Excavation NOC Workers Compensation (class code: 6218, 6220) Insurance

What is Excavation NOC Workers Compensation (class code: 6218, 6220)?

Excavation NOC (Not Otherwise Classified) Workers Compensation insurance is designed to protect businesses involved in excavation work, such as trenching, grading, and foundation digging. Class codes 6218 and 6220 are used to classify excavation operations that don't fall under more specific codes. This insurance provides medical and wage benefits to employees who are injured on the job and helps employers meet legal obligations in most states.

Who needs it

Any business involved in excavation activities—including site preparation, land clearing, or underground utility installation—should carry workers compensation insurance. This includes general contractors, subcontractors, and independent excavation companies. If your employees use heavy equipment like backhoes or bulldozers, or work in trenches and uneven terrain, this coverage is essential.

What it typically covers

Workers compensation insurance for excavation operations generally includes:

  • Medical expenses for work-related injuries or illnesses
  • Lost wages during recovery periods
  • Rehabilitation and physical therapy
  • Disability benefits (temporary or permanent)
  • Death benefits for surviving dependents

This coverage helps protect both employees and employers from the financial impact of workplace accidents.

Common exclusions/limitations

While workers comp covers most job-related injuries, exclusions may include:

  • Injuries occurring while under the influence of drugs or alcohol
  • Self-inflicted injuries or intentional misconduct
  • Injuries that happen off-duty or off-site
  • Independent contractors not classified as employees

Policy terms and exclusions can vary, so it's important to review your coverage with a licensed agent.

Factors that influence cost

Several factors impact the cost of workers compensation for excavation businesses:

  • Type of excavation work performed and associated risks
  • Number of employees and total payroll
  • Past claims history and safety record
  • State-specific rates and classification codes

Rates are often higher for excavation due to the physical hazards involved, but maintaining a strong safety program can help reduce premiums.

Proof of insurance & compliance

Most states require excavation companies to carry valid workers compensation insurance and provide proof before starting work, especially on construction sites. Certificates of insurance may be needed to win contracts or gain site access. Requirements vary by state, so make sure you're in compliance with local laws and industry standards.
