## What Is Workers’ Compensation Insurance?

Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. [9](https://content.naic.org/insurance-topics/workers%27-compensation-insurance "Workers’ Compensation Insurance") [10](https://content.naic.org/consumer/small-business.htm "Small Business Insurance") [11](https://www.dir.ca.gov/dwc/Employer.htm "DWC employer information") [12](https://www.tdi.texas.gov/wc/employer/index.html "Employer resources")

## Key Differences in Workers’ Compensation Insurance

### Claims and Return-to-Work Services

CNA says it provides safety information, training, and risk-control programs to help businesses build return-to-work strategies, and its dedicated workers’ compensation claims team averages 20 years of experience. biBerk says its team guides policyholders through a reported claim, without describing a dedicated safety or return-to-work service in the reviewed record. Ask CNA which services are available to your operation and biBerk how its claim guidance is delivered. [8](https://www.cna.com/products/workers-compensation "Workers’ Compensation Insurance | CNA Insurance") [3](https://www.biberk.com/small-business-insurance/workers-compensation-insurance "Workers’ Compensation Insurance From biBerk | Get A Quote")

### Benefits and Payroll

Both describe medical care and wage-related benefits for work injuries. biBerk also explains that premiums use gross annual payroll and that an audit compares estimates with actual payroll during the policy period; CNA’s cited overview focuses on coverage and claims resources rather than premium calculation. Bring payroll by job category to either quote. [8](https://www.cna.com/products/workers-compensation "Workers’ Compensation Insurance | CNA Insurance") [3](https://www.biberk.com/small-business-insurance/workers-compensation-insurance "Workers’ Compensation Insurance From biBerk | Get A Quote")

A cited review says biBerk is unavailable in four state-run-fund jurisdictions; CNA’s reviewed claims do not specify a state footprint. [4](https://www.nerdwallet.com/business/insurance/learn/biberk-insurance "biBerk Insurance Review 2026: Berkshire Hathaway’s Basic Online Storefront | NerdWallet") [8](https://www.cna.com/products/workers-compensation "Workers’ Compensation Insurance | CNA Insurance")

## What to Confirm in Workers’ Compensation Insurance Quotes

- Ask CNA what return-to-work support and claims contact timing apply to your account. [8](https://www.cna.com/products/workers-compensation "Workers’ Compensation Insurance | CNA Insurance")
- Ask biBerk about state availability and how payroll audits affect final premium. [3](https://www.biberk.com/small-business-insurance/workers-compensation-insurance "Workers’ Compensation Insurance From biBerk | Get A Quote")
