll and risk data to negotiate better pricing, monitor experience modification trends, and implement targeted safety interventions that reduce frequency and severity of claims.
Get a QuoteFrequently Asked Questions
Are all hospital employees automatically classified under 9043?
Not necessarily. Employees on the hospital payroll who perform clinical and most onsite support duties are typically under 9043, but some groups (clerical staff, physicians with independent practices, certain contracted services) can be assigned other class codes. Proper payroll coding requires reviewing job duties and contract arrangements.
What are the most effective ways hospitals can lower workers' comp costs for this class?
Invest in safe patient handling and lifting equipment, comprehensive bloodborne pathogen and infection control programs, workplace violence prevention, early return-to-work/transitional duty policies, and focused training for ER and psychiatric units. Active claims management and timely incident investigation also reduce long-term costs.
Does the $1.910 pure premium equal my insurance bill?
No. The pure premium is the loss-cost basis per $100 of payroll. Actual premiums include insurer multipliers, state assessments, your hospital's E-Mod or credit, policy features (deductibles or retrospective plans), and the payroll mix of different job classes.
